hey hound.I changed pumps and it's still not holding numbers, things are so out of wack. I took weenie pump out and changed it for a big one, put in the valve before the first water line in my res. set all of the nutrients in res and each module to 5.8 for ph and 300 ppm for babies and the next day my res was 700 and ph of 6.58 and each module was different from not only the res but every other module. I've searched all of the forums and you seem to be the only one having it work. Most others are converting to ebb&flo/Drip combo or putting inline pumps in their line somewhere to kick on periodically to recirculate. General Hydroponics should address this.

GH WATERFARM USERS: SIMPLE RECIRCULATING SYSTEM Ok so I was at my hydro store yesterday and the BRAIN pulls out this kit from GH that makes your w/f set recirculating!! Ordinarily this isn't very exciting news EXCEPT...... Get ready.......:jointsmile: It uses an air pump and drip ring set up to move the water through the system. You do NOT NEED A WATER PUMP! Let me repeat that part: YOU DO NOT NEED A WATER PUMP. IT RUNS OFF A BASIC AIR PUMP. Rating: 5
