    Can I treat mustard algae with CYA at 120 without lightening liner?

    The title says it all. Neglected the pool while not swimming in it this summer, and ran trichlor FAR after I should've stopped. (Pool has a slow intermittent leak; CYA drops over winter as water leaks and is refilled; during season I run mostly trichlor until CYA is around 80; repeat) I also...

    Does SLAM at 7.8 pH work?

    Would like to get through the rest of the season without buying any muriatic acid if pH level is no biggie. Vinyl liner pool, pretty sure I have a little mustard algae. Pool hasn't really been used too much the last couple summers, and this summer I was pretty neglectful - chlorine dropped too...

    DPD Powder is white but performs inconsistently.

    Anyone ever have DPD powder go bad while it still looks white? I'm getting inconsistent free chlorine test results. On several occasions I've gone to test chlorine and found it way too low, and added enough to correct. Then, testing the next day, I find that the reading is higher than it...

    Your help last year resulted in a 1 day open this year!

    Thank you TFP!! Closed last year after water temp was around 60, but then had to uncover and refill due to horrendous leak (~5" a week). Filled, got leak fixed (November in Kansas, IIRC). Bunch of leaves blew in, but pump was disassembled, so leaves stayed in. Covered up for winter. Took...

    Argh! Vinyl liner water down to 3-4 inches! MOSTLY FIXED :)

    I put the pool cover pump on the pool cover today (2nd time since pool closed). I thought the cover (resting on the water) looked a little low, so I put the outlet end of the hose under the cover to pump the water back into the pool. After the cover was pumped off, it still looked low, so I...

    When do I pump water off of the solid cover?

    We FINALLY got some rain here, soft gentle rain for a couple days now... in some spots on my solid cover, there's an inch or more of standing water. When do I pump it off? The instructions with the cover say to leave the water, that it will help hold the cover in place, but we're well above 62...

    How high can chlorine be when I close pool?

    I will be using a solid cover, and CYA is around 60... Can I close with chlorine at or above shock values? I've been running chlorine at/above shock levels for the last few days in preparation for pool closing this weekend, but I've just realized that since the water is much cooler, and sun...

    Anyone close pool without draining at all? (Cold Climate)

    First year with this pool. An acquaintance who has worked on pools for a living for a long time says I don't need to drain below skimmer/returns to winterize... mentioned a plug I could buy to thread into the skimmer that would aid in blowing out as well as accommodating ice expansion; blow out...

    Please educate me on types of pool covers

    New owner of an 18x36 vinyl liner 25,000 gallon pool in Kansas - hot summers, relatively cold winters. Previous owner says old winter cover was ordered too small, and IIRC it is also torn. It was the variety that used water bags to hold it, and was falling into the pool at the end of winter...

    How do I seal damaged threads on 2" pump housing outlet?

    After a long, drawn out fiasco with pool guys and pump motors, pump motor is replaced, up and running. Unfortunately, the pump housing was jostled when the pool guy installed the motor, and now I have a leak at the pump housing outlet. It seeps at at least one drip per second. It previously...

    Relatively New Pool Owner in Sunny, Hot, Hot Kansas.

    Hi, I got started on pool maintenance at another forum, thought I'd check this forum out. Water was suffering a little when I took ownership of this pool, but I feel like it's been under control for a couple months now. I don't have much to offer here yet, but I'm getting there. Thanks in...
