Where is my FC going if the CC isn't on the rise? Are the high levels of the SLAM keeping the chlorimates down?

Green pool, I'm losing faith in the fight!!

CC comes in many forms when created. Some break down quickly, some stick around longer. How long each type hangs around depends on lots of factors including UV light, pH, free chlorine level... I'm over simplifying as I haven't studied the chemistry enough but that's my best, if not complete or entirely correct explanation.

It makes sense. I've tried to give myself a crash course in the chemistry behind it but there are definitely a lot of factors.

Hi. Just quickly scanned through this thread. I have one question for you. Before you drained your pool, why didn't someone suggest that you plug your returns, put a drain hose on your pump, hook your vacuum up and suck out all the green algae on the bottom of your pool first? Dumping fresh water on a blanket of algae or stirring it up with a brush is counter productive. Just a question. It would have made your process much easier and less time consuming.
Welcome to TFP!!!Well, to plug the returns is not trivial as anyone in warmer climates does not likely have winterizing plugs. And it sounds like you are talking about potentially cutting the plumbing coming out of the pump to try to hook a hose up ... that is not trivial either. The SLAM process works ... regardless of what the water looks like.
To ease your mind joegus, I spent the first half hour or so of the "drain" vac-to-waste, in the pool with flippers and goggles, finding every green spot I could suck up lol.

In a pool that's adequately chlorinated, CERTAINLY NOT. It's essential. If left to their own devices, I think algae prefer to cling to surfaces and are then able to form biofilms that protect them from chemical attack. Stirring them up and brushing them off surfaces exposes them more readily to chlorine. In a pool with zero chlorine it may be at worst UNproductive but even then it prevents biofilm formation.
Test #20
SLAM = 16
FC = 15
CC ~ 0
Little over half a bottle going in to keep it up.

If your cya is 40 then take it to mustard algae shock level 24? (ck pool math) and hold it for 2-3 days and watch it clear.
I'm going to wait for more input on that one downlo

Nothing wrong with taking FC to mustard shock level. Give it a shot and lets see what happens.
The only reason the recommended FC slam level is to keep the process as economical as possible.
downlo had a good thought about maybe some mustard tho... certainly wont hurt anything.
Keep that algae stirred up too. There is definitely an improvement by those 2 pics.
