For a 75 gal. 4ftx1.5ftx2ft FOWLR,which one would you suggest.I'm not sure of the ratings because i got them used sometime back,thats why i posted a pic.Fish in tank are 2 clowns and 2 damsels.Thank you in advance.
the more flow the better just like the real sea. I have moded MJ1200 and koriala 3 together is 2450GPH and i still think is not enough flow fo my tank.
i know they are not the prettiest things around,but i got them for like 15 bucks a few years ago.I still can't see having them all in there.That first one alone makes waves all along the whole tank,and makes my subsrate mound up so much my one side of the tank is bare bottom.Is there some way to avoid that,or just let it be.Thanks again.
The only thing I would worry about is how hard the flow is on that large one. While I agee flow is key and using all 3 would be ideal you dont want a hurricane in your tank. I have 3 PH in my nano along with the return pump on a loc line splitter. But the flow rates are turned down so it simulates a nice easy current.
