No. You don’t need to wait. CYA can take days to dissolve. Go ahead and SLAM based on the current CYA value (which is zero, of course). Then make adjustments as needed as your CYA climbs. Also, if you wait til the sun sets, you will lose less FC initially.

What Mr. Knauss said. You definitely need CYA. Also liquid chlorine is hard to find in some places right now. If you can’t find it where you’re at, calcium hypochlorite is a good option. You have some wiggle room as far as your calcium hardness is concerned.

I have had that filter and I have never once seen damage like that on the end. Yes, Pleatco is what you want for replacements.

Hello everyone! Been a while I know (please hold your applause and stay seated) but I have signed for a new build to start soon. Nothing to show as of yet. Details are as follows... 27,000 gallon IG gunite quartz plaster Intelliflo VSF with Intelliconnect Pentair CC520P filter HASA...

If you see no more green, your CC is 0.5 or less, and your FC is holding to within 1 ppm or less of loss overnight, then all you need is filter time and to maintain your proper FC level according to what your CYA level is. Dead algae is white and it can cause the water to look cloudy white...

Your ozone system isn't going to cause any problems, but the effects of an ozone system in an outdoor pool are negligible at best, simply because the sun is doing the same thing for you that the ozone system will do, albeit, much more quickly.

Welcome to TFP! Keep your filter running 24/7 and your FC at 16 or above until your water is clear, your CC is 0.5 or less, and you aren't losing more than 1 ppm of FC overnight. Right now, your pH is reading falsely high due to your FC being > 10 ppm. Don't add acid now. Don't worry about...

Welcome to TFP!

Welcome to TFP! How generous are you being with the silicone lube on your o-ring? You need to be sure that every spot on the surface of the o-ring needs to be lubed. Also, when you replaced the o-ring, did you purchase a Hayward one specific to your filter model?

Go with your readings. Your TA is fine at 70.

Well, you can SLAM now and then you may not have to do it later. Or, you can close in a week and SLAM when you open.

Good review. Thanks for posting.

Re: Young vandals sprayed dry chemical fire extinguisher in I doubt it will cause any severe problems. Just run the pump to filter things and keep tabs on your water balance.

Welcome to TFP!

Welcome to TFP! You should add 5 drops to check pH, not one drop. That should allow you to get a correct reading. An immediate pink reading on your TA test indicates a very low TA. You can raise your TA with baking soda.
