Last month CH was 325 Last week CH was 350 Today CH is 375 (tested twice with same results) What's causing it to rise? Pool was re-plastered on May 2nd and all my numbers have been in range but now CH is rising:confused: Added couple trichlor tabs to bring up CYA few weeks ago but it shouldn't...

How long should I run pump after adding bleach in the evenings? Thanks...:)

TA was at 70 and set goal at 80 on Pool Math. Added the 1 pound 12 ounces of baking soda Pool Math said to add with pump and APC running tested an hour later now I got TA of 120. What's up with that?

After having pool re-plastered 3 months ago I just noticed a stain. (See Pic). What caused this and how to get rid of it? My numbers have been right on the money since re-plaster and I brush twice weekly and treat it like a new born baby. No iron or copper detected with test strips. The stain...

Went to pool store today for case of MA so decided to take sample water with me to get a laugh. A month ago they said my CYA was 90. Today they say its 45. How can it go from 90 to 45 without partial drain and refill, haha They said my PH was 8.0. I checked before going to store and it was 7.5...

It was a beautiful day here in Dallas & HOT!!!!!

From Dallas,Texas,hope everyone has a great 4th of July weekend. Be safe!!!:D

I use 10% chlorinated liquid purchased from Lowe's with good results. Test hold true after adding. My daily cost of adding it is around $1.29 daily (adding around 5 cups daily) I'm losing about 2 to 3 ppm daily with only 0.5-1ppm lose overnight. CYA around 30-35. Thinking about bumping up CYA...

Was wondering what would make TA go up from 90 (yesterday evening) to 110 today? Only thing I added between test was little bleach last night. Today's readings FC 3.0 CC 0.5 PH 7.6 TA 110 CH 250 CYA 30 BORATE 45 Temp 82 degrees and sunny

Just got my new TF-100 kit and Speed-Stir in mail today and ran all test with it. Then ran all test with my Taylor K-2006 kit. Everything is really close except for the CH. TF-100 read 275 Taylor K-2006 read 220 Pool store tells me 183 Replastered a month ago and the pool sparkles like diamonds...

Pool sparkles like diamonds, numbers are spot on, but when I test CYA (Taylor K-2006 kit) several times with same sample I get a 30 then a 40 then a 35. Pool store tells me its 60 haha. This is one of the hardest test to determine where you really are with CYA. I run test just like Taylor video...

Just purchased 4 gallons Pool Proof but before adding I was wondering what would happen if levels falls below 30ppm or goes above 50ppm? From what I read it doesn't raise anything like CYA or CH Have done lots of research on the product and really can't find anything negative. Suppose to...

New pool owner for only 6 months now. Here is pic of my pool showing skimmer locations (2) and (4) returns with clockwise circular pattern. It seems to be doing good job with water just breaking the surface. Is this the correct way? Thanks

I just signed up as Lifetime Supporter. I see it as a $30 investment that will save me $100's from going to pool store, ha Pool owner for only 5 months now and I have learned a ton from this site. Really proud how the pool is looking right now. Thank you all....

Here are my test results FC-4.2 PH-7.4 TA-100 CH-220 CYA-40 Temp-80 degrees Pool Store test results FC-2 PH-7.8 TA-100 CH-250 CYA-60 Temp-80 degrees I noticed in some of the test the pool store doesn't add drops but squirt's solution in test tube, ha Think I trust my test more so than the...

Had pool re-plastered just over 2 weeks ago and now that all dust has cleared (with lots of sweeping) and water chemistry is balanced with super clear water I decided to try it out after doing yard work yesterday in 89 degree temp here in Dallas. Water temp was still little cool at 80 degrees...

At bottom of calculator is has Suggested FC Levels SWG:2 Normal:3 to 7 Shock:15 Mustard Algae Shock:24 What do these numbers mean and when are they applied? THX

Bought house with existing pool 6 months ago. Just got it re-plastered & added 25% blue quartz and also added marker tiles on steps along with new Deck-O-Seal. Looks awesome now that all plaster dust has cleared. Went strictly by Plaster Council instructions on what to do starting with fill day...

Should the Flow-vis flow meter be installed on inlet or outlet side of my pump filter? I have no room on inlet side so hopefully it will function properly on the outlet side of filter. Thx
