With the addition of 50 ppm of Boric acid two years ago, the battle was lessened. However, this Spring I'm back at it again. My TA is 50 and my pH is 7.8 - both at the extremes of acceptability according to the TFP "Ideals". The rest of the chemistry is as follows: CYA: 62 FC: 6 CH: 270 Salt...

Back in late July of this year, I ordered this test kit as my digital photometer only had an upper range of 8.0 ppm. I have not had good results with the Taylor kit and it's only getting worse. Today, I did a test with my digital meter and it gave me an "Over Range error" (>8.0). I then did a...

Just over two years ago, I replaced all my pool equipment - pumps, filters, the works. The attached picture shows rust staining on a "Stainless Steel" band inside a Pentair "Clean and Clear Plus" 4 cartridge filter. I clean the filters twice a year. The rust has been getting worse. Pentair...

I have only one full Summer under my belt and I expected I could follow the same pattern and levels of SWC generation this Summer. So far, that is not true and I am suspecting a problem. In early May, the pool was a bit cloudy and the Chlorine level was down to 1.2ppm. I cranked the unit up to...

I have found that adding Calcium Chloride to a large (Lowe's) bucket full or water and stirring it until it is totally dissolved and then distributing it around the pool, to be a real pain. Someone suggested a skimmer sock or something that can fit over the mouth of a skimmer basket that has a...

As this is the beginning of the pool season, I check my chemistry about every week unless we get heavy rain (Note This). Last week my FC level was at 1.5 so, I increased the SWG from 30% to 40%. All other chemistry was inline with recommendations. I keep my CH between 280 & 320. CYA 65 - 70...

I have a Pentair Ultratemp 140 Heat pump (140,000 BTU, 230v @ 50amps) and a Pentair 400,000 BTU natural gas hearer (4 Therms per hour). My current cost for electricity (just electricity-no other fees) is $ 0.145640 per kWh. My cost for natural gas is $1.296980 (just gas - no other fees) per...

I am still fairly new to pool chemistry. However, I think I understand that Salt, Calcium Chloride, Cyanuric acid, and Boric acid levels should not be depleted unless there is a leak and fresh water is added to bring pool level back up to normal (dilution) or heavy rain with overflow and...

I am still relatively new at pool ownership. I maintain my chemistry pretty well with a specific eye on CSI. My main question is if I maintain FC at between 2-4ppm, CYA 70-75, and TC has never been higher than .1ppm above FC, do I need to shock my pool? If so, how often, what type and amount of...

As a relatively new pool owner, I have been fighting the alkalinity/pH balance for close to a year. As someone wrote to me, "Adding Muriatic Acid and Baking Soda at the same time is like putting your foot on the gas and the brake at the same time!". He was right. It's all about the CSI. I...

Per recommendations, I added Boric acid late last Summer to 50 ppm. It really helped me do a better job of balancing the pH & Alkalinity. However, it is still an issue. I have re tested the Boric acid level, added 5# about a month ago and I'm back to 50 ppm. A few days (5/11/22) ago my pH was...

I have looked thru this forum and have found several old (closed) threads about this product. I am in need of something to remove calcium scale from my pool. I have been scraping off the heavy stuff, but now need something to get the last bit off. I have tried Muriatic acid (full strength), but...

I have been using PoolMath (paid version) for several months. It seems like a good tool for maintaining my pool chemistry. One annoying thing is that the calculated CSI is not saved with my logs. Why is this?

I just bought a 7# bag of the stuff (SunCoast) at my local Pinch-a-Penny for $50.00! It has gone up $10.00 since last August. Amazon has a 25# box of "Rx Clear" for $83.00. Where is a good source of CYA?

Yes, I have read numerous threads in this forum on the subject and yes, the pool supply guy recommended daily "two times" turnover. I'm guessing this is to sell more supplies. I live in Ocala, FL and have a good sized pool as you can see in the signature block. I also have a screen cage. I...

TFP has recommendations for pool chemistry. Fine. However, I was looking at my new Pentair gas pool heater's recommendations and they don't mesh. Plaster pool, Saltwater generator Heater TFP pH - 7.4 - 7.6 7.6.7.8 Alkalinity...

I have decided to add Boric acid to my pool. I purchased the LaMotte 3017-G Borate test strips. My problem is that the colors between 40 & 50 are very similar. I think I'm at 40 and targeting 50. Is there some test that I can do that doesn't cost a fortune? Local pool supply houses don't...

I am a 74 year old retiree. I recently purchased a house with a 11 year old pool (~23,000 gallons). I have completely replaced ALL the equipment, pumps (5), filters (2), heaters (2). and Chlorine generator. All are Pentair. I was getting mixed results getting pool water tested by one...
