Thinking I should have put this in the Algae Section. Mods, feel free to move if it will help keep the boards cleaner. 8)
Hello. I'm getting around, I'll tell ya!
My SIL just took her cover off her 27x5ft round aboveground. I figure her gallonage to be 21,400. The water is pretty clear except for a layer of algae on the bottom and sides.
Here are her readings via the TF-100 <hang onto your keyboards>
pH 4 <I'm guestimating because the color was lighter than 6.8 and almost looked to be the color of 1ppm chlorine on the other side of the test vial for the chlorine>
TA 10 <changed to purple and took 1 drop to turn pink>
CH <didn't test>
So I know I have to get the pH up right away! I hope to do that tomorrow as soon as we get the pump running. It needs a new hose that goes from the pump into the sand filter.
Pool Cal says I need:
1,474 oz of Borax to get to 7.5
452 oz Baking Soda to get to 100
114oz CYA to get to 40ppm
I picked her up one 4lb container of CYA that I'm gonna add as soon as I get the pH and TA in line.
I'm gonna assume that it will be safe to add 6 boxes of Borax and 7 boxes of Baking Soda within minutes of each other or should I wait a half hour for each? <Note: I'm not adding all the borax at once, I actually cut the amount of 1,474 oz in half and got about 6 boxes to start off with> <--- Does that sound okay to start? The 452oz of Baking soda comes out to 7 4lb boxes which I didn't cut in half.
They want to try and have this pool ready by Sunday for a birthday party. Here's my plan... tell me if it will work. Top the pool off. Throw the hose in and vac the bottom to waste since they have a sand filter. Refill and add chems. Will it shorten the shock process getting some of the live algae off the bottom first before we shock cuz I know it's gonna turn milky white once we start killing it. I also plan to add a cup of DE to help filter it out faster. What do you think? Am I on the right track?
