    old pool new member.

    I am caring for an old pool, Parents 93, fired the pool service, shocked with diclor and brushed to rid of green algae then I found you. I have been using pucks to chlorinate but I will now change to liquid. Water is clear now, algae gone and test kit arrived yesterday. Readings today temp 68 f, FC 7, CC 0, Ch 725, TA190, CYA 150, fill water from hose PH 7.5, CH 400, TA 180. Used poolmath as best as I can figure out how to use it and it said replace 73% of pool water and I need to add 1 QT 2 cups MA. Pool drain is plugged I think and am presently digging up skimmer line looking for air leak. Have found and fixed 1 leak and can now use the auto pool vac and am able to keep pool clean. I would like your opinions and thoughts on this. Changing water will be a challenge.
    Thanks Howard

    Welcome to TFP!!!!

    How did you get the CYA of 150ppm? Clearly you need to replace a significant amount of water to get the CYA under control.

    You did not list the pH for the pool, but I would likely start with replacing water.

    Easiest to buy a cheap submersible pump (Harbor Freight) or rent one to do the draining. In AZ, you do not want to leave the plaster exposed to the sun without water for very long at all.

    If replacing water is prohibitive, try Calsaway. They can do Reverse Osmosis on the water. The website says they serve Casa Grande, which doesn't look too far away from you.

    Ops. PH 7.8 sorry. I'm getting old. Thanks for quick response. I have started searching for rental pump and have found one in Casa Grande for about $55 a day 4320 gph. 50 miles round trip. Will read up on Calsaway when I get more time. Thanks for the suggestions, they helped.

    jblizzle I got a greater than 100 cya reading on first test so I diluted mix 50% and retested and got about 75 and doubled for 150.

    Sounds like you did the CYA right. Replacing water is going to be a good bit cheaper than RO.
