Okay i have now decided im switching from the small 7.8L air pumps per bucket and cylinder air stones, with a higher grade pump and air diffuser rings. i might have at MOST 6 buckets. but really plan on having 4. so what gph would you guys think? also, can you adjust those air pumps? i would assume it would be better to get a stronger air pump and turn it down if i had to.
