im using a 30gal res

i was wondering what air stone pump is good to use in a 30 gal res

A fish tank pump will be fine i use one in a 50 ltr tank but have used one in a much bigger tank.The all idea behind the pump is to keep the nutes on the move and airate the water with the nutes in.I have come across another great way of improving the yeild and root growth,have air rings in the bottom of the pots,then fill with soil and have the pump running 24/7.Its not a new idea i got into this years ago but since useing auto pots things cant get any better............................tyke

I like Active Aqua Round Stones. They come in 4" which is perfect for a 30gal. reservoir.
