My first rookie mistake

[Pmachang]

Hi forum.

I moved into a house that had a pool a month ago and everything was going well until I decided to add more shock that I should have.

now my readings using Taylor test kit is as follows:
FC: 14
CC:0
PH: 7.8
TA: 100
CYA: 70

For the time being, I have turned off my SWG and hopefully with the sun and the kids swimming, it will burn off some of that FC.

is there any harm to have the kids swimming with such high FC? Is too much FC bad for the pool?

Thanks

No problem. With a CYA of 70, you can be in the water with an FC up to 28 per the FC/CYA Levels. Let them swim.

Thanks Texas Splash for your quick reply.

Where do you see 28?

I looked at the FC/CYA chart link and I only see for CYA=70, Target FC=8-10

Where do you see 28?

It's on the SLAM tab.

Never mind - I found it.

I have CYA of 60 and with an auto cover and SWG, if I don’t pay attention, my FC at times drifts into that range. Just let it drift down. It is no problem and it is safe to swim. You are much better with your FC at the high end rather than close to the minimum. Don’t let it get there.

Welcome PM !!! For any easy reference without the chart, swimming is safe up to SLAM level for any CYA, Which is 40%. So if you notice the CYA drops to 60, pull out your cellphone and know that 24 is SLAM. Your SWG will probably over produce at times as the season winds down. So you’ll catch it at 12 (?) and have to dial it down a hair.

This is a great time to learn because you’ll get caught with too much (but totally harmless) production and by the time it goes the other way in the spring, you’ll be an old pro.
