There is an article about David Saxby's reef tank where he talks about having an octopus when the tank was first setup in order to eat mantis shrimp that were hitchhikers.

I'm not sure if the octopus was able to get all of the mantis shrimp, but David did mention in the Practical Fishkeeping article that he is currently battling reef parasites of some sort.
 
I have heard good things about Cree LED lights from seemingly reliable sources. The positive reports (read as hype) of the earlier generation LED's were just as positive so I will reserve my personal opinion until I see them with my own eyes.

I don't like the look of the light that T5's emit and suspect that even these newer LEDs will have the same eerie, fake look, but like I said the sources of these positive reports are getting more reliable.
 
i used to have 20 of those red mangroves in the sump for my 40 gallon system...they were all over 2' tall as they where touching the underside of my stand from the base of it...they worked great for me...if you dont want those huge roots they develop just keep the water level consistent..i got them as pods (seeds) for a buck a piece from a local reefer who imported a butt load of pods...

your build looks awesome so far...would love to check it out when it is all done...
 
LED Lights welcome the future Now

LED Lights welcome the future Now

Sean, I am meeting with a Philips engineer to discuss the LED's. The commercial systems are capable of throwing 5000 lumens 500 ft. This is extraordinary light power. However it has not been designed for aquaria even though it is suitable for outside wet weather. The light we see in theaters is 12 to 16 lumens reflected off the screen. Also these lights are capable of throwing any colour through program management with the red green blue led's. I do not know yet whether any non visible light spectrum is produced like UV along the way.

Are there any definitive specifications for LED's that meet a baseline criteria for our hobby?

I have seen some very encouraging anecdotal references but nothing that would prompt anyone to spend thirty or forty thousand dollars on a lighting system with any degree of confidence that there was a beneficial comparison between traditional and LED lighting arrangements. If there were some science to support an available algorithm I would think that based on the limited experience I have had with the capabilities of the Philips commercial system that the programming flexibility to choose any colour light, any frequency and any degree of saturation would be game changing for this hobby. But everything I read is far from definitive. Part of the justification is that the current generation of LED's which have only now been practical are still too new to deliver any confidence to the end user.

Thoughts??

Peter

Peter I really congratulate your efforts.
Sometimes in the lonely place reserved for professional aquarist I wonder why takes so long to produce change.

Perhaps because most of the people in the trade is made on trial and error and the profession as is doesn't exist.

Anyhow my point is LED should be the way to go but the change is taking so long because is affecting the whole illumination industry and our part there is tiny microscopic.

I personally been working with LED and I can reassure you that I have never experience before the polyp extension in sps coral like this.

The fact is that combination of LED lights can stimulate the corals to a degree never met by any other type of lighting. Plus the different dimming combination I think soon the whole industry will open.

I look at MH lighting like the gas guzzlers of the aquarium hobby.

I hope you and those Philips techs can come with a solution for your tank.

Sincere regards

Yes he was but the most significant thing to me was the understanding that he expected to do battle as part of the ongoing management of the ecosystem........a very mature philosophy I think and I applaud him for it.

Update......

Update......

I just checked my live rock and apart from the gooey, smelly, ickky stuff in the two skimmer cups, the water is clear, still no bad smell, colours are still strong and sponges of various types are still healthy. Temp has fluctuated between 72f to 79 F. I keep moving the heaters around. I have added RO water to the two tanks as the evaporation moved the salinity to 1.027. Air bubbles are strong and there is relatively good water movement. It's not Niagara falls but I think there is enough motion to keep everything good. I am making more fresh salt water so that I can do a substantial (450 gal) water change next week.

The final details on the HVAC system have been settled and work begins tomorrow. It involves a number of systems to cope with the seasonal extremes and also not interfere with the overall air and humidity balance in the house. I will be taking pictures!!!!

The sled of equipment is scheduled to go into the fish room three weeks from now. It has been reconfigured to accommodate the doubling up of the CL system. And we will be using additional live rock filtering over the original plan....I will be taking pics :thumbsup:

I have decided to try and arrange to do the majority of rock sculpting in the 500 gal large temp tank and then move the results into the display tank rather than do the finicky stuff in the display tank. There will still be some assembly required in the main tank but all the moving around will be easier to do in the temp tank. One question I have is that I expect that the live rock will continue to be submerged as it has been since it's arrival, however I will be moving it through the house when the time comes which would have it exposed to the air for about three or four minutes. I am assuming that this is ok???? Technically I could keep it submerged for transport but it would add a significant amount of work to the process.

