Hey blades, I just set up a 4 bucket recirculating bubble bucket system, designed after budslingers setup. The air pump I bought is the eco air 4, which pumps out 9L/min. Is this enough?
What I used is a rena 400 air pump that said it can pump 160G Running at 2x4.35 psi and 2x52 gph. I can split in into 4 buckets. Plants look fine.
i looked it up and it is a 12 watt pump. you need about .5 watt per gallon so im pretty sure you are in the safe zone
basicly the same thing more watts means more power meaning more l/min. i think of these in watts because some pumps dont say how many l/min they have but all of them say how many watts they are.
