    Dead and flickering light- what are my first troubleshooting steps?

    All- Merry Christmas Eve! Noticed the other day that, of my 3 lights, one is completely dead, and the other randomly alternates between being off and flickering lightning-quick through some/all of it's color combos. Aqualink PDA P8, and BlueSquare Spectrum 360. Pool is ~2 years from being brand...

    YAA (Yet Another Aerator)

    Title says it all! Plastered and filled 3 months ago or so and alkalinity keeps climbing and the sheers aren't doing enough to let me keep up with dumping in all the acid I need to dump in. Have it on the booster cleaner port (unused since I've got a robot) which is still plumbed in.. PB...

    Just some Memorial Day messing around- RPM vs. GPM vs wattage

    All- Just enjoying our new pool, still trying to find that sweet spot of speed where the heater still has no issue and the sheer descents still look good. Slapped in a shiny new Blue White F300 in a very long straight pipe run after the filter, and took some initial measurements: RPM...

    Price of chlorine (and Home Depot liquid)

    So I was without a pool for 2 years and... oh my goodness. PB finished their new build 7-day maintenance; salt system doesn't turn on until 30 days after fill, and I had to make an emergency run to the corner pool store, and I laughed in their face when they rang me up. Then I realized they...

    Aqualink PS6 installed instead of P8

    Hello! Have a brand new build going; we just filled and PB came out to get pump circulating for startup. Tech realized we had a PS6 installed instead of the P8 we signed for. He went ahead and flashed it to the non-spa version because, well, we don't have a spa :) I'm not super concerned...

    New build- Dallas, TX

    All- Looking for some opinions on this one- we're about to start digging, and the PB came out for one last inspection. The house is new construction, and we've got some grading that is a little more pronounced than when we knocked down the previous house (the back yard was mostly concrete...

    Why doesn't a salt pool require additional salt?

    Getting ready to start new construction, and going with a salt system for the first time. Everything I'm reading says to get the salt concentration to the appropriate level, and then you don't generally need to add any (outside of splash out). Is the salt usage extremely low in providing the...

    M600, Marina, and warranties

    All- When I bought my M500 a few years back, I remember hearing/reading that if you didn't buy from a listed Maytronics dealer, you got a 2-year warranty instead of a 3-year. Now that I'm back in the market for an M600, I don't see anything like that as far as I can tell. Is this still a...

    Robots- any alternatives to dragging the cord across decking?

    All- I've got a new pool build in the planning stages; I've had a robot in the past, with the outlet on a wall 8' or so from the pool edge, power supply mounted on the wall, with the cord dragging across the ground/decking to get to the pool. I'm in Dallas, and keep the robot in year-round...

    New Build in Dallas

    All- I had a prior thread started quite a long time ago; wanted to start a new one as 1) a lot has changed and 2) we're finally nailing down a contract. Using a local, large PB we've used in the past for reno work; we're building a new home and the builder will GC over the PB (we're not...

    Preliminary specs for a new build

    All- Hello! We're moving again- we'll be gutting a house, and having all the fun of designing it like it was brand new construction. Still in Dallas. There's a decent-sized backyard that we're going to pulling a very large tree out of, cleaning it all up, and putting in a new pool. Right...

    CYA disappeared

    All- I know there's something about bacteria in soil that can reduce CYA; we used to have drainage issues in the yard and after a heavy rain, we'd have topsoil runoff into the pool and I'd have to add CYA back. Fixed the drainage, and, in general, CYA stays stable, though it usually gets down...

    Replacing the mesh on a Dolphin robotic filter

    Hey all- my second set of "spring" filters for my Dolphin m500 (the ones with the fine mesh, not the cartridge filter media) has ripped on me. This time around, I'm thinking I'm going to glue on some replacement mesh material- no sense in throwing away a lot of cash on another set. Any one...

    Costco bleach prices (alternate source in Dallas?)

    Man. I remember just a few years ago (ok, maybe more than a few) it was in the $7s for the 3x 121oz of 8.25%. Then it was in the $8s. Then, maybe 2 years ago?, it was in the $9s and it fluctuated up and down in the $9s a bit. And it's $10.59 today (this is in Dallas). Holy cow. Anyone...

