i'm using hydroton. spent days cleaning it. i'm using tap water its around 54ppm and 7.0 for ph. i let it sit in a 55gal rez with air and a pump to circulate before i use it on any plants. maybe it is the hydroton raising the ph??? i dont know, maybe its the plants??? i just imagined that once you balance the ph it would stay close to that level, unless you add something with a different ph
oh and its a new rez with fresh water. i dont think i have any bacteria yet.
anyone try advanced nutrients "PH perfect" yet?
take the airstone out the res and see what happens i know i know you will see people tell different but I bet you your ph will stay stable when you take out the air stone... leave the circulating pump in there but remove the air stone keep me posted
