My neighbor asked me to help him because his pump was.losing prime overnight. Replaced lid o-ring, replaced multiport, looked for suction side leaks. Found nothing. But still losing prime an hour or two after shutting off pump. Then, randomly, my pool started doing the same thing. Replaced...

My TA was 80 but I wanted to get it up to 100 (for some reason). I added Baking Soda but it is now 150. My question is if a TA of 150 needs to be addressed. I know its not in the ideal and recommended range, but should I leave it or address it? Will it fix itself? Thanks

Closed pool but after plugging the returns, still had some bubbles coming through. Tightening the plug didnt help. Then, went to pump basket and found it full of water even though pipes were running dry air (main drain was open, could water have come through there?) Removed plugs from pump...

Mustard Algae. Passed OCLT, CC = 0, Crystal clear water. But yellow algae seen in clumps on floor. Listened to pool store and added 2 lb of Sodium Bromate followed by 3 bags of shock. Although they "guaranteed" that this would clear the pool within 24 hours, it did not. Added a total of 18...

It is January and freezing but I am thinking about the pool. I have a painters pole with the standards screw top attachment where a painters wand would be mounted. Is there any way to convert this for use with pool skimmers and brush? There has got to be a product out there that makes the...

The previous owner's old flimsy winter cover for the pool heater is all ripped and torn. I am ready to buy a regular bbq grill cover for the heater, as suggested by the pool store when I didnt want to shell out the $60+ for a "pool heater cover." But I read that some people recommend not...

First year closing pool myself. Blew out lines with shop vac attached to a skimmer through system with all drain plugs still in the filter, pump basket and heater. 1. After capping the return lines, tried to blow air into main drain with shop vac but no bubbles but closed off valve anyway. I...

FC 24 CC 0.5 TA 90 pH 7.5 CYA 40 Pool was sparkling throughout July and into August. Went on vacation and left pucks in floater. Came back and tested FC 2 and CYA 40. Next day noticed clumps of yellowish "dust" along bottom. Ran polaris thinking it was sand, but just kicked up and settled...

Pool passed OCLT over a month ago. Been hosting heavy swimmer load. Usually sparkles in direct sunlight but as soon as it is in shadow or night, it gets cloudy. And a few days ago there was a green tinge/algae outbreak that called for a second SLAM, which took 2 days until passed another OCLT...

This heater did not fire up last year and was told by one pool company that needs to be replaced but a second one got it working by putting in a new pressure switch. This year it was working, then we went away for a week and now it stopped working. I cleaned it out a little and it fired up this...

I opened to a swamp 24 days ago and it is now sparkling clear. That is the good news. The TFP method alone did not get the whole job done - that was my experience. This is our second year with the pool and loving it. Being in a wooded area and with a mesh cover, we open to swamp. Last year, the...

Just got back from Leslie's pool supply and guess what?.. they are selling chemicals that lower CYA. The package claims that one $50 bag can bring CYA down from 100 to as low as 30. If this is true, it is a game changer. Would allow us to use pucks and kust throw this stuff in when CYA gets too...

FC 18 CC 0.5 pH 7.4 TA 40-60? CH 20!! CYA 40-45 Day 24 of SLAM and pool still a kind of cloudy-blue. Vinyl pool - should I raise calcium? In alkalinity test, the color changed immediately on drop 4 but went back right away. Drop 6, it changed and stayed. So I assume the TA is 60, not 40...

I saw this question asked in 2014 but nobody answered. The pressure rises and looks like time for a backwash but then when the pump is turned off and back on, it drops back to the starting pressure and doesn't rise again for hours. Is this normal? And in this case should I backwash or let it...

I am sure that this has been addressed before but a quick search didnt find the answer and I am running out so thought I would ask again. When testing CYA I stand in full sun with my back to the sun. But is the tube supposed to be in the sunlight or in the shadow? I did both and almost a 10...

Here I am again. New sand filter installed last season but Day 10 of SLAM and just not filtering out the water (fast enough) for me. Somebody suggested replacing the sand with glass, claiming that it is faster and gets finer particles than even DE. Is anyone familiar with this? Here is a link...

I know this has been addressed but not my specific issue, so thought I would ask the forum and maybe somebody can help. Have been adding DE to sand filter for about 24 hours, backwashing as needed although the pump did run for 5-6 hours at high (+8) PSI before one of the backwashes. Yesterday...

Opened the pool to swamp and these readings FC 0 pH 8.2+ TA 60 CYA 0 Decided to add CYA and MA to lower pH to 7.2 Based on PoolMath added Stabilizer in sock and MA. But readings came out FC 0 pH 6.8- TA 40 CYA 60-70 Added Washing Soda to increase pH according to PoolMath and retested this...

Opened pool to swamp. FC: 0-1 CC: 0 pH: 8.2+ TA: 60 CYA: 0 Do I add Muriatic Acid to drop pH or first adjust TA up to 110 by adding baking soda? Or should I do both? Also, need to add CYA and chlorine. Can I do all at the same time or there a recommended order? Thanks

This was my first year with the pool and used TFP method all summer. With two weeks left till closing, decided that it was too much time and money to continue daily testing and bleach additions, so threw some pucks in a floater. I dont mind CYA rising cause only a couple more weeks. The pool...

Hi all, So we had a full algae bloom and SLAMed the pool for a week. Water was totally clear and FC read 17, CC 0, passed overnight test. Let it drift down for 30 hours and now the reading is FC 2 CC 1.5-2 TA 80 pH 7.5 CYA 30 What does the CC reading indicate...am I going to have to start a...

I have been using pool chlorine (10% cal-hypo) and couldn't find anymore in the local Walmart so switched to generic laundry bleach (8.25% cal-hypo). When I poured it in the pool, it created thick white bubbles all the way to the floor and a few minutes later there were clusters of white...

Pool water is clear and FC drops 3-4 ppm every 2 days. Lately we had a lot of rain and the jet was pointed up so I think the water was aerated. Either way, the pH has been fluctuating and testing is producing a range of results. TA was 120 for the longest time and is now shoing 90-100...

I put in a new sand filter about a month ago and whenever we run the filter, notice sand (looks like beach sand) and some debris on bottom of pool, particularly around the returns. The Polaris picks it up and it remains clean until the next time we run the filter and the sand returns to the...

I was SLAMing out green water so keeping high chlorine levels. CYA was below 10 so I added stabilizer through the skimmer two nights ago. Tested next morning and found FC 23 CC 0 pH 7.2 TA 120 CH 150 CYA 30 water was crystal clear until big swim party today and water turned a bit cloudy so...

Is 18 PSI starting pressure too high for sand filter?

My pool has been green since opening, although the water did clear alot and the green is lighter, but still there. Here are the numbers according to TF-100, is there anything here that accounts for the green? FC 21 CC 0 CH 150 TA 120 PH 7.6 (after 30 seconds color darkened to 8.2,which reading...

Hi, I am new to pools and eager to learn the BB method. I had an old and broken DE filter and at the suggestion of the pool company, replaced it with sand. I now fear that I made a mistake! Is there really a noticeable difference between the clarity of DE and sand filters? There is DE in my...
