Spring startup with SWG

[Quickstep192]

I installed my SWG mid-season last year, so there was already chlorine in the pool and all the SWG had to do was maintain it.

This year after re-filling the pool, I’m starting with virtually no chlorine. The water is clean and clear thanks to my solid cover.

How do I establish the chlorine level when starting from square 1?

I’m thinking I set the SWG to 100% for a while until FC hits the level I need.

PS, I’m leaving the cover on so the chlorine doesn’t burn off faster than the SWG can make it while it’s playing catch up.

Add liquid chlorine to get to your target level FC based on your CYA.

That's one thing. But you don't want the water unsanitary and/or growing algae in the meantime.

Anytime you get close to minimum, 'now boost' it with LC.

OK, let’s assume I should SLAM it with liquid chlorine. I’ve only used granular shock in the past. How much Liquid chlorine should I put in a 15,000 pool?

Download PoolMath.

Set up a couple details about your pool, like the volume to get the app going. Then a bunch of tabs pop up such as 'FC'. Click on any of them to enter your start value and target value. Then scroll through the additions for the one you want to use. In this case, bleach, trichlor, dichlor, SWG, etc. Once that's selected it will tell you on the bottom to add 1.7 gallons (etc)

Sorry if these are dumb uninformed questions but…

After running my new Intelliflo3 at 1/2 speed and the SWG at 80%, my chlorine level has reached 4.0 The water is clear.

Should I still slam as part of spring startup, or is the SWG enough?

No question is dumb or uninormed.

Perform this test...Link-->Overnight Chlorine Loss Test

Cheap, simple. You pass, no slam.

You don't pass, then follow this process...Link-->SLAM Process
