    Just came back in from my morning check. Even with the cover on, I could smell the chloramines. Some people say that chloramines smell just like bleach from the bottle, I think they need to do a comparison smell test. That would open their eyes, quite literally! The two don't smell anything alike, at least to me.

    Anyway, on to the results:

    FC=47, so dropped 3 overnight. The results posted last night were the final, about an hour after I dosed and covered the pool.
    CC=1, so combined with the odor, means I'm hopefully getting a handle on this, finally!
    No need to do a pH test, wouldn't be accurate anyway, with the chl level.

    I guess I'm going to have to take it to +shock+ levels. Still losing 3 - 6 ppm overnight. Either that or use some other algacide.

    This stuff just won't go away!

    I've been keeping cl in the 30+ppm range for about a wk. According to the Best Guess Chart with a CYA reading of 40. I give up on getting rid of it totally. I'm taking down the pool in 10 days and will just keep my cl at 30+ until I drain. When it's time to drain I plan on draining halfway maybe a bit more and adding an algacide, letting it sit for 24 hrs. to make sure anything still growing is dead. Finish my drain, scrub, dry and pack.

    Strange thing: Since I started using this solar cover my cl has increased by 1ppm daily. I haven't added anything since Tuesday! My CC is still at 0.
    No increase in the algae either. The whole situation has left me shaking my head.

    RedwingT,

    Sounds like a plan. Wife wants the pool kept open for a few weeks into September. Her sister will be in town, and we will still have swimming weather at least until then.

    So I'll at least keep the algae to a manageable level, until S-I-L is gone.

    To all Mods -- Thank you so much for being here with common sense advice for this pool noob. I really don't know what I would have done without everything you guys do to help people like me. I've learned so much here! I am now absolutely certain that next year will be so much better. Your advice about the K-2006, and Unicel carts is RIGHT ON THE MONEY! Keep pushing those items! (Now if I could change my siggy to show that I have the K-2006, and the 633EG pump, and Unicel C-5315 cart.)

    Re: Unicel Carts:

    Vacuuming through the filter with the Intex, blows a lot of the fines back into the pool. No so with the Unicel! Definitely worth the extra cash for them. One note though -- Intex has apparently changed the end hole sizes on the B carts to match the A & C carts. Makes it a pain to install the Unicel carts, as the end holes are 1/16" smaller than the Intex. However, once installed, you KNOW there isn't any leakage around the stubs in the case and lid.

    With the change from the 637R to the 633EG, comes a better system. The 637 is a suction filtration set-up, meaning the water goes through the filter before the pump, while the 633 is more like industry standard of pump through, so you get a pressure feed to the filter.

    Finally. Measurable CC level. Could it be the first round took care of the more noticeable green algae, and left what would appear to be mustard algae to take over? I've had to bring FC up to above 70 before I could get any apparent action.

    This morning, first test FC 48, CC 0. Dosed with 1/3g 6%. Second test 1.5h later, FC 52, CC 0. Dosed with another 1/3g 6%. Third test 2h later, FC 64, CC 2. Dosed with another 1/3g.

    It could be either the WM bleach has been sitting in the warehouse too long, or it is being eaten up at a rather high rate. I would have expected a lot higher FC with these doses. However, I now have a very strong CC odor around the pool. As noted earlier, NOT the same odor as a newly opened bottle of bleach, even given the highly concentrated vapors from the bottle.

    I just hope the FC can return to normal before mid Sept, when S-I-L arrives.

    Either I'm not testing right, or I have one heck of a chlorine demand. Just tested, right before vacuuming, results showed FC 48. Another 1/2g of bleach added after retesting to confirm the results.At this rate, I'll have gone through 6 g just this weekend. Oh well, bleach is cheap compared to what a pool store would be doing to me!

    If I could, I'd drain it and try again next year, but not my decision.

    Another pair of anomalies noted. My TA has been dropping, is now down to ~70, and I'm seeing a lot of small air bubbles coating every wet surface. Are these normal for running close to +shock+ levels? Or are these a byproduct of the algae being killed?

    Ok, another huge drop overnight. FC went from 75 down to 62 this morning. So I guess I must be doing something.....

    Ok, got word from S-I-L that she's not going to have time to play in the pool, and others from her family aren't going to be making the trip for the family gathering. So I now can go ahead and drain the pool.

    I'm going to let the FC level drop below 35, before actually draining.

    I'll take the water down to 3"-4", heavily dose the remainder with bleach, then scrub the heck out of it. Also will be trimming the algae hiding excess flaps of liner seams from the inside of the pool. I do have a question, since I am taking the pool down, should/could I use a copper based algaecide in the clean-up?