I am probably going to reach out to MR. Wilson (don't tell him) to assist in determining the best technology to monitor and manage this stuff. That part of this build I am sure will be full of healthy dialog. I am still struggling with the lighting configuration but I can say that I am actively pursuing the LED technology as it does show some significant promise. I suspect I will be breaking some new ground here based on the limited research I have been doing so far.

More on this later............ I have to say I am very thankful for the community staying so loyal to this thread. It is one of the primary reasons I am as committed to this build as I am. You folks are the core of my courage and I appreciate your support.

Peter. Exposing the rock to the air for three or four minutes is no problem at all.
BTW, what brand of salt are you using? Just curious.
 
You will be fine having the rock exposed to air for 3 to 4 minutes. This stuff is way more resilient than I think most of us give it credit for. My liverock has been submerged for 8+ years and has lots of life/sponges on it. I have re-aquascaped multiple times with the rock exposed for up to 30 minutes (making sure to keep it damp) and haven't noticed any die-off. Many people say that there are a few types of sponges that die instantaneously if exposed to air, but I've never witnessed this.

I'm assuming that you will be affixing pieces of rock together to form larger structures. What product do you plan on using that will allow you to do this underwater (ie. will cure while submerged)?

Deep Ocean sea salts......It has been suggested that its ok for the live rock but another brand should be used for the main display tank. I will be looking for suggestions.

Thanks BennyFrank, your question is timely I will be using the same compound that Chingchai used for his build and I will ask him here if he wouldn't mind sharing the info with us. Its an underwater compound that doesnt seem to leech anything back into the tank and as you can see his reef still stands today!!!!!

Well. I can suggest only two brand that I use
- Reef Crystal (made in france)
- Tropic Marin Pro
TMP is more expensive but I don't find any difference.

This is the one I use:
A+B Epo putty 100g
http://www.alteco.com.sg/products_epoxy_a&b_epo_putty.shtml#
It costs US$3 per pack.
If you can't find it there, I am happy to arrange shipment for you.

If you time things right you can use the old water from the rock vats to jump-start your fish room tanks. If the old water is rich in ammonia or other forms of nitrogen (nitrite & nitrate), even better as it will feed the nitrifying & denitrifying bacteria you are trying to establish. Cycling a reef tank full of rock is relatively easy, as the rock is acting as your biological filter. Your system tanks sound like they will be devoid of rock at least initially, thus calling for a more stringent cycling protocol.

When I started in the marine hobby in 1979, the accepted method of cycling a tank was with black mollies or dead fish. Later we got more scientific and dosed ammonium chloride daily while cycling a tank to feed the beneficial bacteria. As reefkeeping continued along its slow path of evolution, the cycling chemical of choice was sodium nitrite or potassium nitrite, as the bacteria that converts ammonia to nitrite is quick to establish but the accumulation of nitrite takes a few weeks before it reaches a critical mass where the beneficial bacteria that consumes it can start doing its job. In the waiting process, nitrite spikes and causes fish and or invert mortality. In other (hopefully simpler words) adding nitrite speeds up the process and make minimizes toxic nitrite spikes.

The sled of equipment is scheduled to go into the fish room three weeks from now. It has been reconfigured to accommodate the doubling up of the CL system. And we will be using additional live rock filtering over the original plan....I will be taking pics :thumbsup:

If you are using live rock in the wet/dry filter you will improve the efficiency of nitrification, but in the process increase the build-up of residual nitrate. Rock is much more efficient than plastic media so your wet/dry filter will be doing exactly what some of the others have warned you about (creating a nitrate factory). One benefit of live rock is it potentially offers localized denitrification through anaerobic denitrifying bacteria within the rock. This means that the ammonia, nitrite and nitrate may all be assimilated with one stop shopping on the same rock site. As neat and tidy as this may sound, biological filtration is redundant as you have more than enough surface area for beneficial nitrifying & denitrifying bacteria on the rock and sand in the display tank. Any more rock in the system is therefore just expensive filler.

