could someone tell me how to use the reverse flow option on a power head. i have a 402 aqua clear power head for a 30 gallon QT with a undergravel filter How long to use the reverse flow part is it used all the time or for a little bit just to get deitrus from out of the substrat. Any info on this would be a huge help. Thanks in advance for your care and help.
