Was this the thread/posting? @Coltfire

ty@ ktreez420 , I looked in my post but couldn’t find it so started going through all the ones I had read ,I’ve now gone to sand, as the ph. went to high, so did a flush only to find the algae, had clogged the mat at bottom of pot, I could not believe the build up in the bottom of the pots, back to where it should be.
