enough light for SPS?

That explains why you don't loose next to any water. The chiller is keeping your water stable thus not needing the fans. I might end up looking for a used chiller for my pod. What model do you use?

OH yeah, I just replied to your thread. That is a sweet coral you scored...
Nice

I use the JBJ nano arctica chiller. It was around 250. But I dont have any issues with temp/evap. I am very happy. It is very quiet and small too.

spankey,
your evaporation is due to the fans. water is cooled by evaporation. so to keep your water at 77* you have to lose water so your top off is more. i have a 60g with a chiller. my evaporation was very little as well. i added a couple of fans intentionally to evaporate more water so i could introduce more kalk via my top off water.

lbaskball45,
i personally do not think you should close off your tank from oxygen exchange on the top. could have some consequences that aren't good the more coral you add. just MPO. it's your tank do with it what you like. but the cap will quickly out grow a small tank! again, MPO.

i have a 26 g with a 150W 10K MH and I run two T5 actinics. The acros I had did fine till some disease wipped most of them out. I keep it open so it doesn't over heat, I can't really afford a chiller. But I keep bottles of refigerated water and add one or two a day, everything does fine with it.
