Was a little green... now just cloudy...

Dougget · Sep 4, 2017

Hi,I let my FC to zero and left the pool covered for a solid week... opened it to find a greenish hue. My last three tests are as follows:

The FC of 7.5 on Sept 2 is a result of shocking with 2 gal of 12% chlorine the previous day.I need to get some stabilizer... but other than that chem looks good.Filter has been running 24x7 for the past 4 days. I've been brushing daily and just vacuumed this morning (couldn't see the bottom).How do I get back to crystal clear water?Thanks,Doug

You need to SLAM Pool School - SLAM - Shock Level And Maintain

How are you testing?

SLAM. Shock level and Maintain until you pass the OCLT. Keep brushing and vacuuming also. Run pump 24/7 and backwash after pressure increases by 20%.

you also need to put what kind of pool you have in your signature line - Just look at everyone else's. it will help the experts help you. rules are different for vinyl, salt, plaster, etc.

Are you using the TF-100?

I'm new. Hi everyone.

Hi all,
I just filled in my signature. I have a 19,400 gal, IG vinyl pool and use the TF-100 test kit.
I'm looking at the SLAM instructions now...

Thanks,
Doug

Well, I did the SLAM and now my chemistry is right on (except for the stabilizer) and the pool is still cloudy.
Very frustrating. What's my next step?

Thanks,
Doug

Keep SLAMming until it's clear. The cloudiness is dead algae that needs to be filtered out. Keep your chlorine at shock level until it passes OCLT and pool is clear. It takes patience... you can also add some DE to the sand filter as you slam and it helps trap the particles faster.

How about adding some clarifier? Description says, basically, that it lumps the dirt and dead algae together making bigger particles which are easier to vacuum/filter out.
Is that worth at shot?

Also, because my CYA (Stabilizer) is low, my shock level is also a fairly low FC. If I'm reading the table properly, my Shock FC level is 10.
Is the right?

Thanks,
Doug
