Hey Shaggy,
do you keep the system recirculating all the time or does the pump run in intervals like ebb n flow, if so what feeding time schedule are you running I see your using latewoods 123... I'm using the house and garden line for hydro...another question I have is how high is the raised floor the tubs sit on...So these are basically a recirculating dwc containerized ebb n flow hybrid system so to speak...
