I have old 12VAC niche fixtures where I'd like to screw in some 12V LED bulbs. Here's the trouble: I used a multimeter to measure voltage at screw in socket. It's 13VAC. But when I screw in the bulb I get no light. I shined up the socket with some fine sandpaper so I don't think corrosion is the...

We have a dead Pentair Warrior SE. A big disappointment that worked fairly well for just over 2 years, the warranty period, then died the usual way. Should I buy another Maytronics robot or will it just die in another couple years? The guys at Leslie's where we went to look at them say...

Our Pentair Warrior SE, purchased from Marina in May 2020, died with what appears to be the usual problem: The motor self test fails after starting up and moving a few feet. I followed some suggestions from this forum and checked the impeller and impeller motor shaft, they are clean. I contacted...

I've seen a lot of recommendations here on the Dolphin S200/Pentair Warrior Se/Dolphin Active 20 that sells for around $700. Not so many for the Aquabots. Is there a disadvantage to Aquabot? Also, I've seen where some people found the Dolphin Active 20 at pool stores for $629 - rebate. Anybody...

Hi, all, I'm thinking about painting the bottom of our hybrid concrete/fiberglass pool this spring. It's currently painted white and hasn't been painted in about 10 years. It doesn't look really terrible yet. There are some worn areas where grey concrete is beginning to be visible plus a few...

Last summer I had 50 or so PPM of CYA. Drained about 1/4 of the water out for winter. Now I have 0. Same thing happened last two springs. Where does it go? Do the cold and freezing degrade it somehow?

Looks like approx 800 KWH/month to run our pool pump! This month's electric bill happened to start just the time we opened up the pool. Makes sense, as it's a 1.5 HP pump running for about 16 hr/day. So, is it time to think about a variable speed pump? Here's the dope on our setup: 25000 gal...

Came back from an 8 day vacay to find our pool looking like the proverbial Jolly Rancher. I had put 4 3" HTH pucks in the only-used-when-away inline chlorinator, so not sure why things got so far out of hand. Pool had been good until we left. Anyhoo, I pool calculatored 15ppm chlorine as shock...

We've got a Jacuzzi Sherlock 160 cartridge filter. Filter body manufacture date is 2005, and it's got an aftermarket cartridge in it now, so it's maybe around 4 years old at a best guess. Cleaned cartridge when closing; it runs about 20PSI with filter gauge about 5' below pool water line...

Thinking about getting a solar cover. Pool is a free-form curving L shape, so it would be kinda difficult & expensive to get one piece to cover the whole thing. I'm thinking about just covering the deep end with about a 15'x30' cover trimmed to fit as in diagram below...

Our plumbing currently goes from cartridge filter about 15' horizontal to the gas heater then 15' back to a chlorinator (left empty most of the time) and out to the pool. All this is in our basement; lines then go up and through the sill plate out to manifolds and then to the pool. There's no...

We're looking to attack our leaky fiberglass walled IG this spring or summer. Have sort of eliminated the obvious already (pump/filter/heater, did some food color testing) without finding out much, so I guess it's time to find a pro. At least we've got plenty of nice rain water in the pool! -...

I think I read in the big pool closing thread that if lights are near lowered water line, I should remove them from niches and set on deck. My lights are cone-shaped reflectors with glass domes that sit in cone-shaped niches. The lights themselves come out with one screw at the top of the bezel...

After calling around and finding out that closing services are around $350-400, I think we're going to try doing it ourselves. I think Speedo is correct in pointing out that there's plenty of advice here, even some differing opinions which shows posters have really thought about what they've...

We're new to the pool scene, so looking for a pool service to close at least this first year. Located near Gurnee, IL. Any recommendations? Horror stories?

We've got a Sundance Marin XXI hot tub at our new house. It's about 10 years old. Previous homeowners used it up until they moved out, and it's still turned on. Appears to be in good shape, I suppose because of not being outdoors. It's indoors, consuming most of the space in a sunroom that we'd...

Looks like my 25K gal pool has only 110 CH - probably because the water we're topping it up with is more like 80 CH. Pool Calculator says to add 32# CaCl to bring it up to 250 CH. I plan to add about 8# at a crack and test to make sure I've got it right. Supposedly AceHardware.com sells a 50#...

We may have found our 1"/day leak, maybe. According to my figuring that's about 2 cups/minute. Going around a lot of the pool with food coloring and a syringe showed up one spot that seemed pretty suspicious. It's around our large skimmer frame where there's a couple smashed in parts on both...

OK, so I've got an extreme knowledge deficit. We just moved in a couple weeks ago, never had a pool before, never really even looked too hard at other people's pools. These pictures: [attachment=2:1u9g1otc]DSC03130.JPG[/attachment:1u9g1otc]...

Prev owner left me a Taylor K-2005 test kit with a fair amount of juices left, but unknown age. This is like the good kit (K-2006) without a FAS-DPD setup. Question is, should I just buy a FAS-DPD test or should I buy a whole new kit? Do reagents go bad in a couple years time? If just FAS-DPD...

Looks like my CH may be low (need to double-check). If so, can I use cal-hypo for my chlorine needs? My local wally has HTH granules for $55/ 16lb bucket - ok deal? good product with no CYA? How do I use it? Thanx as always.

Wondered how much water we should have to add every day in this heat - seems like it's down about 1" per day. Previous owners left us an automatic filler that works on a garden hose. We didn't use it for a couple of days and water was down far enough that skimmers were sucking in a bit of air...

I'm sure you guys have heard this one before... We just bought a house with a pool. Got the basic rundown from the seller: It's 25000 gallon, he showed me the pump, cartridge filter, place to put the chlorine pucks, valves, strainers, heater, etc. Then he handed me his Taylor K2005 test kit and...
