First day reading the forum... first post after a few hours of reading...
So we bought the house recently and just continued service with the existing pool company. After about 9 months of pool plaster beginning to flake (looks like the surface of the moon now), pool plaster turning yellowy brown (metal staining) - they pulled the metal stains out with some chemicals later or so they say, then it cleared up for a couole months this spring... now i'm seeing black algae spots that have spread across the bottom.
In my opinion, my pool service company is just terrible and is doing a horrible job, but to confirm this, I've decided to inform and educate myself. I don't want to be THAT guy that makes complaints with not basis or understanding of whats going on. So here goes nothing:
I've been doing some research and I think I did my homework on the TFP beginners guide, reading through it, purchasing the recommeded test kit, I'm still in need of gathering exact pool equipment info but it's dark outside and I managed to remember basic details, and now here are the test results -
FC - 0 to .5
TC - 0 to .5
pH - 7.6
TA - 70
CYA - 75
CH - 650(ish - it said to do it drop by drop but after 60 drops i was doing them several at a time... it turned purple around 60 drops and blue between 65-70)
My confusion is why I have no chlorine in my water when I know there's a bucket of tabs by the pool, 3 dispeners floating (not sure if anything in them), and black algae growing on the bottom, oh and some green/yellow on the walls today.
Do i just need to add a bunch of chlorine or is something (ie my pool guy's lazy/not doing his job) or is there something causing the water to not "hold" chlorine?
I noticed the CH value is higher than the recommended 150-400 listed in the test manual.
Hope i gave you all the info I was supposed to.
On a BBB question - doesnt bleach have a really high pH (thinking back to my chemistry classes years ago) and doesn't that raise the pH of the pool? Wouldn't that be a bad thing? Thanks again!
