New member chicago suburbs - need quick help with Floc

[Annette_2206]

I just joined today and hopefully need quick help. My daughter's HS grad party is next Saturday. We have a 24ft AG round. Hayward cartridge filter. due to a new liner we had to drain & fill which is from a well. Everything was great, water was crystal clear until two weeks ago, high rain has caused it to go cloudy. Pool store recommended we "floc". didn't know much about it and went ahead and did it. Now after reading I'm concerned we made a mistake since our filter is a cartridge. I need clear water in 1 week, don't have time to drain, is this possible? Current test results below. Please help! thanks in advance...
FC 4.12
TC 4.12
Alk 145
PH 7.4
Calcium Hardness 314
Cyanuric Acid 75

Without a SWG, if your cya is at 75, your FC shouldn't be allowed to drop below 6. You should most likely follow the shocking process described in pool school. See the chlorine/cya chart there. Welcome!

If you are saying that you can't vac to waste....you can pull out your cart and pull your return hose off. I don't know your plumbing set up but that is what I did before I became a TFP'er. I just HAD to learn the hard way!

Wow, thanks for the quick welcome. since I already added the floc, we have the filter shut off. Can I shock the pool without the filter running?

Welcome to TFP!

Can I shock the pool without the filter running?

Filter must be running 24/7 when shocking the pool.

If you haven't already, I would suggest reading this article on The Shock Process.
