    Hayward spa light won’t turn off

    Hayward Prologic with Colorlogic lights (I think) To summarize, we had a power outage the other day, and my spa light won’t turn off. When I power cycle the lights (circuit breaker or service mode for 30 seconds) the pool lights (2) will come on as well as the system reboots/tests, the pool...

    Switching from pucks to liquid, thoughts and insights?

    Not sure if Pumps, Filters... is the right channel for this, but didn't seem to be another clear fit. As the title summarizes, I've had an inline Pentair chlorinator since install (pucks) and I'm considering/looking at switching this over to a liquid set-up. Wanted to get advice/insight from...

    Self-servicing Hayward heater... how?

    We're located in Austin, TX. Put the pool in about 4 years ago. Equipment includes an H400FDN Hayward heater, which we largely use to heat the spa year round (less heating in the summer, and pool rarely gets so cold you can't swim). I maintain the whole system largely myself with warranty and...

    Slightly higher pressure on brand new filters... normal?

    C-4030 Hayward Filter (I think... it's a 4 filter in ground system, but I often get the size wrong) Bit the bullet and replaced my old OEM Hayward filters with new Pleatco filters based on a bunch of research and $75 lower price. Haven't had them in long enough to review them, but running into...

    Pleatco vs Unicel, any recent experience?

    After a little under 5 years of dutifully cleaning my four filters every spring and fall I'm looking to replace the OEM filters for my Hayward filter. I could probably keep going, but the last time I pulled them they were pretty dirty in the core, and I think 5 years is probably a good enough...

    When do you Replace vs Clean pool filters?

    I've got a Hayward SwimClear pool filter, not sure which model but maybe C4030? It's got four filter cartiridges inside of it. I've had the pool in operation for about 4 years in Austin, TX, and I dutifully clean the filters about every 6-8 months. Basically I do it in the late spring and do...

    Temperature sensor replacement... how to determine?

    For awhile now my temp sensor has been throwing weird results. The control board doesn't show any error, but whenever I turn on the spa (we only use it for the spa here in TX) it will often get WAY HOTTER than the 97f I have it set to (kids). I also find it tends to swing from time to time...

    Super shocking for black algae, whats the final answer on swimming while you shock?

    I'm currently super shocking my pool, meaning I've been maintaining my FC around 30ppm for the last few days in an attempt to eradicate some annoying black algae that's been taking off in the horizontal grout under the waterline (I have glass tile on ledges and steps, and for some reason the...

    Freeze protect keeps switching to spa mode?

    I have a Hayward variable with a Hayward controller, can't remember the numbers off the top of my head but recent (2-3 years old). Our pool has a pool and spa on a single heater/unified system, with the spa farthest from the pad and the pool kind of lengthwise in between it and the pad. My...

    Limestone dust in pool... effects? Mitigation?

    Had our pool put in a couple of years ago, FINALLY got the pool builder to send the stone masons back out to fix some legacy problems from a worker who was too aggressive sanding/grinding the spillover stones (turned them into anything but squares). It occurred to me that the sanding and...

    Putting in an overflow at the pad... how to?

    So, when I put in my pool the PB never brought up the idea of an overflow system, and after some crazy rains here in Austin (and some overflow situations) I'm thinking of putting in an overflow valve. Looking to get some sage advice from folks on my plan. The plan is to put the overflow at the...

    Can't maintain Free Chlorine over 0.2...?!?

    New pool, opened about 5 months ago. I've been balancing the chems regularly, cleaning it, and keeping everything in tip top shape. However no matter what I do I can't seem to get my Free Chlorine over 0.2. At first I thought maybe my test kit was old (Taylor K-2006), but when I shock the...

    Adding more times to ProLogic 8 relay Aux, possible?

    In our first season with our new pool one annoying feature I've found with the ProLogic system our pool builder installed is the fact that the Aux circuits only have a single timer setting each day (will turn on/off only on cycle in a day). Why it works this way I have no idea... how much...

    Plumbing auto-fill at pad... where to tap in?

    Wrapping up our pool project (Austin, TX) and have decided to add in an auto-fill. Didn't want to pay the upgrade initially, but doing some research I've discovered the better option (to me) of plumbing it at the pad. Will likely make it manual at first, but I'm planning to eventually add in a...

    Crystalstones vs Quartzscape vs Plasterscape?

    We're nearing the end of our build and trying to lock down our plaster choice, looking for some insight on these products. Our PB kind of browbeat us to go with a pebble product initially, which is how we landed on Crystalstones. However, neither the wife or I really like the look of pebble...
