0 FC, 0 TC, but otherwise ideal?

So I realized 2 days ago that our outdoor plugs had tripped from a lightening strike on Tuesday.
I got the SWG & sand filter working, added more salt cause it was a bit on the low end.
Cycled the filter for over 24 hrs and tested.
All readings are in ideal range except the FC, TC are both 0.
should I add bleach to get back in range? I'm a bit confused since it's a SWG pool...

Yes please add bleach until your SWG can maintain the level. Use PoolMath to get the correct amount of bleach to add.

What are you using to test the water? Some kits bleach out and will show 0 when it's actually 10+

I'm using the TF-100 for testing.

You can *always* use plain household bleach to increase your FC level. I use it in conjunction with my SWG when I want an instant rise in FC...for example before or after a big party or when my grandson pooped in the pool.

I like to consider it my behind the scenes safety net, its always keeping my water at a safe baseline but knowing that SWGs have a certain lifespan (x amount of hours) I limit the wear and tear on mine when possible.

This is a classic example of SWG use. They are fantastic for MAINTAINING FC in your pool but sometimes not so good at a sudden increase. Simply get to your desired level with bleach and then dian in your SWG to maintain it.
