    New to this...update w/pics

    Ok, here are the basics:

    Taylor kit

    Cya 100
    Ph 7.3 (1 drop to 7.4)
    Total alkalinity 140
    Calcium hardness 340
    6.2ppm free chlorine
    0.6 ppm CC (maybe up to 1.4 as every time I let it sit it started turning pink again)

    In ground pool with pebble tec type surface
    Approx. 30,000 gallons
    Pool is 90 degrees, has solar panels and a solar blanket
    Cartridge filter

    And we keep getting those darned green algae blooms! You can see we added chlorine, but now what? We even added the algacide 2 days ago. Arg...so frustrating.

    Algacide is only recommended as a preventative, not a killer. And it shouldn't be required in a properly maintained pool. Your cya is way too high for your level of FC and will require draining in 3rds to lower it to avoid those "blooms".

    Welcome to TFP and congrats for having a good test kit. CYA is high making it harder to get rid of the algae. I see a partial drain and fill in your future. FC is low for your CYA level. Read through Pool School and ask lots of questions. I've seen MANY a green monster slain on this site.

    Yep, you have yet another case of sky high CYA, we are seeing many cases every day around here lately, which is somewhat surprising this early into the swim season.

    We are draining about 25% of our pool to start. I will retest again tomorrow.

    Re: New to this

    Ok...newest test readings

    Jun 4, 2014 Jun 5, 2014 Jun 6, 2014
    CYA 100 60
    Ph 7.3 7.2
    Total alkalinity 140 120
    Calcium 340 310
    FC 6.2 12.8 8.4
    CC 0.6 0.6 0.6


    Pool is still greenish. I am not sure how to get rid of the algae but keep the pool usable for the kids. It is supposed to be 100 degrees this weekend!

    Re: New to this

    You need to follow the SLAM process in pool school, for a CYA of 60 this will require raising your FC up to 24 ppm and maintaining it there until it is clear. No one should swim while doing the SLAM process, but also no one should swim with the way it is now.

    Re: New to this

    Now what? It looks clear, not losing chlorine at any sort of crazy rate, but the CC is still 1. Do I keep slamming until CC is .5?

    Here are last night and this morning/late afternoon levels:
    9:43:22 PM
    FC22.5

    6:48:22 AM
    FC23
    CC1

    5:17:11 PM
    FC20 (did not add chlorine all day and left the cover off)
    CC1

    Before:


    Today:


    And the deep end (8')...I think some of that green is actually the tree's reflection:

    Yes, continue to SLAM until you meet three criteria that determine when you are done. See red lines in my sig.

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Just wanted to make sure there was no other reason for CC not going down to .5. Thank you.

    I believe the CC test will turn pink of you let it sit for a few minutes. Don't wait for the results.

    You are likely getting close, make sure to scrub and look for places algae might be hiding, in recesses, under ladder steps, etc.

    Re: New to this...update w/pics

    Can someone please give me an idea of how long this takes? We have been doing this for one week as of tomorrow, chlorine was steady today, CC won't budge. I keep sweeping, it looks clear, but I do see some cloudiness when sweeping.

    I am getting a bit worried because we leave for vacation in a few days for a week. Ugh. I bought phosphate remover to use as a preventative while we are gone, but if I cannot get it balanced first will I lose all my hard work?

    Please update us with a full set of test results.

    Also, perform the OCLT tonight and re test in the morning at 5am and report those test results back.

    If you're going to be gone for a week, a metals-free algaecide like Polyquat-60 is a better option as preventative in an already clean pool. Phosphates are meaningless with adequate FC.

    I'd have someone add some bleach while you're away if possible. Trichlor pucks would be an option but your CYA is pretty high already.

    Re: New to this...update w/pics

    The frustrating part is I don't know how well I am testing. So, last night hubby told me FC was 21.5. This morning I finally stopped at 25. Here are some pictures (because I kip don't know how well I am seeing the shades of pink!).

    Does it look ok to stop slamming?

    Never mind, CC went up to 1 this afternoon. I guess i am still not done. It will be interesting what it does when we leave for vacation.
