    Alt OCLT method??

    So, I need to do an OCLT. I HATE having to get up before sunrise!! Did I mention I HATE having to get up that early!? 😖 If the point is to see if FC drops in the absence of UV light, it got me thinking: would it work to take a pool water sample in a water bottle, place it in a dark place (a...

    BIG pool build!

    An aquatic sports center is being built near us. I’m guessing this will be Olympic size? Check out the pipes for the main drains! 😲

    Critter issues

    I’ve seen threads with owners posting about critters found in their pools. We have a new critter issue this time. Apparently, a pair of birds, Brown Thrashers, decided to raise a family in a bush near the deep end (equipment pad and walkway there as well). We opened the pool this week and...

    Forgot password

    How do I update my password if I’ve forgotten my current password? Normally, I have it set to stay logged in all the time on my iPad and iPhone. Somehow, I got logged out on my iPhone and cannot get in or reset my password (I‘m still logged in on my iPad) since I don’t remember my password...

    Alternate ways to add Cal Hypo?

    I’m starting to get ready for opening next month. This year has thrown me for a loop with back issues. I decided to go with Cal Hypo again for the initial opening SLAM (no issue with the added calcium). Finding fresh liquid chlorine can be a challenge around here and with my back issues I...

    Researching Replacement Pump Motors

    I currently have a 1 HP Hayward Superpump (model SP2607X10) with a single speed motor (1hp, SF 1.1). The original motor lasted 9 years (replaced June 2013). Next year will be 9 years on the current motor, so I figured I would learn about replacement options ahead of time so when it comes time...

    Squeeze last bit of life out of cell?

    My salt cell, a T-15 installed May 2015, is showing signs of wearing out. It’s reporting salt at 2800 and the Taylor drop test shows 3800. I inspected the cell and it looks clean, as always. It’s still producing FC and having no trouble keeping up with demand. Any tips for squeezing every...

    Mystery Ball Bearings in Pool

    I found several small ball bearings in the pool (size maybe 2mm or so?). They were a little tarnished, not shiny. My first suspect was my 8 year old Polaris 280 cleaner (wheel bearings?) despite the fact that it’s operating fine. I removed and checked all the wheels, but don’t see any gaps in...

    2021 pool pump efficiency requirements?

    Having recently repaired our single speed pool pump motor (replaced start capacitor), it got me curious about the new efficiency standards coming in July 2021. The reading I’ve done on this has been a little confusing at times, but this is what I’ve figured out so far (please correct me if...

    What to do with extra chlorine?

    Our pool pump motor was out of commission for a few days (needed new capacitor), so I bought some 10% liquid chlorine to keep FC up until we could fix the motor and restart the SWCG. The motor is up and running now. I still have 3.5 gallons of the chlorine left (date code 20 125). Am I better...

    Eliminate “Minimum” column on CYA/FC chart?

    I see so many posts all the time where pool owners are using the “Minimum“ FC number as their target, then don’t understand why they have issues when their FC is “fine”. It makes me wonder if having the “Minimum“ column is more confusing than useful. Has there been any discussion about...

    Turn off SWCG when adding cal hypo?

    This year, due to the Covid19 situation, I’ll be using cal hypo to SLAM our pool at opening (I normally use bleach). I expect I’ll might also use cal hypo occasionally during this season if FC needs a boost. The added calcium shouldn’t be a problem since I‘ve never add any since switching to...

    How to clean concrete?

    Our concrete pool deck is in need of cleaning. Shaded areas in particular are really dark (mildew?). Some years ago we cleaned it with a power washer, and while very effective, it left the concrete feeling rougher. Any suggestions for how to clean it in a way that won’t damage the concrete...

    Are these salt products the same?

    Hayward T-15 cell prices....ouch!

    In May 2015 I bought a Hayward T-15 cell for $398 (Amazon). I expect this season or next season I may need to buy a new one, so I checked current prices. I was shocked to see the price has increased to $600! I know generics are cheaper, but I prefer not to go that route if possible. I’ve...

