If you've been following my story, you know we moved the pump and filter equipment. That equipment was down nearly 4 weeks while this went on. While all this was happening, I got my TF test kit and posted numbers that were decent. The CH was high, nearly 550. Some of you mentioned draining half the pool, which on researching I found out a way to do it - I was going to let the chemicals mostly leach out so I could dump in part of our yard where this had obviously been done before (we are on septic, this is city regs). When I researched that, it turns out that I had to fill out a variance for our water service (didn't know about this) which allows us to refill the pool once every 5 yrs and not get charged in their Tier 3 or higher rates. Because I just found out about this, I sent in the variance this week. Unfortunately, I'm not going to be able to do this for another 3 weeks or so.
I measured my numbers this morning, except CH.
FC 4.5 (I dumped in a bunch of chlorine yesterday - have yellow stuff on the walls (algae?))
CYA less than 20 (I could still see the dot and ran out of space in the tube)
Entering this information in the pool calculator, I see what I need to do - muriatic acid to bring down the Ph so the chlorine is stable etc. The TA needs to be increased from what I read and also need to raise the CYA, correct? What order do I do all this? Is there one item better to increase first and then measure again?
As usual, thanks for any help
