For the last 2 years every summer during this time and for the next three months I become an active reader of this site. I am eternally grateful for all the advice and clearing up water chemistry fundamentals. This year I am strictly doing the BBB method as I wanted to exhaust my BUCKETS of chlorine tablets/granules I bought being new to pool ownership.
Opened the pool last week as water was mostly clear though I did see some dark spots on the pool wall in 2 places (not much). SLAMed it everything seems ok with spots disappearing. My question is regarding the white stuff floating in the pool (picture attached). This thin stuff dissolves when the water is touched/agitated so I don't see it when the pump is running. Otherwise the pool is clear and my numbers are for the most part ok. It sticks or surrounds around any debris if that's relevant. I have searched this site and read some posts pointing to algae but I am just not sure if I have the same problem.
FC = 8.5
CC = 0
PH = 7.8
CH = 220
ALK = 80 (side question- how do I raise it safely to 110 without impacting ph or should I just leave it as is?).
Ancillary info: in NJ , lots of pollen and the cartridge filter keeps getting up 10psi every 2/3 days of the pump running 9 hrs/day since I opened a 8 days ago. I drained the pool 1/3 and filled it with city water when I opened to get the cya down from 100 last year due to use of chlorine tablets.
Good day to you all!
