Does anyone have any good leads on where in the DFW area to find liquid chlorine during the coming fall and winter? Walmart has pulled all of its supplies, and Lowes and HomeDepot are asking $2.30 more per gallon than Walmart, even in volume.

This is not a question, it is to provide a heads-up to others who have older Pentair skimmer boxes in their pools and wish to replace a broken weir with an original equipment Pentair weir. I have been using universal weirs that work fairly well but often come loose due to the heavy sloshing of...

I have a 30+ year-old inground pool that had friction-secured weir doors installed when I moved in. One just failed. When looking at the underside of the skimmer cover, it has markings of "Swimquip U3" which seem to indicate a Pentair weir skimmer assembly. The Pentair weir door has a base plate...

The pool app recommends an ideal range for calcium hardness between 350 and 550. This is far higher than any other recommended numbers I find online, which are more in the 200-300 range. What is happening here?

Looks like we are back in the soup for chlorine this year. Aside from the fact that it has gone up over 50%, it's hard to find. Home Depot, who has one of the best prices, was sold out at Park and the ND Toll Road. Lowes has the most expensive in town, but I found some at WalMart (between...

Of all the chemical tests, I find the one for testing cyanuric acid the most problematic and unreliable. So, when does one decide the “dot is no longer visible?” Totally invisible and undetectable? Or just barely visible? This makes more than 10 points difference in the reading.

I happened to notice yesterday that my pool sweep was no longer moving . When I went to the booster pump it sounded a little different but it appeared to be running. When I fished the Polaris out of the water, the booster was not pumping. Any ideas what could cause this?? It's as if the pump was...

So, today I went down to buy several cartons of HD's 10% liquid chlorine normally packaged 3 to a carton. Today, all they had was 2 to a carton, and the net price per gallon went up as a result. Not only that, the date code changed. The date code on the package I bought was: 2014908 Now, I'm...

I have seen this referred to as "replacing the mastic", but the seal between my coping and the deck on my pool has developed a sizable crack. I assume this means replacement. The last time I had this done it cost me over $500. It looks like it could be a DIY job, though. Are there any...

I have an older plaster pool (in need of replastering) that I seem to be pouring acid into to get the pH down to 7.5 and keep it there. The alkalinity runs about 90, the pool is clear and I keep the chlorine balanced with 10% bleach. I know that water features can cause CO2 to be blown off...

Something weird is going on. Getting ready for the season, I just adjusted my calcium hardness (260) and added sodium bicarbonate to up the alkalinity. Rather strangely, it didn’t go up much (70). But, the strangest of all is suddenly I get ZERO chlorine indication! I know there is chlorine in...

I have an old Hayward sight glass with the 4 screws holding it together, and the glass (plastic) is so discolored I have a hard time telling when the water is running clear during a backwash. Two questions: a) It looks like to replace it I have to cut the PVC and replumb that part of the system...

Today I had to have a service call after tearing down my system for a routine cleaning and being unable to figure out why I was blowing DE back into the pool when I recoated the grids. After some close inspection with the pool guy we finally saw that ALL but one of my grids and totally blown out...

This is a new thread for an old topic. I live in Far North Dallas and had mixed results last year at WalMart, Lowe's, Home Depot, and Leslie's chasing down liquid bleach that had a reasonable shelf life and that was concentrated. I just bought two cases at CostCo this week and noticed they have...

Anybody have any experience with a solar-powered copper algaecide device that seems to work by electrolysis? I have read the downsides of using a copper-based algaecide but this device seems to put the copper ions right into the water without a chemical carrier compound.

Can anyone help me with this question. My Polaris 280 is going in circles. Even though I had it reworked about 3 years ago, it looks like it is time to install a tuneup kit. Going on line, there seem to be 3 kinds of kits ... a rebuild kit for around $300, an A49 tune up kit for around $150, and...

I have a great collection of almost new tee shirts with white spots all over them from splashes during the pouring of Clorox into my pool. I found a solution. From an auto supply store (or Amazon) buy a spill-saver transmission fluid/oil spigot that screws (tightly) onto the mouth of the Clorox...

I just used 4# of calcium hypochlorite to shock my pool, as I have developed mustard algae thanks to the rain floods in Texas. I should be reading about 25 ppm of chlorine, but my Taylor test kit shows almost no chlorine! It dropped my pH from 7.8 to 7.2. Why don’t I register chlorine with the...

When I cleaned my DE filter recently and reassembled it, I noticed a drip-drip leak from the drain plug at the bottom. The filter tank has a plastic cap with a small O-ring in it. I tightened it all I dare with water pump pliers, but it still drips. I just recharged the system with DE after...

Here are my readings via Taylor test kit: pH - 7.6 FC - 5.5-7 (depending on time of day) CYA - 40 TA - 60 CH - 300 BO - 30 Temp - 85 deg F No severe problems in pool (water is clear) but I have constantly creeping pH (up) and am adding muriatic acid frequently. I'm thinking of increasing the...

I have a Hayward Northstar single-speed pump and am getting ready to install a new Liquidator. Does anyone happen to know the thread size on the pump drain plug? The manual exploded view does not give the size. I need to buy a replacement piece with a barb to install the Liquidator output port.

It is recommended to port the output of the Liquidator into the pump drain plug by replacing it with a barb fitting. Anyone have any advice about the details of this operation? Looks like I will lose all of the water in my filter and heater with this operation.

What do I do with the Liquidator in winter when we get a Blue Norther in Texas that knocks the temps down into the teens?

I have a Liquidator on order but have several questions: - My only site for the Liquidator gets full sun about 8 hours/day. I have read advice to spray paint the container to protect from UV. Is that good enough or should one build some type of enclosure for it? If enclosure, anyone have an...

I have successfully moved from the pucks to liquid chlorine and finally have CYA under control (running about 55 right now) after being fed up with constant water changes. Under the relentless Texas sun I am consuming about 2 quarts + of 8.25% bleach a day, and I target my chlorine level every...

I seem to be using a lot of chlorine. The pool has been shocked, stabilized, and my readings are: CYA - 50 pH - 7.6 CA - 270 Tot AL - 70 pool volume - 18,500 gal (in ground plaster) Taylor K-2006 test kit Every evening I run the chlorine to 5 ppm. By the next afternoon I am down to 2.5 ppm. I...

Test was re-run and the aberrant reading was not observed. The earlier reading must have been due to a contaminated vial. ??? --------------------------------------------------------------------------- I just bought a Taylor K-2006 test kit. I got a shock this morning when I tested my pH. I got...

I have a 25,000 gal in ground plaster pool, CYA = 45-50, CA = 270. Totl AL = 70 pH = 7.5. I went through a shock and it finally stabilized at 22.5 ppm overnight. Then, the next day the FC plummeted to 12 during the day. Today it fell to 3 even after adding 2 quarts of bleach (8.25%). This seems...

I inherited a pool maintained by a pool service. Last December I had to dump half the water to get CYA down. Again, this month I had to dump about 2/3 of the water to get rid of CYA that apparently was in the pool walls and pipes. I have had it with stabilized dichlor and trichor, have removed...

In doing pool maintenance this week I noticed I have a cracked weir. Most of the sites on the Internet talk about spring-loaded pins that retain the weir in the housing. My weir is an old one, possibly 25 years old, and it looks to me like the only way to get the weir out is with a hacksaw...
