First Post - thanks for all the outstanding info.
New pool owner as of last July, was paying someone way too much to do a terrible job and after learning a LOT on this and other sites decided to take it on myself. I've had a hot tub for 10+ years so I'm familiar with balancing water.
Long story short - my pool had/has several issues -
first mustard algae. Growing so much on the steps it was like velvet, could only scrape off with your fingernails. coating the entire vinyl liner.
second - staining - I have a TON of leaves. It's a struggle just to keep up when they are really coming down which seems to be almost always
My water is mostly balanced:
PH - 7.6
TA - 70
CH - 60
CYA - 48
Salt - 3100
Problem is when I run the DPD test it never turns clear/not pink. Being my first time running that test (Taylor Kit), I thought I must have just over shocked, but I've tried 4 times and have completely used up the reagent. I tried adding extra powder too, no difference.
I've turned of the SWG but I'm worried about my liner. I'd assume given the amount of algae there may be very high CC, would that throw off the test that much?
Needless to say I need more reagent but I thought I'd ask here in case there is something else I'm missing.
For the leaves, is there anything special I need to check or do given a very high volume of leaves?
Thanks in advance for all the help -
