We finished our pool late last year and have been using Pool Math to keep it balanced. But something got away from us recently and we could use some advice I think. The thing I first noticed were bugs swimming in our water last night! Ewe! My research indicates that these are probably water boats and backswimmers which may indicate an algae problem? I haven't seen any sign of algae but last week we had a terrible rain and the pool was very murky in the morning. We tested the water and there was 0 FC. So we added bleach and got it back up very quickly. But a week later I notice these bugs. Here are our test results as of this morning:
FC - 11
CC - 0.5
PH - 7.4
TA - 70
CH - 200
CYA - 50
Temp - 81
Pool Math says to add 13oz (vol) Borax and 56oz (vol) Baking Soda which we added today. Tomorrow we'll add the recommended 71 oz Calcium Chloride.
OK, so far?
My question is, Should we have slammed the pool since the FC went to 0? We've never had any CC showing at all until this week, so something has definitely changed.
Can we have your advice please?
