Here are the most recent test results:
FC 2.5, CC 0, pH 7.7, TA 70, CH 400, CYA 40, temp 81
2 months ago, some of the numbers were:
TA 100, CH 360, CYA 60
Goals according to pool calculator:
FC 3-7, pH 7.5-7.8, TA 70-90, CH 250-350, CYA 30-50
Since taking over pool maintenance, all I have used were bleach and MA.
I've noticed that for the summer, I have to add much more MA. pH increases avg 0.1/day if not more.
TA was 120 at one point. The pool has a spa spill over. I've redirected returns not to point towards the surface of water anymore to decrease aeration. I've never had to add any baking soda.
Any red flags with these numbers, trend? I need some reassurance.
In my case, is it reasonable to get some trichlor since it'll take care of CYA, pH and FC? I saw some trichlor on clearance. It seems to be useful to have on hand for use during vacation as well.
