Setting up Undergravel filter with one or two powerheads?
Looking for some information on setting up Under gravel filter. My son and I are going from 10 gallon tank to 29 gallon. I have used the UGF with the air stones the last 2 years with the 10 gal tank and a whisper filter. I will be using a whisper 30 and the UGF in the new 29 gallon tank. I was wondering if I choose to put power heads this time do I have to use two, one for each side or can i use just one? As the water flow may be too much if two are used. I have looked for information and asked may clerks in pets stores and no one has a clear answer or idea. If someone could help?
