700 gallon tank, or how i spent my daughters inheritance

[StripestheEel]

here is some odd behavioir from the Pink Tail Trigger. why?

The only time I have witnessed that with Triggers is under severe stress.

Eg; just purchasing the fish and acclimatising in buckets etc.

One thing I did notice was that the tank did not have much surface agitation and some scum build up on the surface.

Were you running pumps when you took the vid? Maybe it is a lack of oxygenation???

Something to think about perhaps.

Do you use carbon? If VOCs and other organic toxins are a concern, carbon might be a big help.

the surface stuff was just after stirring up the tank while sucking up debris during a water change. i have seen the same behavior another time recently on another day without the tank work. the overflow from the DT tank adds a lot of air. there is a lot of water motion in the tank as well. i don't think it is the oxygen levels.

he is still acting normally this morning. no change in appetite or other behavior. all other fish acting normally.

i always run carbon and have just recently gone from one to two large fluidized beds.

now that the weather is warming up i can open the garage more and get more fresh air flowing around the system.

i love the two urchins but they are ruining the tank with their bite marks. i think when i rebuild the tank i will relocate them to one of the glass tanks. they graze a swatch of LR leaving nothing behind.

the bite marks. i don't remember which one did this. i think it was the Diadema but i am not sure.

i got the new PAR meter. i haven't set it up with the computer yet to do the tracking over time. these reading were taken about 9:30am yesterday. sunny day outside. i don't think light is the problem, unless it is too much for new corals coming into the system. of course these levels fluctuate throughout the day as the sun moves across the sky. it can go up and down as the light reflects off the shaft at different angles.

you can see these readings are at the surface. i will attach the probe to the pvc piping like the previous meter so i can hold it underwater in a good position.

the light fluctuates even over a couple of minutes.

 

[porthios]

just had to make all our par meters look bad, didn't ya?

can't wait to see the data after you've had a chance to log a bit..

I was amazed at the coraline growth after my tuxedo urchin was out of my tank.

 

[Reefski's]

so what do you do with two urchins that are too big for a 700 gallon system? i can't turn them loose! they both love the coraline and the algae!

I agree with the stress answer. The only time I ever saw a trigger exhibiting that kind of behavior was during a fresh water dip.

 

[Reefski's]

very weird, and he is still acting normally. haven't seen that behavior since the photos. he has gotten less shy since i rearranged the tank and took out the turf scrubber.

he used to hide every time i walked in the room. now he is out looking for food.

Pam would like to go bare bottom for the ease of cleaning the tank without worrying so much about scratching the tank. I don't think so. She says we have enough sand and filtration in the other parts of the system. Thoughts? I just don't think it looks right and then there is the ecology thing too!

That's all for now.

I went Bare bottom and I love it. At first it looked kind of weird cause of the mirror reflection. The coraline algea covered all the exposed bottom in no time. I would specially go BB if your going to keep the CL, no sand getting into your OM. Only creatures that didn't like the BB at first were the hermits. They had nothing to hold on to and would get pushed around with the flow.

i saw a wonderful stony coral tank last weekend at Vivid Aquatics here in the LA area. 800 gallon display, 6000 watts of Halides.

What were the dimensions of the tank? Were they 400 or 1000 or a mix both, any idea if the were 20k or 14k?

vivid has combination of 1000 and 400 i thick its ushio 14 k

 

[Reefski's]

the tank is 12x8x3

4 1000 watt and 5 400 watt

i just was reading about a blue shade cloth i will investigate a bit more to shade the sun a bit and give a bluer look.

the ChromatiNet Blue http://www.signaturesupplyonline.com/

we painted the inside of the garage yesterday with a zero VOC acrylic latex paint. mythicpaint.com

 

[Reefski's]

oops, tank is 12x3x3!

 

[erics3000]

got you the 12 x8 had me drooling but new that wasn't 800. hahhahah

Great link. You are really making it hard on me trying to hold up on cutting a hole in my roof.

Eric

as they say "just do it"

you won't be sorry.

i wonder how much it cost for electricity and bulb replacement and equipment costs for even a year compared to cutting that hole in your roof. i bet the payback time is not very long.

i bought the blue shade cloth. about $50 for 30%, 50%, and 70%
