    SLAM progress help

    So here I was thinking I was doing so good. I started slam on thursday, pool green as can be, definite algae growth. Have been going by the book as far as I can tell. Got my CYA up to 50 during this process (overshot 40 :/)

    Did the overnight check last night and lost .5 FCl and had .5 CCL. I thought man I'm there! The water was clearer but still seemed a little, and I mean a LITTLE cloudy, just a hint. So continued through today. This morning at 5:30 had FCL 21, CCL .5.

    Went to soccer practice for the kids, checked again at 1pm, FCL 10, CCL 2. uh oh.

    Upped it to 20, checked again at 3:30, FCL 20, CCL .5. Seems stable.

    Checked again at 7:30 and dang it if it wasn't back down to FCL 10, CCL 3.

    Water is very clear. Am I being impatient or do I have something going on? I pumped 330 oz per instructions to 20 so I guess I will keep going. Is this big of a FCL swing normal with the water looking as good as it is?

    Re: SLAM progress help

    Did you take your steps out and clean them? Do you have a light?

    No light but did take steps out, they have been out the whole time. I have a pretty simple system, skimmer and 2 returns.

    Re: SLAM progress help

    Have you retested your CYA? Since you have recently conditioned, perhaps your levels have risen since you last tested and your recommended shock level is actually higher.

    Re: SLAM progress help

    I got 50 twice but I will recheck. Also failed the overnight test. I went from 28 down to 24 FCL and 2 CCL. I over bleached last night because I had a bit of 8.25 bleach left and used it instead of the 6 I have.

    Should I take off return jets? I'm worried about getting in with that much chlorine. I have scrubbed them and can't see any visible signs of algae. I'm really stumped.

    Since you can't blame the sun for the overnight loss, there's still something organic in the water. If you can't see it in the pool, and it isn't lurking in the steps since they're gone, then it has to be in the plumbing. How long has it been since you cleaned out the pump strainer and the filter cartridge?

    Re: SLAM progress help

    I cleaned the filter out 2 days ago with cartridge cleaner. I also replaced the psi Guage since it was rusted out so was up close and personal with that housing and didn't see anything alarming.

    I also have opened the pump and cleaned that filter since I have had vacuum running a lot over past 2 days. Should I disconnect all the hoses and give them a good soak somehow?

    Re: SLAM progress help

    Maybe it is just the pic, it is hard to tell since there is nothing deep as a reference. But from what I can see, the water can be clearer. Here is the advice Dave gave me on my own SLAM thread:

    3. You can hold your FC overnight without losing more than 1ppm.

    Look at other pools on the forum and you will see you are failing #1....crystal clear water. Run that pump 24/7 and keep SLAMming until you get this...



    That's in 7 feet of water. Not bragging, just showing you that it's easy to do with filtration and adequate chlorine.
    His advice to me is the same I would give you: KEEP SLAMMING!

    Leave the hoses alone. They have plenty of chlorinated water running through them. Disturbing them is just begging for leaks. Since you only started on Thursday, it's a little early to be panicking. Maintain the SLAM. At least make sure there's no gobs of leaves in the pump strainer.

    Re: SLAM progress help

    Just a note: It is perfectly fine to go in the pool even with FC up at SLaM level. It's not like you plan to be in there for hours, and even if you were it would still be fine.

    Re: SLAM progress help

    Thanks for the responses all. I definitely do have a leak probably from disturbing the filter housing. So probably going to order new gaskets for all of that. I went from mid skimmer down to third skimmer in 1 day so it is going somewhere.

    Pic with depth for reference vacuum on bottom and 4 ft. Definitely not as clear as yours.

    Re: SLAM progress help

    Well considering I started with the below pic, I guess I am being impatient. I'm already out of FCL reagents so I have some more on the way. What should I do to maintain FCL until they come in? It might be Tuesday.

    Re: SLAM progress help

    The easy answer is, continue adding the same amount you have been. At worst you might be a little over, but that's better then being under...

    Yup, I think that shows you are not quite there yet. Keep slamming and you should be crystal clear in no time.
