    Calcium Hardness

    What is the most cost effective way to increase calcium hardness? We are getting a lot of rain here in Houston and it been getting expensive to maintain the proper calcium hardness levels (250-350).
    I live in the Albany NY area. The size of my pool is 24,000 gallons. The pool is an In-Ground rectangular Double Roman with a vinyl liner. I am using a Taylor K-2006 water testing kit. I have a DE filter. I have a regular chlorine pool. The pool cleaner is a 2017 Dolphin Premier Robotic In-Ground pool cleaner.

    I am in the same boat. I just added 5 pounds and it brought me from 210 to 250. Had to add a lot of CYA also. You can purchase calcium increaser at Walmart. Below is a link to Amazon for the same thing. My wife said Walmart was the cheapest she found.

    Lowe's sell a 50lb bag of calcium chloride for $ 18.97. This seems to be a much more cost effective approach to increasing calcium levels. Do you know if it is OK to use this product?

    Morton sell it as ice melter but you are so far south I doubt you have a need for ice melter.

    You can check the where to buy on that page, maybe a local hardware store can order you a bag from their warehouse? Ace hardware maybe? walmart ship to store?

    Yep, we've got the same problem. Rain, rain, rain. After we dumped 110lb of salt in, it poured and we had to drain water off! GRRRRR. AND I agree, that calcium stuff is expensive. it costs us $50 each time. Can we use calcium whatever from Lowe's????? anyone?

    Troublefree does not mean Maintenancefree. It's like brushing your teeth: You can spend a couple minutes a day and pennies a week or go to the dentist once a year and spend several thousand dollars.
    A pool is like a pet - you have to feed it every day, even the days you don't want to play with it!

    Re: Calcium Hardness

    CH has been dropping the last 2 months with all this rain. Started out at 375 when i first got the TF-100, now down to 325 this weekend. Tested the fill water and found that there is almost no calcium in our water. One drop and it changed color. So in the near future we'll be needing to add calcium to keep the pool balanced. Just one more thing to keep an eye on in having a balanced pool. CH up, Ph down and FC steady is going the be the summer program. Oh, and keep the trash that the wind and rain keep putting into the pool out
