Hi all, first post here, been browsing the site since I bought a home with a pool 2 years ago.
I have always had a pool service come put chemicals in my pool, at $50 a month I thought it was reasonable, but after an algae bloom this past Easter Sunday, I am going to let them go as this was the second time in a year this happened. Each time it did, I tested the water (with HTH strips) and sure enough the free chlorine (FC) was zero.
So now on to my question.
As of right now my CYA level is 30-50 (strips, yes I know, im ordering the TFT-100)
With lots of sun on the pool, How much will my CYA reduce weekly?
Why do I care? Because I would like to use trichlor tablets and trichlor shock.
Why would I do such a terrible thing? Long story short, I can get it at a very discounted rate, much cheaper than liquid Cl bleach.
My pool gets a lot of sun, full sun from 7am to around 4pm, then half sun from 4-7ish (730ish is around sunset right now).
I would like to use the tablets for convenience and cost, but would the amount added considerably outweigh the amount lost to UV penetration?
TIA
FWIW pool service used liquid chlorine and copper algaecide.
