How much water circulation(gallons per hour) would I need in a 125 gallon tank.
Currently as far as powerheads go this is what I have:
3 maxi jet 1200--->each one is 295 gph
1 powerhead, cant think of the brand that is 270 gpg
1 more that is 170 gph
so adding this up I have 1325gph.
Is this too little or just right or what.
I also have 1 air pump, not too powerful with 2 clear plastic thin air hoses which make the water bubble a bit.???????
