Hi there TFP'ers! This is my first summer following the TFP method, and though my pool has been much better, I still have some problems.
My pool seems to have algae. It has a "smattering" of dark green silt on the bottom though the water is clear. I don't have a good vacuum. That is on my wishlist. When I brush over it with my "vacuum", which is really just a hose connected to a brush end that diverts the debris through a tight mesh bag, the "stuff' just poofs and spreads throughout the water. I keep bringing my pool up to shock level (or maybe even overshooting that number...tell you why in a minute), brushing, running filter 24/7, backwashing, and adding more chlorine, but this stuff keeps hanging around. I haven't bothered doing a OCLT in a while because I still have visible "algae"?
1. I'm not shocking at mustard levels...could it be the dreaded mustard algae?
2. I chlorinate at night, but how much chlorine should I be adding during the daytime to keep chlorine levels up at shock level?
3. How long should it take to kill the algae???
4. Could this be pollen?
Here are this mornings readings after starting SLAM last night.
I said I overshoot when I add the chlorine because though my pools capacity is supposed to be 7600 gallons, it has a bit less...not sure how much, but it's less because one leg really dug into the sand and sunk one side by a few inches.
5. Is it possible I'm totally reading my CYA wrong? I drop the solution into the tube until I cannot see the shape or shadow of the black dot at all...just cloudy white, but I have exceptional eyesight...someone else might stop dropping the solution in sooner and say they have a higher CYA number than I would.
6. What is the best light to do that test in? It seems to appear higher or lower due to more or less light?
Sorry for the barrage of questions...I'm hoping someone can shed some light on my problems! Thanks in advance!IMG_20160811_102822904.jpgIMG_20160813_092047516.jpg
