Hey guys, I recently had our nonfunctioning salt cell replaced and have switched over from chlorine to salt. I am confused about the CYA target. I thought it was a goal of 30-50 CYA for a chlorine pool, but I'm reading now it should be higher for a salt pool? Can someone explain this to me? I...

Hello all, my pool chemistry is out of whack and I would appreciate any advice. Our CYA is 185 ppm with Free Chlorine of 27ppm. Our PH is also very low based on using a test strip and from the Leslie's pool store test, which yielded a PH of 6.4. I tried to test PH with our Taylor kit but the...

Walmart is out, Lowes and Home Depot seem to be out, and even Amazon is out. I just can't force myself to buy from Leslie's for double the price...ugh. Any suggestions on good cyanuric acid sources or is it sold in places other than the pool section of Lowes/Home Depot, etc?

Have been a pool owner for a couple of years and just discovered the TFP method. I used to go to the pool store and get the water tested and add the chemicals they gave me. Starting last year, I noticed that I would be constantly brushing up what I thought was dirt on the floor of the pool...

Hi, SWG, floor cleaning system, intellichor pump, 27000 gallons inground, in the woods, sun morning, afternoon shade. Maryland. Running SWG at 60% for 10 hours a day. Water looking amazing. Ph was high, CYA low. PH 7.9 FC 5.0. TA 100 CH 300 CYA 0 80 °F Chlorine was a bit high for my tastes...

35,000 gallon in ground vinyl pool, SWG A few years back this forum helped me realize low CYA was my major problem (0-10 CYA in a Salt Water Pool). Once I got it up to 70 using the sock method I have a crystal clear pool that's very easy to maintain all season. My problem is the low CYA...

My husband and I bought our home last spring and it came with a pool that hadnt been opened in a year. The cover was ripped and the water was basically black. We removed the cover last summer because it was just shedding into the pool. We weren't living in the house yet so we couldn't devote...

Hello all. So my pool developed mustard algae, I think after the chlorine level decreased when I left town and with the heat and water evaporation, the water level went below the skimmer and warped some of the pipes, making the pump lose prime and stop working. The mustard algae, which I had...

Hi guys. I'm new to the forum and to pools. I just installed a 20x40 (maybe 35,000 gallons?) vinyl liner salt water pool in Long Island, NY. It's been filled for less than a month. My pump runs from 8am til 8pm with the SWG at 85%. I just got my K2006C test kit and have been reading as much...

Hello all....... as I usually do at the beginning of every season, I take my water sample to the pool store JUST TO REMIND myself of how much I’m saving, how happy I am to not have to go in there all the time, and to see if I’m getting numbers anywhere close to what the pool store computer gets...

Opened my pool yesterday morning and started testing. ph 7.2. CYA was 0, which I've not had before --usually there's at least some when I open in the spring. I added 5 lbs of dry stabilizer via skimmer sock. CYA should have at least been 20 , and my CYA test showed some cloudiness but was...

Hello Everyone, I opened my pool about a week ago and I'm dealing with a semi-cloudy pool (not bad, I can see main drain fine) and the smell of chloramines. I'm in the NE, I have loop lock cover and the pool water is usually disgusting when I open it - that's why I try to start early. I...

Greetings!! Recalling a 10" snowstorm on May 10th circa 1978 I'll roll the dice and say it anyway - thank God that Winter is gone and it's nearing the time to setup the pool. It's been a long, cold Winter here in the Northeast. Couple of quick questions. Have the Min / Max parameters for Pool...

All the CYA I ever bought looked the same, no matter where I bought it - pool store, Aldi or Bunnings. I never questioned that it could look any different, and always assumed that this is what is called "granular" CYA here on TFP (to differentiate it from "liquid" CYA). Even though I always...

Just bought a house with a pool. Pool appears to have been kept up very well and is only about 10 years old. In North Texas (Dallas) area. I knew nothing about pool keeping and have learned a bunch from online sources including this group. Very thankful for everybody here. One of the more...

