Here are my tank specs:
50 gallon acrylic tank with MH canopy
20G long AGA tank converted to a sump with a refugium ( inside purpose built tank stand)
Tunze 9010 skimmer ( in sump)
Eheim 1260 (634 gph) return pump
2 Koralia circulation pumps ( these are Koralia 1's)
JBJ 1/15 chiller
Eheim 1250 ( for chiller )
2 39watt highoutput t5's with geismann 6500k and blue+ bulb
2 250 MH to come when funds allow
I was originally going to get a 34 gallon cadlights tank so bought the chiller and koralia's with that tank in mind. I then decided to get a larger tank.
The chiller is probably a little undersized for the tank, but it seems to be keeping the tank at a nice constant 78 degrees, even when the ambient room temp is in the high 80's, so I'll have to see how it works when I get my MH's.
The Koralia's are also on the small side for my tank so I'll probably upgrade to Koralia 2's or 3's, just not sure which yet. They're very quiet and I like the sleek look to them, so I'll definately stick with Koralia's.
In a couple of weeks when I get my MH's I'll start slowly adding more livestock.
