Powerheads

[hensonc4098]

Hi guys

I'm having a bit of a BBA problem in the 180l which I think could be due to a lack of flow in the tank. I am not dosing any CO2, so this probably isn't helping, but I've noticed watching the tank that there are quite a lot of areas where there is little to no plant movement. The tank is a bow front corner, so not easy just to reposition the filter outlet, so was looking at getting a powerhead to increase the flow a bit.

Question is, what size to get? I've seen 3000lph (alleged) and 6000lph (also alleged) but not sure whether these will be sufficient or overkill, since never used them before. Either that or would it be better to get a couple of smaller ones and place them facing different ways? I have one spare plug in the aquarium unit, and another spare one in the wall outside the aquarium which I could use if necessary, so enough power sources for 2 if needed.

I can add a picture showing the tank and positioning of the filter just now if it would be helpful to work out the best place to add powerhead(s)?

Cheers.

I recently tried a 3000lph on my 300L - it turned it into a whirpool. Angels do no appreciate that sort of flow.

I can't recommend an alternative, but stay well away from the 3000lph+ ones!

I have a 3000lph one on a 266 litre tank, and it moves the plants quite well. i would not get a 5000 lph as your fish i think would not like it. Mine cost me £11 delivered within 48 hours. you can also get hydor 1600lph for around the £30 mark.

take into consideration your substrate if you have sand the 3000 lph if aimed down wards could cause the sand to move quite a bit. My substrate is Molar clay so its been fine.

In that case I might try something in the range of 1500lph to see how it goes. Didn't know what sort of flow they produced - glad I didn't get a 6000lph! Poor angels wouldn't know what had hit them
