I have inground pool with hayward cartrige super star clear filter system.
I have been using BBB method since last year mainly using bleach.
In winter its was blue and clear now in summer no matter how much bleach i put it is still light green.
First want to clean the cartridge filter system (hopefully i can take lids off)
I have walmart brand hth test strip. I know eventually buy the the expensive testing kit mention in the forum.
My current stats are using hth test strip is
I put lot of bleach but it never turn blue almost 2 (10%) + 1 (6%) last week one gal bucket.
I guess i need to bump up my CYA level. Whats the best CYA brand leslie has it for 7.99.
Should i put cya and than dump more Chlorine? or vice versa anything else looks low than let me know.
