Monday, discovered my pool turned green overnight. It's a lightish green color, with no apparent algae on the sides or steps, but when brushed dust is created. What I have done so far:
I have only basic walmart test kit, but the stats look fairly good and pool store confirmed this. I did panic and purchased silver algicide, per the pool stores suggestion, which I did apply with chlorine
Monday: added 35oz 67% triclor shock and turned pump on 24hrs. Also added remainder of 6% bleach (about 140oz)
Tue evening: added 182oz bleach and 8oz silver algicide. before bed added another 182oz bleach
Wed morning: added maybe 3oz silver algicide
So far color has not changed much and I have been brushing about 5 times a day. I backwashed my sand filter before the algicide and pressure has stayed at normal level. Before starting algicide and bleach ph was good around 7.6 i think. Now after testing in the morning looks higher around 8.0. Chlorine level is high, but walmart tester remember. Should i lower ph now, or wait until pool starts clearing up? reading could be off due to tester and much chemicals? What's my next move? I plan to continue adding chlorine... i understand that I cannot add too much?
Thanks for any help.
estimated stats before beginning above process:
TA: 100 to 120
NOTE: i'm not sure about my pump. in the past the pool will get hazy and not able to see from side to side under the water, but leslie's ultra bright clears it up overnight. The pressure does increase over about 2wks by 10psi and backwashing reduces the pressure to normal. seems after backwashing it will return some dirt into the pool from the returns, but stops after awhile. it's a rental so can't put too much effort into it.
