Hi, I have iron deposits on my pool, especially the PVC fillings, etc. Last year I treated it with ascorbic acid at the end of the season when my chlorine was at zero. The staining has re-appeared. I plan to add ascorbic acid when the water temp gets low enough so that I do not have to worry...

Correction. Epoxy base coat, flakes, and polyurethane top coat with UV protection and shark bite. $4.50/sq ft. Any other alternatives that are solid and will cover up filled cracks but not look like paint?

My pool deck was coated with a clear acrylic sealer and is now flaking in some areas. Pressure washing has removed in some areas and in other areas adhesion is so good that it will not come off. I have had quotes for resurfacing and I like the option of grinding the surface, sealing, vinyl...

Ok. Dried everything and changed seals. It ran fine for 2 days and started the start/stop sequence again. Took cover off and no sign of water. Nothing seems to be hot. Any ideas?

No messages. Did take the cover off the controls and there was a lot of water. Changed the seals and letting it dry overnight. Will try again tomorrow.

I have a 2 year old Pentair Superflo VS pump that was working fine until this morning. It will turn a couple of revolutions and stop. After a few seconds it will repeat. Its doing this continuously. Checked the impeller and it seems to be turning freely. No error codes. Any ideas?

I think I found the problem. The pool store measured 30 and I added 2.5 lbs of Stabilizer. I then tested but saw no clouding of the test sample. The R-0013 was from a large bottle I bought a few years back. I had calibrated against a fresh reagent from a new kit and both tests agreed. I decided...

Nothing unusual with chlorine usage. Started out with liquid chlorine but have been on salt since mid April. Just got back from the Pool Store and they said that it was at 30. My target CYA is 70. Will add 4 lbs or so and see where I end up

Testing was done with a Taylor K-2006-Salt kit.

No any where that much.

Here are my test results taken today using my K-2006-Salt kit. FC 13.0 My generator that runs 12 hrs/day went for 80% to 40% with no significant reduction is FC levels. How come? CC 0 PH 7.6 Stays steady TA 65 Stays steady CH 40 CYA 0 It was 70 about 3 weeks ago after adding stabilizer...

My concrete pool deck needs help. Sealed it about 6 years ago with Behrs clear acrylic sealer. It did not look great to start with and has begun degrade. Bare spots, uneven wear,etc. Also got very slippery even though I added the sand additive when it was applied. HAve tried pressure washing it...

Not yet. Planning on adding 4 lbs stabilizer and 7 bags salt and then test.

Today's results. All from a brand new K200 kit. Let sample get to room temperature. Filter has been running for at least 16 hours. FC 4.5 PH 7.8 Alk 120 - Will let it drop to 70 CA 100 CYA less than 30. Filled up all the way to the top and could still see dot. Where did it all go? Salt 1,800

No auto fill. Have overflow but no indication of a leak. Level stays steady.

Meant to say TA

Dilution was my first thought but this is way more than what I have had in the past. Pump has been running 8 hrs at night all winter to prevent freezing and recently was on for a while while vacuuming. I am shooting for TA of 100 or so. Will check calcium tomorrow along with everything else and...

Pool was open all winter and lots of rain. Getting ready to start up SWG and wanted to balance water. Readings were FC 6 (had added some bleach) PH 7.4 TA could not read - out of reagent CYA 30 (was 70 in the fall) Salt 1600 (was 3,000 in the fall) Went to pool store to buy stabilizer and had...

I had a similar experience. I keep my pool open and there was record rain this winter. Both my CYA and salt dropped 50%. I was doubting my tests but it the results seem to confirm each other.

I installed a Circupool Si 40 about a month ago and have no regrets. Nice to have a steady of concentration of chlorine and not dealing with all the jugs of expensive chlorine. I chose the Si 40 since it was competitive in price, had a good warranty, and seemed to be a pretty generic unit that...

I have been struggling with how to hook up a planned SWCG to my system that has a VS pump with no external timer. The time solution does not seem fail safe since if the pump were to fault, the SWCG would still run. Your solution seems to be the best. Can you provide pictures of your final...

20k gallons. Will go with a 40k unit.

I have a 20k gal vinyl pool with a Pentair Superflo VS pump. Looking at Circupool RJ45-45 Plus, Hayward AQR15, or Pureline PL7707. Any strong recommendations? Any insight as to when there are the best end of season prices? I would like to avoid adding a timer (I use the one built into the pump)...

I seem to be having a similar problem and will start a slam. Would Mustard Algae cause high PH levels? My PH rises from 7.4 to 8.0 in 2 days.

Its only 5 months old!

It always did make that sound but it has gotten noticably louder over the past few weeks. I am running it more on slow since I am not swimming as much with the cooler weather.
