I've been slamming since we opened a swamp last week. No CC and we pass the OCLT but the pool is still cloudy/milky, not clear. Could this just be old algae needed to be filtered out? Hate to keep slamming if we don't need it. Thanks.
SLAM done?

Welcome to the forum if I havent said so. 
No, you need to be clear to be done. More filter time is needed.

Thanks for the welcome. My cc is zero and I've held 24 FC for a couple days by adding tiny amounts of bleach. Obvious passing OCLT. Just still cloudy. I can barely see the drains in the deep end.

Patrick ??
They are good with CC and they passed the OCLT so it's just a need for a lot of filtering to get the dead stuff filtered out.

Just hang in there, maintain residual for SLAM until you are clear. Once clear, you can let the FC drift back down. If you follow this, it won't rebound on you.
Thanks! When I backwashed today a lot of crud came out. So we've gotta be moving forward!!!

I like sand filters and I have one but from others posts they do seem to lag a little behind when doing a slam. It isn't uncommon for you to get below the .5 and your chlorine is holding but it's still cloudy
Just need to hang in there and you'll be sparkling blue shortly !!

The slam is NOT complete until your water is crystal clear. We know that can be a bit of overkill sometimes but we have often seen many folks let their FC down far too early and end right back up with a green swamp. It is not worth the chlorine savings.
So, The official TFPC stance is....
1. Your pool water is sparkling
2. Your CC's are .5ppm or less
3. You can hold your FC overnight without losing more than 1ppm.
Often, it is the SIZE of the filter rather than the type that makes the process slow down.....not saying that in your case but just fyi.

Thanks again. I guess I'm ready to get this thing done. Haha. I don't want to go back, so we'll keep it at slam level until it's clear.
I have a sand filter on my pool and when I had to SLAM, a little bit of DE added to the filter through the skimmer helped with removing a lot of the cloudiness.

I've done that too, just need to be careful about how much you use and make sure you don't get garden DE but something that's for pool use.

I'm afraid of DE right now. Haha. Baby steps. But you guys were right. I did another OCLT today just to see, we failed. Lost 4 ppm. Ugh...something is still there. Die algae, DIE!!!
:lol: :lol:
This is why we have the criteria. Don't worry, It will clear, I promise. Keep at it...
If all of the above are true, would it still be possible to have the slight appearance of green algae anywhere in the pool? (or any type of algae).
In years past I have had spots of black algae in my pool. I have some darker looking algae on the step by my waterfall. It could just be dirty/stained, I'm not quite sure yet as I'm not done with my SLAM, but this is why I'm asking. The 3 criteria don't call this out specifically so I don't want to assume (although I guess if the point is to kill everything, there really shouldn't be?)
