It means CYA is really low. Less than 20 ppm I think.
Do you have a 100ft tape measure to measure with?

Yes, that's the stuff. Use the sock method. We don't just recommend it for amusement. There's a reason: you could clog the suction lines, it's very acidic and rough on the plumbing when concentrated, if you need to backwash before it dissolves, you'll lose it, and it dissolves very slowly.Hobokenkitchen said:Thanks. So we need to start by adding CYA.
We do have CYA in powder form we bought last year. Is this what we need to put into a sock? It says to add into the skimmer or to mix with warm water and then add. I'm nervous to add too much. It says add 1lb per 4000 gallons which would mean we need bottles and bottles of the stuff. I dont think that sounds right?
My husband did all the sweeping and testing tonight. I think he just needs a push in the right direction and to be told that guessing quantities is not the way to go.
Hang it in front of a return. If that's not practical, tie the sock(s) to an empty chlorine jug or a pool noodle and let it bob around in the pool.Hobokenkitchen said:I remembered about putting it in a sock, but I don't remember where to put the sock. I'm assuming in front of a skimmer? Or in the skimmer?
Thanks so much for this guys - you are so helpful.
Last time we were messing with the pool I was heavily pregnant and then had a newborn. Now that baby is an 11 month old sweetie pie, but she's having some asthma issues so we're having to give her a nebulizer every 4 hours (including at night) for the next few days so we're pretty fried!
Nope. That's normal. It can take several days to dissolve. Giving it a squeeze when you go by speeds it up. Hanging it in front of the return lets it get pummeled by the return flow which also speeds it up.Hobokenkitchen said:This morning's chlorine reading.
FC: 9.5
CC: 0 (but we have to still have algae).
TC: 9.5
It doesn't look like any of the CYA has dissolved at all. Maybe the socks are too thick. May need to rethink.

The CYA gives off a cloudy white when I squeeze the socks. Is this normal/ ok??
linen said:That is normal. Get your FC back up. Once the cya is gone from the sock, assume that it is in your pool and adjust up your FC shocking level accordingly.
