I discovered TFP last season and studied and tested and put it into practice with great success -- Thank you so much to all who helped!
I started my pool opening process a couple of weeks ago and am stuck.
PH 7.2 (it was 6.8 last night, added PH+, and got this reading 10 hrs later)
CYA -- too low to measure (which is interesting, because last season I made the mistake of shocking with packages of trichlor and my cya was about 100)
FC was 18 12 hours earlier.
I had to add about 15% of the total pool water with new well water over the past week, and the pool water is clear enough to see the bottom/walls just fine, but has a green/yellow tint.
My research lead me to a metals problem, so I got a qt of The Pink Stuff and added it about 14 hours ago. I can't tell if the tint has decreased.
The other possibly interesting fact is that my filter cartridge get clogged after about 12 hours, so it's pulling lots of stuff out. It's getting better (longer between filter cleaning).
So, here's my questions:
1) Does it sound like a metal problem or algae or chlorophyl?
1a) If metal, should I switch to Proteam Metal Magic? The reason I ask is because The Pink Stuff says it's not for iron and I don't know which metal is in the water?
1b) Does anyone know a source that can ship Monday using 2 day delivery? (can't get it locally)
2) I won't be at the pool for the next 4 days: Should I load up on clorox in the pool or use trichlor tablets to get some CYA in it?
3) Is there something I'm not realizing?
Thanks very much,
