try doing that with like 5 70 gal reses in one day. it seems like your just thinking of any way possible to hate on AN. i would rather use ph perfect any day than have to go through all that shit. also in aero if you cant change the water quick enough plants will die. tribal stop thinking about yourself only with a 30 gal res. what about people that have 10-20 lights? your not the only person in the worldWell, its not like Im pedaling a wheel that is generating the electricity to power some machine that filters my water. I turn the knob on my hose and when my tank is full the float falve shuts everything down. Then I come along at some point during the week and turn on my pump that shoots the water into my res, then I go vape some herbs and come back later and mix my nutes.