I would investigate more fruitful ways of using the resources you are using with the wet/dry filter box. If you have the water flow through a drip tray and just rain in the box, it will help with gas exchange thus stripping Co2, and nitrogen gas while adding oxygen. It will also cause evaporative cooling which will take some pressure off of your chillers.

You haven't disclosed your full filtration plan yet, but perhaps there are other technologies like refugia that would work in the wet/dry space. I can't knock ATM for including a wet/dry filter in their design as they traditionally set-up tanks with artificial fiberglass & latex rock structures that offer virtually no viable sites for beneficial nitrifying bacteria. In these cases, the wet/dry filter is essential, but in your case it is redundant (some would say detrimental).

The principals are very simple here. You just need to stand back and decide what you are trying to accomplish then decide how to get there efficiently. Reverse engineering devices without looking at how they all fit together will only cause you more sleepless nights :)

I am assuming that this is ok???? Technically I could keep it submerged for transport but it would add a significant amount of work to the process.

Just remember how heavy the rock is and how hard it is to replicate what you have created even carrying it a few feet. Do a test before you invest too much time in the process.

Sponges shouldn't come out of water, but personally I wouldn't go through the extra steps of moving them in water as they will inevitably be in the air at some point in the process. Brief exposure to air is not a problem for bacteria and algae.

I may be out of reach on that one. While I've used a number of controllers over the years, I'm not a programming genius like a lot of these IT guys who are on RC all day while they are at work :) The Profilux controller is very popular and simple enough to use, but the box looks like tv converter from the 80's and is hard to mount. The connectivity is a little outdated as well. It's a German product with some info lost in translation. Someone on another forum wiped out his tank by misunderstanding the pump shut-off sequence.

The Aqua Digital Reefkeeper V2 is more compact, easier to program and has more modern connectivity. Elite http://www.digitalaquatics.com/ I like that it has a user friendly, intuitive iphone interface. I assume it has a blackberry application as well. Do some research and figure out what you what to control and where your fail-safes and redundancies will be.

In addition to the main controller interface there are modules that control specific parameters like redox potential (ORP) and PH etc. Aqua Digital offers PH, salinity and temperature all in one module which cuts down on clutter. You should have one PH module for controlling a calcium reactor if you are planning to have one, and a second PH module to monitor the system water. This is a good way of checking night Ph drops due to coral photosynthetic respiration at night as well as elevated Co2 levels during parties. The PH can also climb if you are dosing too much kalkwasser (calcium hydroxide) or other KH or calcium buffers. You can employ the controller to make necessary adjustments (raise PH with kalkwasser or sodium carbonate, or lower PH with Co2 or sodium bicarbonate) to rectify PH shifts.

Top-off for evaporation is a science in itself. Use as many fail-safes as possible. I use an electronic float switch (mercury/reed switch) and solenoid to govern a peristaltic metering pump to add an appropriate amount of water as it evaporates from the lowest (end) point in your sump. The metering pump assures that even if the system goes haywire, the pump can only deliver a finite amount of water (usually 8GPD depending on the pump model). Drawing top-off water from a 50 gallon drum that is filled, then allowed to slowly get used up over a few weeks is another way of assuring that your top-up freshwater is a finite quantity that would not adversely affect salinity or temperature even in the event of failure. It's also a good idea to use a secondary mechanical float valve (not switch) as an absolute safety. This can be positioned above the operating water level in the sump where the top-off water enters the system. If the water level in the sump is too high, then the mechanical float valve stops the dosing pump from sending more water. This safety feature comes in handy if and when the electronic float switch jams in the on position. You should also include a second electronic float switch that is set for a high level in the sump so it can shut off the dosing pump and send a warning email or text. Hopefully you already have an emergency overflow drain line in your sump that goes to a floor drain.

Of course the controller logs and graphs all the collected info so you can keep track of it on your computer. This is where you really need an IT guy :)
 
I would really inspect every single rock real good for any Manjo or Aptashia. If I found any rocks with them than i would just cook the infected rocks and add them later.
