I have sand slowly accumulating on the ground near the waste pipe for the last year or so. Could this be caused by a cracked or broken lateral?

Getting ready to sell our house. Had pressure washing done including around the pool. The concrete was dark in areas. It is a concern if some of this gets into the pool? Should I SLAM as a preventative?

It's been 11 years since I've balanced new pool water but we just installed a new pool liner and refilled the pool. Please refresh my memory on what order I should add the products in order to balance properly.

In the last few days, we have encountered MANY bees around our pool. They seem to like the overflow drain cover and the pool floats. This is the first time in 11 years of pool ownership that we have had this problem. Any ideas on how to proceed?

I started a SLAM on Sunday and the sun is really doing a number on my FC levels during the day. Yesterday I was losing up to 9ppm in just 3-4 hours but only 2ppm overnite. My CYA was 60 when I started; is it okay to add CYA to help keep the FC from dropping so much during the day? I'm willing to...

I just wanted to confirm that the following brands are okay to use as liquid chlorine (the ingredients seem to match with regular bleach except 10% sodium hypochlorite). I wasn't sure about the "other ingredients" which is listed on regular bleach and also these products. Both are currently in...

Spent 6 weeks performing a SLAM in Feb/Mar. Since then pool #s have been spot on and the water crystal clear. Two days ago I noticed algae on two of the ladder steps and also on the walls of that corner of the pool. I was perplexed but I think I know the reason and am looking for confirmation...

I received a flyer in the mail about the "Drinkable Pool Water System"...an AOP system that uses titanium-generated hydroxl radicals. Does anybody have information on this system? Does it work? Is it cost-effective?

I recently performed a SLAM...started on Feb 2 and ended by passing the OCLT on Mar 15....that's 6 weeks! It took a lot of POP and there were many times I was down and frustrated but it worked. It's a good thing it ended on Mar 15 because it was that weekend that bleach became non-existent at...

My chlorinator died in November and, with a very warm winter so far, my pool had become a very dark green. My time has been limited since then but I started to SLAM 8 days ago. As the SLAM progressed and the dark green became a lighter green then grayish green as one would expect. It continues...

My chlorinator died last fall and I haven't had the time to SLAM. So now my pool is a very dark shade of green. I'm in a position now to SLAM which I'm comfortable with. The clear bubble on my filter has no visible algae which it usually does when I get an algae bloom. Do I have a problem that...

My Hayward T-Cell-15 just went out after 10 years. I'm looking online for a replacement but it is confusing because I see such a huge range in prices. Obviously, I don't want to spend any more $$ than I have to but I do want a reliable replacement. Are the Hayward-compatible knock-offs any good...

Just replaced my pump on Monday (laboring on Labor Day) and it's appears to be running fine. Now my pool level has dropped 1-2 inches and the pressure gage on the sand filter is reading zero. I cannot find any leaks (i.e. no wet areas) anywhere around the exposed plumbing, filter, pump etc. My...

My pump died and I'm hoping it's just the capacitor (the impellor moves freely). I bought a capacitor for less than $7. All the numbers on the new one match the old one except the old one says 124-148uf and the new one says 124-156uf. Will the new one work?

Here's the background I am wanting to perform the AA process to remove my pool stains. I was allowing the FC to drop and when it reached the minimum FC for my CYA level I added polyquat 60 (the higher initial dose on the instructions). I then waited for the FC to drop to zero. Then I had to...

My first time using polyquat 60 coincided with my first ammonia event shortly thereafter. Can there be a connection? I'm planning to redo the AA method soon (my first attempt in May was sabotaged for various reasons) but I don't want a repeat of the ammonia. Thank you

I have my 2nd bout of Chlorinator Off-No cell power in the last month. After the first one I had the K1 relay replaced at a local computer repair shop. That worked for a week and a half, then it happened again. Do the K1 solder burns generally occur due to lightning or a surge in the local...

Has anyone else noticed/posted on recent changes I've noticed to bleach concentrations? The "concentrated" bleach at my local Walmart used to be 8.25% but now it's 6%. Same thing at my Publix. I haven't check Kroger or others. None of these reduced concentrations came with a reduced price. :(...

About 4 weeks ago I got the infamous "Check System - No Power Cell 2" which means a burned out solder joint on the circuit board (which I confirmed). Since the FC was already low because of that I decided to go ahead and add polyquat 60, allow the FC to go to zero and perform the Ascorbic Acid...

I'm using the ascorbic acid treatment for pool stains as shown in TFP. I'm not sure the sequestrant I'm supposed to add after the AA is a proper one. I used Metal Magic last year but that wasn't available to me so I was given something called Metal Free from Natural Chemistry. The label says...

I have the following messages showing on my AquaLogic Chlorinator Off - No cell power Check System - No Cell Power 2 The cell (Turbo Cell T-CELL-15) is over 8 years old so I'm guessing that the cell needs to be replaced especially considering that the FC level has been dropping (now at 0*)...

I live near Atlanta and it's unseasonably cold here (forecast low 20F). My pump was circulating earlier today but now it's not. Pool surface is now icing over and I'm very concerned that my pipes will get damaged. Any advice? - - - Updated - - - One other thing. The pump motor is running but...

Just finished with stain removal process (it worked great...so far). I'm ready to begin rebalancing the pool starting with pH and TA. The ascorbic acid brought the pH down to 6.9 and the TA to 60. The pH section of Pool Math says to add 33oz by weight/28oz by volume of washing soda. The TA...

So yesterday I backwashed my filter then did the rinse. I turned the pump off after the rinse. I woke up this morning to find that water level had dropped 8 inches! It was then that I noticed that I had neglected to return the filter to the regular filter setting. Is it normal for the pool to...

Wondering if I need to SLAM. Water getting somewhat cloudy (water temperature 89F). All metrics have been within range. Here are the current readings: FC 4.5 CC 0 TA 65 pH 7.7

I'm in the SLAM process and noticing that the jets are ejecting very tiny air bubbles...not continuously but a shot about every 5-10 seconds. Should I be concerned?

Over the last few years the vinyl liner has become stained...from bright blue to a darker, dirty look with small patches of the bright blue especially near the bottom drains. Is there anything I can do to remove these stains?

My pump has stopped running. When it tries to start, all I hear is a hum for about 10 sec then nothing. I read in another thread that it could be the capacitor so I pulled it out but it tested ok. I hate to replace a motor if I don't need to. Any thoughts?

Just finished my first SLAM 5 days ago. Did some testing and here are the results (post-SLAM pH was measured after FC dropped below 10ppm). I have a SWG. Pre-SLAM...CYA 80 pH 7.2 TA ? (added MA to lower pH from 7.8 to 7.2 to prepare for SLAM) After.........CYA 50 pH 7.2 TA 90...

My pool was so pea soup green that I couldn't see most of my hand when it was submerged to my wrist and I couldn't see the returns at all. After slamming it, it has NEVER looked so clear!
