http://www.foxnews.com/us/2013/07/17/11-year-old-north-carolina-girl-electrocuted-while-swimming-in-pool/ Interesting how the girls in the water were fine until they tried to get out. It sure seems like the ladder should be at the same potential as the water - it's IN it.

Has anyone out there installed an in-ground light in an above-ground pool? It looks like the niches designed for I/G vinyl pools would probably work on an A/G pool. I'd really like something brighter than the typical A/G lights, and I'd like a more professional looking flush mount. I'm...

Hi all. I was doing some testing of my tap water tonight, and noticed some strange behavior. Here are my results (I was only testing CH - looking to get a new water softener): Test 1 - Cold Water (60 degrees) - 380 ppm Test 2 - Hot water (120 degrees) - 150 ppm Test 3 - Cold water heated in...

I have a SwimLine "Vinyl Liner Vacuum Head" that looks like this: I hate it. I am ready to throw it in the trash. :grrrr: I can't push down on it (from the outside of the pool with a telescoping pole) hard enough to get good bristle contact when moving forward. When moving backwards it flips...

I stopped by a friend's house to help him with his pool tonight. The pool is a vinyl IG with a deep end, 24" sand filter, and Hayward 400k heater. He claims it is about 30,000 gallons. The pool is crystal clear. He was concerned about the TA test going from green to light gold (instead of...

Does anyone know what the saturation level of cyanuric acid (CYA) is in water? Knowing that CYA takes a long time to dissolve, could one put a bag of it in a couple of gallons of water and have it completely dissolve in several weeks (or months)? Would it reach a point where no more would...

I'm doing some plumbing on my pool, and I'm curious if anyone can tell me if there will be a major difference in head loss between the following two configurations (ignore the periods). 1.)................Pump .....................|| .....................|| Main Drains === Tee === Valve ===...

Without dealing with the advantages and disadvantages of main drains on above ground pools, can anyone (Dennis, Matt, others) offer any advice on the installation of a pair of main drains in an above ground pool? I've just finished digging the deep end (approximately 22" deep) and the soil type...

I am in the process of digging out a deep end for a 27' round A/G. Over the last week we have had some torrential downpours (4" of rain just last night) and some of the side walls for the deep end are washed in and/or deeply trenched from all the water. The soil is extremely sandy, so once it...

Since the move to the dedicated server (or somewhere around that time), I can no longer see any smilies or avatars, from anyone, on any thread. When composing this message, the list of smilies to the left is just a bunch of dots. It's like none of the images are loading. This is happening on...

Does anyone know if there is a difference in the material used for an expandable liner compared to a standard liner? Does a non-expandable liner not stretch like an expandable would? To think about it another way, will a standard liner stretch some to conform to a bottom that has some shape to...

With approximately 300 new posts a day to this forum, how do you keep up with them? How do you moderators do it? To properly address the plethora of questions each day could constitute a part time job! Right now I'm logging in and using the "posts since last visit" feature, but I never know...

Hi, I am preparing to fill a new 18,000 gallon pool with well water. If I bypass the water softener, I can fill it in about 12 hours. The calcium level in the water is acceptable (for pools), but there is also iron and sulfer in it. The water feels very hard when not running through the...

Hi all. I will be installing a new liner on a 27' round above ground pool. I have not decided whether to use an expandable liner, or a standard beaded liner. I'm thinking about digging down the floor and using an expandable liner to give the pool a deep end. My question is, how are the...

Do any of you chemistry experts know if the solubility of cyanuric acid increases with temperature? I've looked at multiple MSDS documents from different manufacturers to no avail. I'm curious if taking granular cyanuric acid and letting it boil for awhile in a pot of water would dissolve it...

One of the major benefits listed for adding salt to a pool is that is makes the water feel soft. I have a water softener and understand the principles that it operates by. From what I've read, a typical water softener will not normally need to exchange more than about 300 mg/l of sodium ions...

I was doing a little digging on the web and I've noticed a discrepancy between the threshold given for tasting salt. Most of what I've read here and on the SWG manufacturer's sites list 4000 to 6000 ppm as being the point at which most people can taste salt. Earlier this year I added enough...

Since Ever know of anyone who doesn't like a SWCG pool? has been so lively (and I need to up my rank :wink: ), I have decided to throw out a survey. Hopefully those outside of this particular category will take time to respond as well.

For the sake of not getting off topic in Ever know of anyone who doesn't like a SWCG pool? I have started this topic. Does anyone know of an alternative to salt use in non-swg pools that will provide the same benefits as salt pools without the potential for damage to the surrounding surfaces...

I was looking at larger above ground pools recently and I was amazed that every one of them had one skimmer and one return coming though the same panel, not more than 2' from each other. I realize the logic for doing this has to do with the flexible hose lengths and having one stainless steel...

Hi all! I recently picked up a new 24" sand filter. I've noticed that filters 30" and larger tend to use a layer of pea gravel in the bottom of them before the sand is added to better distribute the hydraulic pressure on the sand when backwashing the filter. Does anyone know if this would be...