    Pool leak, hire a leak detection/repair service?

    This season we seem to be losing more water than usual, about 1/2” per day. I did a bucket test, and after 24hrs the pool water level was was 1/4” lower than the bucket water level. After 38 hrs the difference increased to 1/2”. I know the past few seasons we’ve had a slow leak, about 1.5”...

    What brand/type of salt do you recommend?

    So a local pool store carried a brand of salt that I really liked, US Salt Superior Crystal, but now they’ve closed up shop. Everyone else in the area carries Aqua Salt, a brand I really dislike (dirty, mystery “stain inhibitors” that no one knows what it is). No one else around here has the...

    Ph drops over winter. Why?

    I’ve noticed every spring at opening ph has dropped from about 7.5 at closing (October) to about 7.0 at opening (May). Any idea why? At opening, I’ll bump up pH back to about 7.5 and it stays there all season; never have to add acid. The pool stays covered all winter; no chems added. It’s...

    Wetsuit ok in chlorine pool?

    I was thinking about how to extend my swim season. Heating the pool isn’t an option, so I wondered about using a wetsuit. I know nothing about wetsuits, so did a little searching online. Advice seems all over the place regarding wearing a wetsuit in a chlorine pool; anywhere from it’s fine to...

    Alternative to Bioguard filter cleaner?

    At closing I’ve been using this cleaner to clean the DE filter grids since 2004. Amazon.com : BioGuard Kleen It Filter Cleaner - 1 qt : Swimming Pool Chemicals And Supplies : Garden Outdoor It’s been working fine, but I wonder if there’s a cheaper alternative I can use (washing soda? TSP...

    Ok pool gurus and experienced owners, fess up!

    Time for you pool gurus and experienced owners to fess up to bonehead pool care mistakes you made! I’ll go first. ;) At opening when I started up the filter, water started spraying out between the upper and lower housing. I first thought it broke (its 14 years old), but soon realized I forgot...

    Home made liquid CYA?

    With the amount of rain we get during the season, requiring pumping out excess water, I usually have to add CYA several times a season. Adding dry CYA is somewhat of a pain, requiring running the pump longer than usual. I got to thinking, to make adjustments easier, what if I put granular CYA...

    Replacing gaskets in Hayward multivalve?

    Last season I noticed my multivalve (Hayward Variflo SP710XR50) was leaking just a little under the handle. The valve was installed in March 2004 and has never been serviced, so I figured it’s problably time to replace the gaskets inside. I found a few videos online about replacing the spider...

    Should I adjust TA?

    Gradually over the season my TA has dropped from 70 to 50 due to dilution from rain (had to pump out excess water on several occasions this season; not unusual for here). As usual, pH has remained very stable, 7.4-7.5, the entire season without having to add any MA. Is there any reason I would...

    Has PoolMath been updated recently?

    I noticed the recommended pH range has changed on PoolMath. It now says 7.5-7.8. I'm pretty sure before the low end was lower (7.2??). My pH stays rock solid at 7.4 all season (no acid additions needed). Before that was considered fine. But now PoolMath indicates it's low? Anyone know why...

    Help with Polaris 280 issue

    My Polaris is just a few years old and up until now has performed well. This season I noticed that it's not going into the shallow end much. When climbing the incline, which isn't steep, from the deep end to the shallow end I noticed it will curve to the right rather than going straight, hence...

    Why did pH drop over winter?

    I was discussing with friends my spring opening in progress and the question came up about why my pool's pH drops during the winter. Normally when I close in early October the pH is at 7.5. When I open in early May the pH is usually 7.0 - 7.2. Despite being covered with a solid cover...

    pH, TA, and borates adjustment order?

    I see on Pool Math pH, TA, and borates affect each other. So when adjusting, is there a preferred order?

    Which tests affected by high FC?

    I know the pH test is adversely affected by FC over 10ppm, but how about the other tests we normally do, plus borates via Lamotte strips and salt via AquaCheck strips (I use Taylor kits for everything else)?
