I've had the pool about 2 months. It took 4 weeks, but with the help of this board I turned the world's worst swamp into a Sparkling Oasis. Now, starting about 2 weeks ago, I start seeing what looks like sand in liner joints and depressions. But it's darker than sand, sort of brownish and maybe little yellowish. So I vacuum, brush, etc...it never goes away, but slowly becomes more prevalent. Then one day a week or so ago I see discoloration/sheeting on sloped part of deep end, and where walls meet in those slopes and and where slopes meet bottom. This stuff is less 'sandy' and puffs into a cloud when I brush it. It sort of goes away, but not totally. Then yesterday there is more of it. So I brush entire pool and run pump all night, add 1 jug 182 oz bleach.
Did drop test this morning and had 5.5 FC and 0.0 CC, but the junk is still there, just less of it. At first I thought filter was leaking dirt/sand back through but now I think it could be mustard.
Here are some specs from when I originally tested everything about a month ago (and it was crystal clear), except I've changed PH to what it is currently (was 7.2 at that time)
PH = 7.5
FC = 5.5
CC = 00
TA = 100
CH = 30-40
CYA = 25
I think I might be at fault, as I've tried to keep FC at 2-4, but sometimes it goes to 1, or even .5 or less (only one time). After I got everything clean, I quit running the pump 24/7 and do it 8-12 hours a day. I usually add 1/3 to 1/2 jug of 182oz bleach per day. That should seem like enough to me, but maybe I should be using more.
Do you think it's mustard? Should I start shocking hard and raise it 17? Wouldn't I have some CC if it was mustard?
Oh, and I was going to add 45 lbs. of Pro Team Supreme Plus - it should help prevent this issue - but should I wait until it stays clean for several days first, or would it help resolve it.
I'm thinking about calling home and having wife dump 3 jugs in then brush it this evening and do the overnight test, just in case it is mustard
Thanks.
I forgot to mention - it's been insanely hot here in the Deep South - upper 90's and triple digits - pool feels like bath water - maybe that's good for the algae but not sure.
