Dimmer Switch And Powerheads

[jeffopentax]

I've got a 425gph powerhead in my daughter's 30g tank, but it's not quite enough. I was thinking i could use one of the larger ones i have laying around and dial it back with a dimmer switch. Any problem with doing that?

Only if the pump has the ability to be, but if that was the case, it would have its own controller.

I have hydor and fluval, which both claim to be compatible with wave makers, but i guess that 's not quite the same. Dang it!

What model of pumps? I am pretty sure compatible in this case is referring to simple rapid on/off states though

Yeah that's what I meant by not quite the same. Fluval cp4 and koralia 1400. Will have sicce voyager 3 next weekend.

I'd think 425 gph in a 30 is lots!

It's not bad, but very narrow. Can't get flow throughout tank. Could add another, but not much room in a 30g cube for hardware.

what if you put 1 power head in the opposite corner to the return...would that not keep the momentum to keep the flow going..

technically swapping impeller magnet for a weaker one would be most effective unless it uses a controller its probably just on/off and thats it if you dial down the power supply with a dimmer it might slow it but most likely it will just stop once you drop below the voltage threshold

Teach your daughter about hard work and have her just keep stirring the tank with a spoon.

OMG, don't tell her that, she is just a little girl and will get in there with a spoon, but, it is funny..
