Default Circulation pumps for a 15 gallon.

Been looking at some pumps to help with some algae issues in my 15 gallon.I narrowed the list down to two the Hydor Koralia nano 240 or the Hydor pico evo.
Im just worried about buying a pump thats to strong most of the information I came across use the 240 in 20 gallon tanks.

I have a 240 and I think you'd be okay to use it. What sort of algae issues are you having?

Is it a new setup? The brown algae tends to appear in newer setups and eventually goes away once the tank is cycled. It can also occur in a tank that has had the bacteria balance upset recently for one reason or another.

BGA is usually an imbalance in N to P ratios. Try dosing a little more nitrogen and see if that helps. Erythromycin will eliminate it for good.

The tank is about two months old. Also checked my nitrates level and it was 0 could that be a problem?

Low Nitrates can be a cause of BGA, how old is your test kit? are you adding fertilizers to the tank? if so what & how much?
I agree with Aaron, the 240 would be fine.

If phosphate levels are not also zero then it becomes a problem. Try dosing some N.

I might have a bacteria imbalance I think, I used a piece of shrimp to cycle the tank won't do that again.
I looked at my test kit its a API master kit the expiration date is 2018 and I add Aqueon Co2 Booster everyday,plus Aqueon plant food weekly.Also I did add Flourish Root Tabs about two months ago.
Im going to order the 240 pump from Amazon tonight the erythromycin will be my last resort.