    Replacement float for BlueWhite flowmeter

    Have an F-300 flowmeter, and, long story short, was a little careless when I was trying to flush out some sediment that got in, and lost the float (the "old style" stainless float). BlueWhite wants $24.58 plus $10 to ship :( I can get a brand new one, new style (red plastic float), for $63...

    break in underground pool light wire

    We've got two incandescent pool lights (in gunite); we had a gas leak earlier in the year and half the yard had to be dug up to replace pipe. I didn't realize until months later that a light line must have been hit- switching it on trips it's breaker immediately (we don't use the lights that...

    m500- partially running- impeller problem

    My just-over-3-year-old (aka out of warranty) Dolphin m500 is having some issues. The lights on the control unit behave like I'd expect them to- just turning it on, or cycling through the three programs, everything looks correct. But the cleaner won't move (that's not exactly true- every few...

    stenner injector- water coming out in reverse

    I've had a bleach injection setup for a number of years, with the stenner injector after all the equipment, in the top of a horizontal pipe just before going back into the ground at the pad. Nothing's materially changed recently. I noticed liquid dripping out of the output side connector of...

    How do I keep leaves from blocking my overflow drain...

    I very consistently have an overflow problem with my pool. We've got shrubs around it, and trees over it, and rain and wind always cause at least a few handfuls of leaves (or pollen chunks or other floating goodies) to land in it. And they go straight to the overflow drain and block it. when...

    Scrubbing DE grids with a soft brush

    It's that time when my grids need a good TSP soak. Has anyone ever tried a (soft) scrubbing with a soft-bristled brush to accelerate the process?

    Dallas, TX- pump rain water through DE sanitary sewer pipe?

    All- So I've got a yard drainage problem. Specifically, whether the house was built this way or got this way through erosion/shifting over time, I've got a low point in the yard where I collect an awful lot of deep standing water after a storm. There are some yard drains but the pipes have...

    Looking for advice on a new pump timer

    All- My current set up is: - 2-speed pump with the mechanical toggle speed switch on the back, on a simple Intermatic digital timer with freeze protection - Dolphin pool cleaner (on it's own power supply and timer) - heater (turned on and off manually; no outside wiring, so I need to make sure...

    Will a Polaris robotic 9550 climb a right-angle wall?

    All- Currently running a 3900. Two years ago, when we had our pool resurfaced, we had some steps put in, spa filled in, etc., and now a good third of the floor meets the wall at a sharp right angle (I didn't think about the curved floor at the time to accommodate the cleaner, nor did the PB)...

    replacing grout at deck/coping line

    Hello all! 2 years ago, we had our pool resurfaced, and part of that job was cutting out a width of the cantilevered deck and installing stone coping. Previously, with the soil expansion and contraction in Dallas, there was a seasonal gap at the grout line between the decking and the tile as...

    temporary drain and fill "discolored" my plaster

    Specifically, my pool was resurfaced with pebble sheen (Riverbend Sandler's version of it here in Dallas) a little over a year ago. I don't remember the color name but it was a blue-colored plaster between the pebbles for an overall bluish look. I did a partial drain and fill (got it about...

    "cloudy water"

    So here in Dallas, we got massive amounts of rain through May. My backyard was frequently flooded and I got an awful lot of overflow from flower beds into the pool (I've never seen a skimmer full of tiny snails until now). Was only checking my FC, pH, and Alk for several weeks, and then as of...

    FNS Plus 60- small grid bending to fit and lower positioning grid fit

    Just bought and installed a new set of grids for my FNS Plus 60. Two things that always bothered me that I finally got around to asking... 1- the small grid needs to be forced into a bended position to fit. Specifically, the upspout is in the position the small grid needs to be, so to make...

    Any mods out there so pool cleaner can navigate right angled walls?

    So we recently had our pool resurfaced, and part of that was to knock out a spa and put in some new steps as well as knocking out some old steps and putting in a tanning ledge. Not thinking about it ahead of time, a significant portion of the pool wall is now forms a tight right angle with the...

    Staining(?) tile grout

    All- Recently finished a pool resurface. We went from white plaster to a blue pebble. Along the way, all the white hardware (eyeballs, etc.) got switched to black. We had a round grate in the middle of a tile covering an overflow line. It got switched to a black rectangular grate. The...

    Possibly painting a Cooldeck...

    All- So my pool resurface recently finished- however, the PB left an assortment of "stuff" on the decking. When they came to clean it up, there was some uncertainty around if it was bond coat splatter, gunite splatter, grout splatter, etc. There's actually a variety of crud, I think more so...
