My 125gal tank is 6 feet long and I feel it needs better water movement across the length of it.

Anyone who has similar ideas and solution?

tks

I'd use a wet/dry with about 500gph and a large canister, say Rena 4 or a, ehiem 2260 etc. That's about 1000gph.

Use some Lok Line to direct the flow in various ways, patterns etc.

You can also use the Hydro Korlina powerheads or run them on a timer/wave maker etc.
