First of all, MAJOR THANK YOUs to the Admins and contributors of this site. I've owned a pool for about 7 years now, and I'm finally making a dedication to learning the chemistry. This site has great down to earth articles that are easy to understand.
55,000 gallon pool turned green on me.
While I waited for my TF-100 kit to arrive (bought through TFP), I tested with test strips and noticed my CYA was through the roof. Probably because my dumb***** kept adding tabs to the pool (inadvertently adding stablizer with every dose and sending my CYA through the roof)
After my TF100 kit came in, I confirmed the test strips were pretty accurate:
My numbers are as follows:
Because I couldn't lower the CYA any other way, I went ahead and drained about 80% of the pool. Totally random, we got about 9.5 inches of rain the day I began draining the pool.
So the pool is only 20% full at the moment, and water is green as a slime monster. I haven't tested the water since the drain. I will be moving to the BBB method as I start to refill the pool.
My question is... should I try to kill the algae while the pool is only 20% full, or should I go ahead and start the refill and then move to kill the algae?
