Green, cloud pool

[mcmillin35]

For 3/4 weeks now my pool is green, cloudy. Chlorine and PH is a little high. My alkalinity is a 10 of 100. If I raise my alkalinity with backing soda it’s gonna raise my Ph as well. Can I just throw in PH minus when I have the alkalinity at the right level. Will the high ph hurt the pool liner until I can get it down?

If you have algae, your chlorine is too low. The pool store test you posted isn’t going to be accurate enough to give good advice. Order a TF-100 or a Taylor K2006C test kit and post the results from that for advice. Until then add 5ppm of chlorinating liquid (ie “shock”) each day until your test kit arrives.

I’m not taking there advice. Just the test. We shocked , green- out and still My chlorine and PH are high but can’t get to kill the algae. I had ask a friend who knows someone in the pool field. Told me to add baking soda to raise the alkalinity. And the use ph minus to lower the ph. Will the PH hurt the liner until I can drop?

If you’re ph is in the 7’s your it is unlikely that your ta is 10. All of their results are suspect especially cya.
Any ph in the 7’s is fine. You don’t need to adjust it.
You need to do the
SLAM Process to fix your pool,
To do this you have to have your own test kit that includes all the necessary tests.
The Taylor k2006c and tf100/pro are the only ones that have all these. The slam requires testing fc multiple times per day & knowing your accurate cya
FC/CYA Levels.
Until you get one of those kits in & have accurate data to work with you should add 5ppm worth of liquid chlorine to the pool each day in front of a running return to keep things from getting worse- brush the area.
Use PoolMath to determine amounts.
In the meantime get those steps out & clean them inside & out & leave them out.

You will get lots of great info here, but it is easy to get lost in the various metrics and measurements, especially when you have a pool store giving you their normal inconsistent testing and nonsense advice.

If you have algae, your chlorine is too low, simple as that.
pH, TA, your filter, # turnovers, moon phase, etc. have no bearing on algae in your pool... only chlorine can kill and prevent algae.

If you look at my avatar, that is my recent chlorine test. Its much higher than yours and I would have a panic attack if my chlorine showed up at 5 or less.

You shouldn’t take their test either cause the results don’t make sense. Your TA and pH 99% can’t both be accurate. It’s hard to believe for new folks but it’s been proven time and time again that pool store tests aren’t any good.

I don’t know what green out is, but hopefully you didn’t add yellow out. Your pH is fine if it’s accurate. Your chlorine isn’t high if the CYA is really 15ppm( but we don’t believe it is)

test strip. Chlorine 5, ph 6.8-7.2, AT 40 ppm. Something keeping the chlorine from killing this algae. Thanks for the help

no way are those test results accurate
have you been using pucks to chlorinate
your ph is low if anything

Something keeping the chlorine from killing this algae.

It's called "too many cooks". You're trying to blend multiple sources of advice, go multiple directions at the same time, add chemicals that counter each other, and the results speak for themselves.

If you want to give our way a chance I can promise you that it does and will work. But it starts with accurate data to base the process and advice off of. It also does not mix well with any other advice. Not pool store advice, not "friend of a friend who works with pools" advice, just one process seen from beginning to end. It's up to you, we're happy to help but can't do a thing with unreliable data.

Can’t get the test kit you gentlemen recommend right. I will in the future

Yes

Ignoring the test strip part, and assuming we believe your test results of CYA of 15 and FC of 5, your low chlorine is the something keeping your pool from killing the algae.

Right now you are in the target FC range to prevent algae in a crystal clear pool. To actually start killing algae you need to be at the SLAM level, which is 10 FC for your CYA so you are only half way there.

I suspect your CYA is really much higher since you said you have been using pucks which contain CYA and Chlorine. Below is a quick chart I put together showing the various SLAM levels based on the CYA level.
