That seems likely. My son reports that it looks like concrete under where the liner goes.

We are replacing our vinyl liner for our inground pool, the new liner arrived, the installers drained our pool, started to install the new liner, and discovered they had been sent the wrong one. Now we have a large, empty hole in the ground where our pool is supposed to be and we won't have a...

Honestly, this site is the "go to" place for good pool info. I came across that, too. On the other hand, there would have to be an environmental trade-off. If my casual assumptions and quick math hold, the extra replacements requiring the pool to be emptied and refilled could increase water...

Re: Why so much hate on pool store's water test? In retrospect, major function of the Pool Store tests seems to have been to open up an opportunity to $ell me pool chemicals that I didn't need, and in fact, should have had no place in my pool.

I’ve noticed differing and contradictory information out there on factors that do or do not affect how long a vinyl pool liner will last, including: FC levels (Consensus here appears to be that as long as you’re not significantly exceeding SLAM levels, that chlorine won’t shorten your liner...

Just by way follow up, my CC measurements went back up, then eventually hit a real rising trend a couple of weeks after that last post. (I was what? At least three full weeks of slamming by then?) Then I finally found this other thread, starting here. Well I had been using this same vial for...

Each day I measured at dawn and dusk, and most, but not all days, I arranged for my wife to measure over lunch. My pre-SLAM CYA figure was after I had been raising the level with trichlor tablets, and I didn't know if I might have a false low reading for a week, like you get by adding...

Re: stuff on bottom: Yes, the stuff on the bottom disperses readily when brushed. Re: Probably algae: If it is algae, could it be mustard algae, given all the time it's taking to resolve something that seemed relatively minor? It's been in my mind, but there are definitely some differences in...

A few weeks ago, my pool started collecting greenish powder on the bottom. It did NOT climb up on the sides. It felt neither spongy nor slimy, I couldn't feel anything at all when I tried to rub it between my fingers. My pool is covered under a screen (don't know whether that's supposed to...

My pool is fully screened in, so it gets less debris from the environment. A few weeks ago, I decided to try running the pump only half an hour per day starting when I add chlorine. I've invested in a nice skimming net, and spend a few minutes daily skimming, and vacuum any debris from the...

Looks like you did it right: I wish I had done what you did. I started out last summer, and it was a nightmare before I found the right information (this site was my best source). It also cost me hundreds of dollars (fortunately not thousands) following bad advice from local pool stores in an...

Thanks for the great info!

The picture you see shows my filter housing, which contains a cartridge filter. Last fall, a "pool school" guy came out to give some basic information. If I recall correctly, one of the things he said was not to use the drain plug shown in the picture to drain water from the pool (the one...
