I opened my pool today and CYA is at 20 vs 50 when I closed it for the fall. We had some heavy rain this winter so since I drained a few times I thought it would be lower, but not by this much. I also thought that CYA could ONLY be reduced by draining, but now I read the following on TFP...

I have the speedstir and love it...except, it is not very water resistant. I have had to clean out the corroded contacts or even twice resolder the connections to keep it going. Any good alternatives out there?

going away for a week so going to use pucks and floaters. I have used them in the past and they do not seem to keep up very well with the FC demand so I use two of them, even then it is kind of marginal. So I wondered if there is a formula or suggestions for how many floaters are needed for my...

I only use liquid chlorine and my PH usually goes up very slowly. I usually have to adjust with Muriatic acid once a month or so. Lately it is rising very rapidly with having to add some muriatic acid weekly. I have added some water, not much, an no other chemicals, any ideas? ...or is it...

I use Liquid Chlorine 100% of the time...except on vacation. The floaters with tabs are OK, but I have had mixed results. What is the opinion about tabs in the skimmer if I set the pump timer to run 24/7 while gone?

I daily use the FC powder test (R0870/871) test in 10ml water. Today I had two widely different treading, although also from two different places in the pool. One had a heaping spoonful and one use a REALY heaping spoonful (which gave the higher reading), so can you use too much powder in the...

I typically only use LC for my pool, but I am doing some testing using chlorinating tabs for future vacation times. I have a 22K gal pool with two floating chlorinators and the 3 inch tables added are broken up for quicker dissolving, even so I am only getting 2.5 ppm so having to add LQ each...

I always use liquid chlorine (per TFP) except when on vacation. Then I use the floating dispenser with 3" tablets (and closely monitor my CYA). However, the dispensers seem too slow. I even use two floaters for a 26K gallon pool and they hardly keep up with demand. Any suggestion for faster...

I follow all of the guidelines here and have had no issues in 1.5 years. My PH rose (which of course it does via adding liquid chlorine), but after adding significant amounts Muriatic acid (couple of pints) it is staying high via the drop test. Very odd as adding a small amount of muriatic...

OK, I have just had my first trouble free year with TFP!!! Now winter is approaching, wonder about FC levels: Does it need to change now that it is colder, i.e. no algae growing in the cold, can it be lower? Still jug dump chlorine (no SWG) or add pucks? If pucks, how much is needed in the...

I have learned a lot about pool chemistry this year. First year no Algae at all! Before TFP I was told that even in winter you need to run the pool pump 8 hrs or so even in the winter. I reduce the RMP to save money, but in one of my posts this summer regarding pool chemistry I was told that...

I am in Northern CA, with tons of fires around us and lots of smoke. My PH had been holding steady but suddenly jumped higher. Can this be from the smoke and some ash from the fires?

My CYA is a bit lower than I originally thought (30 vs 40), so to raise it I was going to smash some tabs (pretty easy to do as they come in plastic wrap) and throw the powder into the skimmer. Any thoughts? I know, "not the skimmer!" but will be running the pump and will dissipate quickly...I...

If I typically lose 4ppm per day of FC with my recommended range of 5-7, and before I go on a 3 day vacation Take it to 16, will I still lose only 4ppm per day so on return I would still have 4ppm, or does it deplete faster at higher levels?

My PH levels measurements vary widely as per the time of day. EG. in the morning when the pool filter has not run for 12+ hours I get almost and 8.0, but in the evening, while pump has run all day and is still running, I get around 7.5. I tend to believe the evening one as when I put in MA is...

In the heat of summer now I am losing FC about 4ppm/day. my CYA is about 40, so as per the TFP suggestions should I be raising it to 60? seems high "It is very common for a manually dosed pool to lose 2-4ppm Chlorine daily however some users may experience a larger drop, especially in areas...

This is the first year I have been following TFP religiously, and the best year I ever had! I only use LQ (jug dumper), but on vacation for a few days I use pucks in floaters. However, in this hot season I need the pucks to dissolve quicker despite heaving two floaters. Other recommendations?

I have been at this house for 33 years with a pool, and while I maintained Chlorine levels (mostly), I never really paid much attention to PH levels until this year where I am religiously following TFP. In those years my pool tile have become severely caked with calcium (PH too high I think). I...

FC=6, PH=7.6, CYA=40, CC=0 I have been trying to keep my pool FC at 6 each morning and the following morning it has gone down to about 2.0-2.5 powder test, so I add about 1 gallon of LC. Getting expensive, but OK if that is what I have to do. However, this morning when I measure again the FC=2...

FC= 6, CYA= 40, PH=7.8 Been religiously following TFP this year and so far so good. Only use LC, but when I am away for a few days at my cabin, I have to use tablets. Trying to minimize there use so do not increase CYA much so trying to determine how much to put in to dissolve while I am away...

I know that it makes no difference, but just curious to know. I cannot find anything about the units of our measurements. For example an FC=6 is 6 what? is that ppm (parts per million), ppl (parts per liter). and are all measurements the same units eg. PH=7.8? Thanks if anyone knows

Finished SLAM and all good now, but with CYA 40, TA 100, PH 7.8, 22K Gallon pool, I am trying to get my pool to FC to 7 each morning but it is taking almost 1 gal of LC 10% to achieve. Seems high (and expensive) any recommendations?..or I just have to live with it?

I just finished my slam after 3 days I had 0 oncl and 0 CC this morning. FC was at 17, but later in the day it went down to 9. I also had a little bit of CC maybe 0.5. since my slam is done going from 17 to 9 seems like a lot of loss of fc and I was wondering does fc drop faster when it's at...

I cannot find the TF-100 test kit on the Taylor site and Amazon shows it as "unavailable". Did they discontinue it, or perhaps change the name?

I have a pool that is about 45 years old. About 20 years ago I had a lot of stains and the pools looked old, so I had some work done. To be honest, it was before I knew about TFP so I was not so aware. I think I had it sand blasted and resurfaced, not acid washed, but frankly not even sure...

I am adding pucks to get my CYA up from 30 to 40, as I am adding several my FC is maintaining around 9ppm. As warm weather is approaching is 9 ppm too high to swim in?

I am still learning. I have just a couple of small algae patches this winter, but now I learned that I was not skimming properly and had my FC too low. I have now increased my FC to 4-6, with CYA of 30 (increasing that slowly to 40 as per suggestions here with pucks). My CC =0. So far so...

Hi, I have been following TFP for a few year, but experiencing algae on occasion. In closer study, I see that I have not been holding my FC probably high enough because I had very high CYA. I have drained the pool and now have CYA at 30, and try to keep FC at 4-6 (CC=0). It seems to be taking...

OK, I know I will take a lot of grief here, but not sure what everyone has against test strips. Yea, they are not perfect by themselves, but: when FC is a bit high, PH test seem way off on drop test, cannot distinguish the color, but test strips seem accurate when FC is above 5 cannot tell...
