Hi Karen - We met at the BRS meeting at Pet Club -
I remember that we talkad about wanting to set up 15 gallon tanks at work. I DID do mine a few months ago - at work. This is my set up -
15 gallon tank
3 Inch southdown Sandbed
15 lbs of rock out of my 72 gal tank
remora skimmer - I'll explain why . . .
aqua clear filter / micro chiller on a temp controller
JBJ lights - 1 55W PC, 1 55W actinic (with fan)
50 watt titanium heater
numerous polyps, shrooms, sponge, trumpet, purple plume gorg.
1 diadema pseudochromis. and 1 pistol shrimp/shrimp gobie pair.
I schlepp RO/DI in from home - for evap and 20% water changes every 3 weeks.
SO, to answer your question - I put the remora on the 15 gallon - I know it is overkill - but this tank is in a very high profile place. These people know nothing about sw tanks - just that they are pretty. I wanted to make sure that it WAS always pretty. Even with the small bioload I have, I feed heavily for the office to watch. Everyone loves to watch the goby/shrimp pair and the goby brings food to the shrimp . . . very cool.
Now, I have no control over the heat/cool during the weekends - and the DO turn it off. hence the chiller. It has saved my tank - 15 gallons responds very quickly to external temp changes. I have a thermometer that holds the high and low of the air and water temps. The air has reached 92 degrees in here, but with the chiller, the water has maintained the 82.4 degrees I have set. The low has been 67 degrees, and the heater has maintained the 82.4 degrees. All in all, the tank works and with minimal worry. Schlepping the water is a pain - I do the heavy work on the weekends so nobody will see the work. I have already sunk about 800 dollars into this tank, but I really love having it at work.
Let me know if I can help with any other questions.
