Shocking the pool...is my FC gonna be too high to swim in?

[Rockadile]

I am opening my new pool and this is all new to me...still trying to figure everything out. It is SWG and I need to shock it. The CYA level is 75 and I am looking at bumping the FC to 25-30. My question: is this too high to swim in?

Thanks.

I feel that any FC level below shock level (based on your current CYA level) is fine. Indoor pool routinely run as far higher effective chlorine levels (because they have zero CYA). But you need to decide for your self what you are comfortable with.

I have been in my pool at 20-some ppm chlorine with CYA around 35 with no problem, but I wouldn't plan on swimming in it for fun. It would likely be tough on bathing suits. If you raise the FC, it will go down pretty quickly if there was a need to shock, like algae. Is there a reason you are shocking?

I am not really sure. When the pool company opened it, the water was pretty dirty (I couldn't see the bottom in the 3 foot end). They supposedly shocked it, but when I tested 48 hours later, FC was zero. I have been trying to get my FC levels up since as they seem to hover around 1ppm. I was trying to get them in the correct range before dumping in salt and firing up the SWG. I though shocking it would be the best way. Maybe I'll just dump the salt in and try to get that configured correctly.

We really need a full set of test results to advise.

I will say, however, that if you need to shock it is not recommended to use the SWG for that purpose.

Thanks for the help. I just had my water tested and it appears there is no need to shock it.

tested with your 2006 or somewhere else? what were the results?

I had the pool company test my water...I posted them in another thread:

While their number are a bit off in some spots, it doesn't appear that I need to shock. I think I am gonna focus on getting my SWG figured out.

Thanks.

Your FC level is way way too low for your CYA level. You need to shock the pool until you can maintain the correct FC level.

UGH! I am determined to figure all of this out. Thanks!
