I think this may be your third post on this thread and all three have been negative, wrong, or both..Lots of us have identified the issue, the OP just doesn’t believe it. Yes, sterile tank, plus young tank, plus consistent fiddling and not letting a system properly mature.
Can’t force people to listen…
As has been said three times already, I have been listening, I have been taking advice. What’s the point of posting if I wasn’t planning on executing the troubleshooting that others suggest?
Please, if you would like to post in this thread, at least skim through the old posts and realize that I have done just about everything that has been suggested short of renting a par meter, and please, be kind!
