Leonardo's Lagoon

Leonardo,
Amazingly beatugful your setup, very diferent and nice... I´m also running a reef that shold be considerate intermediate from what you have designed and a traditional reef... using small pounds of rock and sand just as decoration.

By using Vodca you probably reduce ORP... is there a good idea to use O3 to rebalance ORP ?

best regards

Leonardo,

Where are your Tunzes placed? Do you like the wavebox with the streams? Which settings do you have the streams on? Did I read that correct? You are gluing the maricultured pieces to the bottom? What kind of glue are you using?

Thanks,

Matt

Hello Matt,

The Tunzes are places right beneath the surface in the left back end of the tank. With the black background they are barely noticeable and easy to take out and clean.
I took the 6201 pump out of the wavebox and use it as a normal stream.
I have 3x 6101 and 1x 6201 connected to the Multicontroller, using interval 1 (2 pumps max./ 2 pumps min.) switching in 6 seconds. The pumps themselves are pulsing 30% - 100% in about 3 seconds. You can understand this creates a lot of flow in such a shallow tank with this volume.

The corals are glued to the bottom right now using superglue gel. I did this to prevent them from falling or sliding against each other due to the flow.
Next month, during the relocation of the tank, the corals will be glued to some rockwork.

Thanks Carlos!

the tank will be a bit more traditional next month, when I'm adding a bit of sand and rock ;)
I'm aware I reduce ORP a bit when using Vodka (although I'm skimming heavy) Because the tank is connected to the room where I sleep, I don't think it is safe to use ozone...
Besides that I like to keep things simple and fail-safe :)

Small Update...

Small Update...

Small update....: "Never use GFO in a carbon driven tank." Of course I've read it before, but I thought I could continue the use of a small amount of GFO in my tank.
That was a mistake! I'm dosing carbon for more then a month now, and my tank has reached very low levels. Replacing the small amount of GFO was a bit too much for my corals.
Several Acropora became very light in color, one of them RTN'd from the bottom up.

The soon I noticed this (next morning) I switched off the GFO reactor, cut back the MH, and started to feed heavy.
Luckily I didn't lost any corals, RTN has stopped. The light Acropora are already regaining zooxanthellae.
I continue to feed more then usual for the next few days and only light the tank with T5. After that I will gradually build up the duration of MH lighting.

So... Don't combine GFO and Carbon! ;)

And I thought my English was good :o Ow well, it is not my native language, so I have an excuse.

I ment "COMBINATE" of course, and not "combine." :)

your tank looks AMAZING !!!

So you are saying that if we dose carbon (Vodka) we shouldn't use GFO ? Because I change my GFO last week and it was due for a month ... I have some coral bleaching, the GFO could be the reason ?? After reading your post, I shut off the GFO reactor, we'll see if the regain some color (finger crossed) but why should we dose vodka and run GFO ?? Too low of nutrients ?

Thanks

Why do you think the reason is?? I've run Carbon/ GFO in combination before and don't see any issues there?? :confused:
 
Ed, Maybe you just have enough nutrients being produced. Have you tried not using either to see how fast they go up? Leonardo's system would be a relatively low nutrient system (my opinion) whether he dosed carbon or not, so to combine GFO is just taking too many nutrients out as he stated.
 
You can still run Carbon and GFO together but what he's referring to is not running GFO while dosing a carbon source such as vodka, sugar, etc.
 
Aaaah.... I understand.

Well, FWIW, there is a lot of zeoheads out there (me included) that do run GFO and Zeo together. However, we do take the GFO offline when the Po4 is nil and hook it back up when there is a slight increase :)
 
Glad to hear you caught this on time and that your damage was limited.

This seems to happen to a lot of tanks I know in the past year. Again all in the name of completely eliminating PO4 with GFO...

Leonardo, I dont doubt that you will reach your objective with this tank, I must ask though, does this accident make you reconsider the use of GFO altogether? Look at how quickly that went!?

It seems theres a fine line which you and other hobbyists are aware of while using GFO but are you not worried that this could happen again and perhaps do more damage?

Thanks! Coral bleaching can be caused by a lot of things, so it is hard to say that it was the GFO.
In my experience it is dangerous to make the tank too clean too fat when you already have very low nutrients due to carbon dosing and then add GFO to lower it even more.
But of course it depends on how much GFO you use, how much carbon you dose and of course what your bioload is. etc. etc. I

Green Thumb; I don't think I will use much GFO anymore now that I dose Carbon sources.
Maybe from time to time I will try very little amounts and see if I notice any improvement :)
 
Because my corals were so stressed my tank was only lit with T5 for the last three days. Today I started to slowly add some MH to the lighting schedule.

Besides the slightly darker colors of the SPS tissue due to the increase in zooxanthellae I noticed that many corals started to form new branches on the tips. (slightly larger corallites)

I just tested the Alkalinity three days ago, and it has dropped from KH 8 to KH 7.
I dose balling, so it has to be an increase in calcification.

I'm not sure what I'm going to to with this experience, maybe I will build in one or two days of only T5 (no MH) in my lighting schedule.

Anyone with similar experiences?

Thank you leonardo, I shut down my GFO, and my coloration is better, coincidence or actual source, I don't know... Hopefully, I won't need GFO anymore :P I'm running Nitrate between 0 and 2.5 and like i said my GFO was due for a month or 2 so is it possible that the "shock" or changing to much GFO at the same time could bleach my coral ? Also, I only observe this in monti and 1 acro. BirdNest and Pocci doesn't seems to be affected at all.

Thank you
 
Too many GFO too fast can shock corals... Keep an eye on your phosphate levels and if they rise, add some GFO. But do it slowly and small amount at a time. :)
