Hello everyone. I have a couple of Aqua/Lamp SK pool lamps in my pool and both bulbs appear to have burned out. It looks like those bulbs are basically the same as the 4" headlamps on my garden tractor. From the lamp housing, I see: 12 VAC, 15 A, 60 Watts max, Type PAR 36. The bulb has A51...

I think that very little suntan lotion has been washing off from the swimmers. My wife and I usually just go for a swim after getting home from work and we've only had 2 pool parties this summer and I don't think anyone used lotion on those days. I just use an old j-cloth to wipe the skimmer...

I had a look at Pool School and read through "The ABC's of Pool Water Chemistry". I was aware that using the trichlor pucks causes a build-up of CYA, which has an affect on free chlorine. As I have to drain down the pool for winterizing, every spring I have to add granular stabilizer through...

That makes a lot more sense than the residual effect of the HTH trichlor tablets I used a few years ago. Would there be any chance that stearates could could contributing to the black scum problem I've also got posted here? For the time-being, I'm going to continue using the ClearWater...

The gummy residue is in my chlorinator (see photos in my first post). I could manually dose with liquid chlorine but I would much rather have a feeder do it. If I have to do it every day manually, I think there would be many missed dosings. I have enough trouble remembering to do the weekly...

I had my doubts about the accuracy of the store's test results as they appear to be using whatever test equipment provided by their chemical supplier (this year's equipment seems to be problematic and seems to be down as often as it's up). As long as they used the same test strips and scanner...

Switching to liquid implies that all pucks are susceptible to this problem. My impression from talking to the pool store manager was the pucks they supply are so pure that none of their other customers have this problem. I get the water tested weekly and have test results for pretty much every...

This year, I noticed that there was a black, oily scum in my skimmer. Is this likely from atmospheric pollution or is it from something in my pool's chemistry?

I'm using a Waterway ClearWater Chlorinator (off-line) with chlorine pucks I've been getting from my local pool store in 7 kg pails. I believe they source their chemicals from Sani Marc Inc. The problem I've been having lately is a gummy residue inside of my chlorinator. I've tried dissolving...

Yes, I do mean plumbing and not automotive antifreeze. The label does mention pools and I've got both PVC Sch40 pipe and Tigerflex hose in my system. http://www.recochem.com/en/products/out ... tifreeze1/

I bought some antifreeze to close my pool this fall. I was looking for propylene glycol and most of the plumbing antifreeze seems to contain ethanol instead. I saw that the gallon-size jug of Prestone contained propylene glycol and decided to go with the a 2 x 2 gallon package that was on...

Well, the piping guy sent out by the contractor seemed to be highly regarded by the contractor. He was a nice enough guy (a little rough around the edges) but I think his main qualification is that he took the job way back when. As with a lot of places, "you touch it - you own it". I know...

I was just planning to leave the pump in place and rotate the filter 90° so that I could use a single 2" long-radius elbow to connect the pump and filter. I also would like to use a 2" long-radius elbow to connect the filter to the heater and bypass piping behind the filter. The heat...

Thanks! The water looks a bit green because we used filtered (5 Micron) pond water to fill it. Even with our pond pump running steady, it was still taking a long time to fill so we trucked in some city water. The big hose you see in the photo is from the truck. The garden hose (beside the...

As you can see in the attached photos below, the piping installed by the pool contractor is a bit ugly and I would like to correct a few problems by redoing the piping. The main problem is that the pool heater (shell & tube heat exchanger visible on wall below the siding) is poorly accessible...

Hello Everyone, I'm in the Fort Erie, Ontario area and we installed a 19x35 Grecian-style in-ground pool this summer. Construction started in June and we were able to start swimming in late July. Luckily, we had a warm summer and managed to have water temperatures in the 75-80°F range until...
