I have an 18' x 48" Intex Ultra-Frame pool - Intex SWG Filter

It has been up three weeks and I started having some issues with cloudy/slimy water. I came here and posted a question and found out I was supposed to have used some chlorine or bleach when starting it. We did the SLAM and I received by K-2006 test kit.

The water is now clear but when I add the powder to get the FC it does not turn pink at all. I also tested for CYA and the black dot at the bottom never goes away.

I am assuming according to pool math I need to get the CYA up before I will even read a correct FC level, is that correct? Once I get the stabilizer to the proper level should I slam again or just run the SWG?

I'm sorry I don't have the other readings with me but they are all okay. Just the FC and CYA are non-existent.

Thanks in advance!
 
No pink means no FC and if the black dot doesn't disappear then it means either no CYA or very little.

Assuming that is the case you may need to SLAM again but I would get some bleach in there and work your CYA up to 30. You could always do an OCLT to find out whether you've avoided the need to SLAM.

I think you should increase the CYA to 60 first. Now yours is zero, the FC is burnt out quickly.
 
Yes, you need to add enough stabilizer to bring your CYA level to 70. Use pool math to figure out how much to use. Put it into an old tube sock and hang it in front of your face return to dissolve. You can squeeze it periodically to speed it along. Don't dump it directly into the pool, as it will sit on the bottom and fade your liner.

Wait a few days before testing for CYA again, as it won't show up immediately. But proceed as if your CYA is 70 from this point.

Add enough bleach to raise your FC to 9-10, checking it daily and adding more as required so that it never falls below 9. Increase your SWG runtime as required until FC remains constant. As the CYA kicks in and begins protecting your chlorine, you should begin to see the amount you need to add daily decrease, and your FC should become more stable. Your SWG should be able to keep up with your daily burnoff.

Gotcha thanks, that is what I thought! The water is clear and pretty (for now). Should I go with the liquid or powder to get a quick CYA boost? I do not have a skimmer and the last time I used it, I just tied the bag on the ladder (powder).

Use liquid if possible. All solid forms of chlorine contain stabilizer that must be accounted for when calculating how much to add to your pool. It's simpler just to avoid them and add only exactly the amount you want.

If you're independently wealthy you can buy the liquid.... although it's really more like a gel.

The granular stuff will dissolve pretty quickly if you put it in a hole-less sock or nylon and dangle it in front of a return jet so the water flow pummels it. Rig up a broomstick or something through the pole slots to position it. I know I just saw a picture the other day, let me hunt...
