Hi everyone. I have a power head hooked up to my under gravel filtration in a 29 gallon tank. What is the best placement to direct the stream without creating a wind tunnel? I have 4 black phantom tetras and they seem to be having issues swimming. It is directed to the left along the back wall just being the filter leg. Is it possible to overpower a tank or fish?
