I was up late last night in Eskobars thread. Reread and up to page 310. I believe I found the issue, and it’s two fold.
I charged the growpito too low at 5.0-5.2ph, and maintaining the res at 5.8.
I have a fellow over at AFN who runs this medium in autupots also…he swore by it and led my decision to go that direction. Between him and the growpito salesman I’m misinterpreting things…
Today I pull the 4gl containers, flush the growpito at 5.6, refill res at 5.6 and turn the res back on. Added a water pump… it’s a bit too large I believe and warmed the water/raised the value to.much.
I’ll get there… thanks for the input. Hope that was clear…
