Tired of a green pool

[PoolDoc]

My bad; Carl's right => I should have looked at your dimensions.

Actually, those readings may not be bogus. The bogus ones look like this:
FC = 5.12 ppm
CH = 266 ppm
CYA = 109 ppm
TA = 115 ppm
pH = 7.42
and come from digital test strip readers that tend to get different results every time you stick the strip in the reader.

Anyhow, assuming the CYA levels are right, the "overdose" of chlorine was just right. Probably better add 5 gallons each evening, till you get a test kit. DPD tablets will NOT work for you, at the level of chlorine you need.

Be sure to brush, too. Algae gets in cracks and crannies. Brushing helps get it out, and expose what remains to the chlorine.

Thanks for the great advice everyone the pool is beautiful now. Had to hold back the wife who wanted to keep buying that pool store garbage they keep pushing on her (she is finally a convert now). BTW. I also did a lot of reading her about some of that stuff. Specifically phosphates, so here is a little of my anecdotal evidence.

We buy the bleach from the pool store since it is actually slightly cheaper than walmart, and more convienient in 2.5 gallon jugs. So why we are they we get them to test the water anyway. Just fun to compare what they say to what I read here. So last week they tell us again that our phosphates are high (500 ppb) and keep pushing the phosfree stuff. I ignore it and keep working the methods learned here. So finally yesterday I have the pool in what I believe is algea free. I pick up my bleach for the week, and get them to test the water. Phosphates are now 100 ppb. Never played with any phosphate stuff. So either getting rid of algea gets rid of phosphates or phosphate measurements are a scam.

Well, getting rid of the algae doesn't get rid of phosphates....

Glad that it's cleared up for you, and thanks for the update. If you'll take the time to be diligent about your testing and bleach additions, the pool should stay nice and clear for you all summer.

Happy swimming!!
