Hello! I've recently started using Hasachlor 12.5% to see how it would compare to the pool Essentials 10%, and I'm not sure if I'm just not understanding the difference between the two, but I can't seem to get the chlorine to 5ppm with the gallon of Hasachlor compared to how I get it with...

I ran the overnight chlorine test last night. Last night's FC: 3.5 This morning: 2.8 After these results, the water is fine, and the CYA contributes to the low chlorine. However, the more I think about it, I think that I may not have rinsed the 1st gallon of stabilizer as well as I should...

I appreciate all the guidance that has been provided. Unfortunately, I'm still having issues with the FC. here are the numbers as of 10 minutes. FC: 2.5 TC: 3 CH: 300 TA: 80 CYA- less than 30 ( water was just slightly cloudy on the CYA test tube) PH: 7.9 I added a gallon of liquid chlorine...

I added more liquid chlorine last night and was only able to get it to 2 PPM. I also added some more early this morning before the sun was out to get it to 5 PPM based on a CYA of 20, and I'm back at 0. The only other chemical I added after the chlorine ( 1 hour after) was calcium increaser...

I was only able to buy the liquid stabilizer; they didn't have the granules. I added a gallon yesterday and half of another today. I've also added liquid chlorine since yesterday, but the test is reading 0 for chlorine even after adding some. What can be causing this?

Thank you! I will try a light application of the MA.

It is a pebbletech pool and the area is close to the spa spillway. The only other material around the area is the travertine pavers.

I forgot to add the PH of 7.8

Hi, I'm hoping to get help on an issue I'm having with the calcium deposits that we are getting on our pool tiles. According to the poolmath calculator, I think the chemicals are all within range, which is what's causing me to be confused as to why this is happening. I use the Taylor pool...

the pool is only two years old- what would you recommend I do? Should I contact the PB?

Hi, I recently started trying to maintain my water chemicals. We used to have a pool service company service it but weren't happy with their service. We also started noticing white blotches in the plaster in the center of the pool, but in the recent month or so, it has spread throughout the...

Hello! I've recently started trying to maintain our pool chemicals, and I need some help. Yesterday, our pool was not reading any chlorine. I went to the pool store and was advised to add shock to the pool which I did. We currently use the Sutro testing cartridge, and this morning it was...
