Druu;2335732; said:Go with the 75s. Unless you're going to need 125g tanks for larger fish, 6 75s beats the pair of 125s. (Assuming no additional filtration cost since you have the AC 110s on hand.)
Well I have 3 AC110s left. I pretty much like everything about the 75s, but its amazing how much difference that 1' makes on the 100 gallon. The 125s are even nicer, but they may be a bit much for me atm. I have a 180 that I don't like at all. 180 is just too big IMO to have in your house. Mine is in the garage atm, but I'm probably going to sell it.
