Filter advice please?

[POS_miniracer]

I'm considering buying a wet/dry filter set up for my 90 gallon (340 liter) tank and I came across what seams like a good gently used one but it was being used on a 200 gallon tank and has a pump rated at 3100 liters (or just over 800 gallons) per hour.

Is there such a thing as turning the water over too many times in an hour? or too fast?

I'm assuming the larger the volume the stronger the current?

Is that going to be too much current? Do they even create current or "nozzle pressure" like a canister does on exit?

Thanks guys

I have never used those filters so not sure of them at all but yes you can have too much flow.

As above but you can reduce the turbulence by using spray bars with large holes in them to reduce the velocity on the outlets.

So far so good. Took me a couple tries to get the hang of siphoning through the overflow U tube but I got lucky with eyeballing all the adjustments and seem to have it just right the first time.

Surprisingly, not the jet stream of water on exit that I expected. But I like the idea of having a spray bar anyway so I might just make that this weekends project.

How's the wet/dry filter set in the 90 gallon coming along? Did you put in on an overflow box?

I did. It came complete with one. I ended up with a much lower flow pump though. It also has a Fluval 405 that's been on it since before the wet/dry.
