We have an old (15-18 year old) Hayward pool heater that has stopped working and we need to buy a new heater. What factors should I consider when buying a heater? My husband would like to replace it as soon as possible (my daughter's birthday party is in 3 weeks) and has ruled out solar because...

Hi Richard, when the CH started climbing, this was my first guess too. After we did the R/O, the CH was under 200 and the fill water was 280. Over time, we'd expect the CH to rise, but not this fast. Where else could the calcium come from? It really makes me wonder if it didn't just dissolve off...

Thank you. I was wondering about this as Bruce also suggested it to me. I don't understand how a leaking pool could contribute to a rise in CH (not saying that it wouldn't, just that I don't understand it). I was thinking the opposite might happen since high CH water leaks out and is refilled by...

Greetings from Dove Canyon! Yep, that's my pool--went from under 200 in May when we did the R/O to 650. I've been meaning to post but have been super busy. The water in the pool is perfect and very consistent--levels for salt, borates, cya, etc have not been fluctuating. It's only the CH, which...

Thanks, everyone! I'll try the plastic bin and see how it works.

Re: Update on R/O (was New - High CH) It has been a few months since I posted these questions and I wanted to give you an update. But first of all, thank you to everyone here at TFP. You are all so helpful and generous. It is such a relief to understand what is going on with the pool (at least...

Thank you everyone. I will look into the R/O treatment and let you know how it goes. -- Karen

Hello, this is my first post. Last summer, we bought a house with an IG pool so we are fairly new to pool care. There is scaling above the water line on the tiles. I also saw a half-dollar sized hard bump below the water line. I just received my TF 100 Testkit and the results are as follows: FC...
