Hello, New to Forum.

OK, I'm a little slow with picking things up so please bare with me. Confused why my pH would be going up when I'm only adding bleach and no new water? Readings yesterday FC-8.0 CC-o pH-7.5 TA-160. I added 2 doses of bleach after dark last night wanting to up my chlorine since I didn't clean out pool yesterday due to running around town and always lots of stuff from tree in bottom. Now to this morning. it's overcast at the moment. FC-11.6 and pH8.0. Checked pH with my high pH kit and reads 7.9. Why would it go up? I keep my output jet aerating mostly also. Assuming I will need to breakout the muriatic acid which I was hoping to avoid? :O(

Here is your answer. Aerating the water increases pH.

LOL. Ok. well, guess I'll stop that then. LOL Duh.

There's a little more to it than that: aerating strips carbonate alkalinity, which in turn raises the pH. That's a GOOD thing, if your TA is too high.

For most threads, I think the idea of *KISS* is a good thing.

OK, My pump totally sucks. What is going to be my best reasonably choice for a replacement. It spits out a lot of what should be in the filter and several times a day have to back wash and thae the output jet off and clean cause so much big stuff comes back out and clogs it up.
