Not sure what Im Going to do now maybe I'll leave it alone. If anything thinking of plumbing a tube to the outside to bring up PH in tank.
That's what I did Joe and it works great for me. You will need a 12" x 3/8" concrete drill bit and drill slow. I used power grab to seal around the 1/4" airline tubing, covered it on the outside with an angled elbow with a piece of window screen zip-tied on the end to keep bugs and spiders out of the line. The other end went into the air intake of the skimmer. My ph today was 8.3
