I just got a Aquaclear 30 Powerhead for my 10g tank to help create better water circulation for my BGA prevention/removal plan and would love some advice for proper placement and water circulation.

I already have a powerhead, that I've owned for over a year, but it was just too powerful for my small 10 gallon tank, even this aquaclear 30 is on the lowest setting, and pushed a lot of stuff around when I first turned it on but not as bad.

Right now I have the powerhead placed on the opposite side of my HOB filter, angled down towards the center of the tank. I've also connected my DIY C02 to the powerhead. I'm afraid that it might be making my cardinal tetras unhappy, because of the current being too strong for them to want to be in the center of the tank, they seem to stay underneath it most of the day :icon_frow

What would you guys recommend for the best gains from my powerhead? Do you turn yours off at night? How do some of you position your powerheads?

I'll try and get a pic up here after work, Its not knocking stuff around anymore with the angle I've got it set at. I do know my BGA has other causes, I've started dosing nitrates to my tank since blue green algae is also caused from nitrate deficiency, but I was also told that low water circulation can be an added cause as well. I also wanted the powerhead to increase surface agitation to help with my DIY C02.

Decrease, not increase, with the HOB you should have enough surface agitation for both of us. :D

guess I've been getting mixed feedback then... I have had issues in the past that led me to believe it was necessary, specifically to help with my c02 issues. Anyways here are some pictures...


Could use some feedback on the condition of my BGA and this one plants I have, I cant recall what type of plant it is, but it doesn't seem to be doing very well, I'm hoping my new KN03 dosing will help it:

I dont know much about the algae, but I have my powerhead on with my lights and co2. The powerhead is just for hitting the co2 bubbles coming out of the diffuser and for low level water movement when the lights are on. My tetras dont seem to mind it but they have alot more room to swim in than a 10g. Using like a marineland 200(maybe a 100 I cant remember. Filter size A) is all I use on my 10g and it moves enough water I dont use a powerhead at all.
