This is what my pool looks like now. It was re-plastered in 2018. Just wanted to say read the directions and follow them for anything you add to your pool. This is no doubt one of my biggest screw-ups. I added 55 lbs. of boric acid to try to slow down the pH rise. (it didn’t) I brushed once and...

Hi all, Pool re-plastered in April of 2018. The mottling seems to have taken over in the last month. Is this something that can happen 4 years after re-plaster? I did add 55 lbs. of boric acid 6 weeks ago to try to slow down the pH rise (that’s another post to come) Also some of what I think are...

Everyones out of liquid chlorine so I'm trying to compare available amount in bleach. Get a little confused with previous posts. Home depot HDX chlorine shows 10% and 90% other ingredients. SDS says 10% by weight. Is this 10% available or less? When I put 10% in pool math it changes...

First off a big thanks to all the users and contributors to this site. Maybe I’m alone here but I never thought about testing for the salt level in my bleach pool. Always put salt at a 1000 in pool math. I used the strips and it tested between 6000 and 7000. That lowered the CSI over .2 which...

I'm adding 20 oz. 31% Muriatic Acid everyday. Plaster is only 2 months old and I realize the PH could rise for a long time but I'd like to try to see if I can stabilize it a little. I bought some Baking Soda at Costco (13.5 lbs for $6.59-good deal compared to other places) to bump it up but...

!st time owner of variable speed pump. Been running it @ 1000 rpm except when chemicals are added or using vac. Just noticed today that when I checked to see if there was any air in the filter it sucked air when opened. Ran rpm's up until water started coming out @15oo rpm. Does anyone know if...

Hi to everyone, I've seen on a few posts to get CSI close to +.6 for new plaster. My plaster is 1 month old. Seems high to me and pool math shows potential to scaling. To even get to +.3 I would have to max out on the goals on pool math. Is just being on the positive side ok for new plaster...

After many years of neglect I’m trying to make the back yard look presentable. Pool re-plastered & tiled. Had the flagstone "inside the pool" bead blasted to remove heavy calcium deposits along waterline. Sealed the flagstone in pool with 511 Seal & Enhance to cover the calcium that couldn’t...

Hi everyone, FC: 2 TC: 2 pH: 7.8 TA: 80 CH: 230 CYA: 20 CSI: +.15 I'm trying to slowly increase CYA to 30? with pucks then stop using them. Most posts say to keep CSI on the positive side for new plaster. Does that mean anything between 0 and .3? Please let me know of any adjustments needed...

Hello to everyone, Hoping to get some input on what kind & size motor/pump to purchase. Want to upgrade Pentair WhisperFlo 1.5 HP / 1.47 SF / 230 volt pump to a variable speed pump. Diatomaceous filter. One 2" return that goes to 3 eyeballs. Two 2" suction. One to skimmer thats connected to...

Hello to everyone, The black stains in the picture started coming 4 years after we moved in in 2001. No one knew what they were and I made everything worse by putting 3" tablets on them, dry acid in a sock, etc. Finally decided to get it re-plastered. 40,000 psi hydrojet to remove plaster. When...

Hello to everyone, FC - 9 CC - 0 TC - 9 Ph - 7.8 TA - 180 CH - 600 CYA - 70 Pictures 1 & 2 are from 7/2010. The 3rd is from today when I used straight acid with the Jandy stain remover. I had to keep it in place for a few minutes while it siphoned about 1/2 gallon of acid onto it. It seems...

I'm new here and hopefully my picture is attached. The stains have been there for years. The stain on top of picture with white circle is where chlorine tab was. The stain on bottom of picture is where I used dry acid in a sock. Can black algae get this big? Thanks.
