Yes. I am vacuuming to waste every other day. It is an apartment complex pool. I had the CYA at a perfect 30 ish, then the pool company came to open it, which is something I was already working on. The property manager relayed we drained down the pool and replaced a lot of water... Anyway...

While 26 is a touch low, it is better to be a little low than high. Your method to raise it with TriChlor is very good being 30 is a good place to be and you are already close I wouldn’t add CYA. Even if you overshoot to 40 or 50, you are still in the zone. 40 is probably the best place to...

Good Morning: Talked with our supplier today, and he can get us only 4 bottles of sodium hypochlorite this month. We have a budget of $150 per month for that pool. We have one pool at the complex at 100 ppm CYA. The other pool is at 30 CYA and chlorinated with TriChlor pucks, so it is not a...

I would also make sure your reagents are not expired for testing CYA because unless a lot of water was replaced from closing to opening this year perhaps the reagent is not making it cloudy enough to properly register all of it. CYA doesn’t disappear.

We actually did a CPO class a few years ago, and ironically most of it was measuring the size of pool and doing the math for adding chemicals. For example if 5 oz of XYZ-Chlorine is required to raise the Free Chlorine by 1 ppm for a 10,000 gallon pool, how much is required to raise the Free...

Thank you! This is very helpful information. I think right now it is right at 100 ppm, which is a LOT!

Okay.... I am vacuuming every day like we normally do... and like leaving the vacuum unattended for a couple hours to waste while I do early morning work orders. There is a system to automatically fill the pool when the level drops. We have the automatic chlorinator turned down to the...

I work for an apartment complex as a maintenance tech. We have Two pools in SC, and the Property manager okayed opening one pool for limited use, so I skimmed it, backwashed the filter and vacuumed to waste even though it is nasty water. At any rate there is some algae in that the water is...

Thanks Marian. I was looking at Pool Math and it actually says Dichlor will lower my pH even further, which is a bit scary. To be honest my comparitor goes down to 7.0 on the pH scale, and I am guessing 6.8. I don't have any Borax, but I have a whole 5 Gal Blucket of Soda Ash the pool store...

Also, I read that sometimes SWG read wrong when they are dirty and full of scale. You might want to read the manual about cleaning the generator, but usually it involves some sort of acid bath.

Good Day, A friend of mine just replaced his Vinyl liner, and we filled it with water. It holds a mere 7,000 gallons. Right now the pH is at 6.8, Chlorine 1, Combined Chlorine 0, Alkalinity 50, CYA 0, and Calcium 110. Being this is basically a plastic pool, the calcium does not matter...

Acid will lower your TA a bit too.... But it is a false low because as the PH creeps up the TA will too. That said your TA is perfect at 70 right now. When done fixing your PH test your Alkalinity... You might need a little backing soda, but target 70 again.

He is kind of old school... Their first certified pool operator, but he doesn't go on the Internet really. He told me the last maintenance guy got fired over the pool turning green and s couple other things... But that management expects the pool to open, be clear, and it to pass any health...

They are open year around but realistically people stop swimming mid November. He requested 3 days but management gave him a 48 hour maintenance window. They sent notices to 315 apartment units notifying of the upcoming pool maintenance. I told him to buy the FAS-DPD test reagents and the...

Friend of mine is running an apartment pool, which is a sparkling oasis... That said he knows he needs to drain some water because the CYA is high (slightly over 100). It is 70000 gallons and chlorinated with Trichlor pucks on two feeders. Two sand filters run 24/7. It gets Backwashed once...
