I was wondering about this.
I'm looking at a Tunze turbelle 6105 which is controllable between 3000 and 13000 litres/hour. My present powerheads are rated at up to 5500 litres/hour and make little impact on the flow in a 6x2x2 as far as clowns are concerned so I thought I'd try something bigger.

A few questions for anyone able to help..
1) Does anyone else use similar flows in such a sized tank?
2) If so, does anyone know if you can get a suitable grating for the front of that particular pump as it seems to be too open for use with inquisitive fish species
3) Lastly as a passing thought. Does anyone use a wavebox with clowns? I'm interested to know whether the effect is ( as I would expect) inappropriate.

Many thanks in anticipation

Do not know anything about them, but just did a search and found the below. To me, it seems a little over kill for a fresh water tank. And, really expensive.

Just read the reviews, they like em don't they?

I use those type of pumps on freshwater and marine aquariums, I find them nice for circulation. Because they do not have an direct flow, as traditional pumps or filter outlets would, it is possible to use one which would normally be overkill without much downside. If you want an example of how strong the direct flow is, a pair of my blue rams have made a home in front of a 900 lph one, so they will spend most of their time swimming as close as a few cm away from the front of it without any visible effort.

I haven't tried the Tunze ones, only the Hydor ones.
