Cold Water Reef Plan

[Quagmire]

Those tanks of his are fantastic.I think if I was closer to the coast I would give a cold water tank a try myself.As it is living in Calgary finding livestock would be very hit and miss.As far as cost,it seems you must spend $$ on a chiller,but the cost is offset by not having to spend alot on lights.Other than that,is it just the insulated tank that is needed? and the rest of the equip pretty much the same as tropical tanks?