Hi, I'd be curious to hear about everyone's experience with chlorination strategies to figure out what would work best for me. For many years, I've been using trichlor pucks along with calhypo for shock with mixed success. It's been pretty painful to deal with the high levels of CYA and the...

I found troublefreepool and the pool math app after I had already gone a month into maintaining our new 27' x 54" AGP using the chemicals purchased from the company that sold us the pool. Even just a month in, the CYA had climbed to above 60. I was still trying to figure out how everything for...

My CYA level (>90) appears to be interfering with my algae control. I understand that to reduce my CYA level, I have to pump down my pool and add fresh water. Can someone provide guidance on how much old water to remove and replace? My pool is 16 x 32 and has about 21,000 gallons. Thanks Bob

Hi friends, Just got a new liner and filled my 25,000 gallon pool I have a test kit and find that FC, TC, pH, are at the recommended level. But I have not added CYA. That level looks like 0 to me, as the black dot does not change. The Pool Math calculator seems to tell me to add 16 lbs. to my...

TFP Friends - I think the key question I have here is whether my black dot has disappeared (see picture below)... I have other sub-questions I would love to hear feedback on. If that dot has disappeared, then I'd say my CYA is around 40, which I believe is too low and might explain how much...

First, I want to say that we are first time pool owners of a 10k gallon, vinyl, filter cartridge using, chlorine eating, in ground pool, which came with our home purchase last fall. I've added what I know in the about me portion. If I didn't do something correctly just let me know. Based upon...

I have followed instruction from TFP in past two month and the result is amazing. Water is sparking clean with no need for shock for more than a month. I had to drain water once to lower CYA to around 60, but the problem was a left-over from previous use of dichlor and trichlor. I am...

I have an outdoor above ground pool. I have been using stabilized chlorine 3" tablets for several years now. This year the CYA level got too high. I had to drain 1/2 my pool. I switched to unstabilized chlorine tabs. My CYA levels are now at a proper level. I have been warned about the...

New to pools. Depending on the store, when I take my water in to get it tested I have gotten readings of 60 to 100 for CYA. I am using bleach, borax, baking soda, muratic acid and some calcium hardener as chemicals. Are their tests just wrong or why would it go up if I'm not using any tri/di...

It's first time I post a question here on TFP. Really love how informative the forum is. I need help on finding a bulk water delivery service in North Dallas area around Plano (75025) to refill my pool with about 13000 ga water. My backyard faucet can only supply 300 gallon per hour and it...

I had to drain a bunch of my pool because of CYA of ~110 or so. Since that time I have been judicious with my use of trichlor and have instead been using bleach to sanitize. For my 14500 gallon pool I’ve been adding close to a gallon of bleach per day and that seems like a lot. Could there be...

I seem to have an unusual situation with my CYA. At the beginning of this season I used tabs to get my CYA to 50, them switched to liquid chlorine. Few weeks later I checked my CYA and it had dropped to 30, added several more tabs, back to 40, few weeks later dropped again to about 30. Since...

Starting this year, I took over taking care of the pool myself from a pool service. I’ve done a lot of reading and research, and testing! Unfortunately, in the beginning, I was using Clorox shock and pucks, and test strips. Since then, I’ve run into this group, and have switched to purer...

Hello, I have a 17k gallon pool plaster cartridge filters and this year I seem to be having alot of issues with balancing the water: My current test results are : FC: 2.47 TC: 2.8 Ph:7.9 Alk: 77 CYA: 119 Calcium: 202 Iron/Copper : .01 Phosphates: 1691 Pool water is crystal clear with occasional...

Hello, I have a relatively new saltwater pool (11/1/2019) that I can't seem to get back into balance. As a result of allowing my CYA levels to drop to zero, my FC levels quickly followed (Florida sun). In an attempt to get my CYA/FC levels up rapidly, via stabilized chlorine tablets &...
