What Size Powerhead

[NathanPrince]

Hey guys, my main tank has been having green dust algae problems on one side of the tank and its getting annoying having a massive flow deadspot over that side. Also some of my plants on that side are getting 0 flow, I have lily pipes on my filter atm so could that also be a problem? I was looking at buying the original pipework with spraybar anyway. Its a Rio 125 with a TT EX1200 filter (how I got a deadspot I don't know!) so what sort of size should I look at getting? Scanned Ebay but only found 3000LPH+ and that seems a little excessive.

Also where would I place it, the opposite side as the filter flow or next to it to increase it that way?


Thanks

3000 LPH is gross overkill in my opinion. You just wanted to move some water in a small area so get one designed for maybe a 20 or 30 gallon tank, like an AC30, and mount it nearby. It should give you plenty of flow in a small area.

Yeah thought it was a bit high, want more flow on that side not a washing machine lol.

I shall have a flick through and see what else I can find, would a Hydor Nano work or is that too big too?

I have a koralia evo 2800 on a 350 litre tank and wouldn't want any more flow on that, would have thought one of the nano pumps would work well on a 125, what one you get would depend on the fish I expect, some fish can cope with more flow than others.

In this tank I have Bronze Corys, Bolivian Rams, White cloud Minnows and Otos. Think they can all cope with a bit of flow so I'll look into the Nano's I think.

Thanks for the help guys

I'd imagine something like http/www.aquacadabra.co.uk/PICO-Evo-Mag-1200-with-Magnet-Attachment-and-Free-Flo-deflector.html would work well in a 125l, depending on whether you were after a focused current or a hemisphere. I've heard this Hydor powerhead model is basically a rebadged Juwel internal filter pump inside a securing bracket.
