Yea, that's what I was gonig to say. AC 110's push a lot of water with more of a forceful flow than an FX5.Bderick67;3207163; said:I would think two AC110s would create more current then a single FX5.
Deepsouth;3207059; said:Have any of you put an FX5 on a 75 gallon? I have had one for quite a while and it filtered a 125 gallon tank just fine. I'm a bit worried though about putting it on a 75 gallon tank. I'm thinking that the current could be an issue. I have 2 AC110s that I could put on the tank instead, but I'm a huge fan of the FX5s.
