Another great product!

[This review was collected as part of a promotion.] This did exactly what it was meant to do which was to keep the calcium levels up. I’ve said in previous reviews that I’ve used the product in conjunction with others in their line. And I was able to see a huge difference in our pool this summer.

Works great

[This review was collected as part of a promotion.] I love this product it allows me to maintain my pools health as the summer goes on. We have a pretty healthy pool but this product makes it so much easier to keep it maintained and safe for my kids to be in the water.

REALLLY Good with this Water Levels!

[This review was collected as part of a promotion.] I like how this worked with my levels in the pool. I could tell a HUGE difference in my water once I used this! the water definitely was not as hard as before. This leveled out the roughness but didn't make the water too soft but it was just perfect for us after this usage. I would say that after cycling this through the system, it took longer than I expected it to to work but it was great afterwards.

Great Pool Chemical System

[This review was collected as part of a promotion.] I have been using the HTH chemicals for a few seasons now and they work great to keep the our pool clean and crystal clear. They are easy to use with easy directions to follow to help get my pool water in balance.

Keeping my pool surface in tact!

[This review was collected as part of a promotion.] Calcium is so important for the pool’s surface and for the equipment. I have learned just how important in regards to keeping the level balanced for maintaining and prevention of corrosion of the pool’s surface and so important equipment. I have seen first hand what not keeping it in balance can do and it isn’t pretty. Literally the pool’s surface will eat away at its self. It is awful. With the HTH calcium, I can maintain a sparkly pool and h...

Great product

[This review was collected as part of a promotion.] I am enjoying using HTH Pool Care Calcium Up, which raises calcium hardness, and is a swimming pool chemical that protects swimming pool surfaces and liners, and it helps prevent corrosion of pool surfaces. It is compatible with chlorine, salt water pools, & vinyl-lined pools too! It helps protect and prevent corrosion on pool liners, metal, and plastic surfaces, along with equipment from damage.

Great!

[This review was collected as part of a promotion.] I would definitely purchase this. It helped keep my pool clean and clear. It wasn’t cloudy at all. I would definitely recommend this to anyone who needs it. I would buy it again for next summer when the pool is open again.

HTH Calcium Up

[This review was collected as part of a promotion.] Calcium is one of the most often overlooked pool chemicals, at least at my pool. I never really understood what it was for until I did a little research. Low calcium can cause damage to both vinyl and plaster pools. The pool water apparently seeks out the calcium it needs and pulls it from where ever it can. In plaster pools it will cause pitting, and in vinyl it will cause it to be less elastic and supple. So basically shortening the life o...

Pool calcium pool care.

[This review was collected as part of a promotion.] I was able to receive some HTH pool calcium. Just was we needed for our pool out here in the country will well water. This builds the hardness of the calcium level. Making the pool easier to maintain.

It works

[This review was collected as part of a promotion.] We have a large above-ground pool and have to use a large amount of calcium hardness every year. This product works well, but for the price you receive 4 pounds, which is comparable to spa brands put a little pricey for a swimming pool. Our water is generally low in calcium so I have to add calcium during pool time. I tested this is made in the USA calcium chloride Calcium Increaser on our pool and found it dissolved quickly. I was worried t...

Great Product

[This review was collected as part of a promotion.] I recently acquired this product and I am so happy that I did. I used it for my pool and it did exactly what I wanted it to do. It drew moisture from the chemicals. It was exactly what I needed and I definitely be recommending this product to my friends with pools.

Raises calcium levels and is safe for vinyl pools

[This review was collected as part of a promotion.] Calcium up is easy to add following the charts on the back of the bag. I’m not a professional at pool chemicals as I’ve had a pool for about 2 seasons now, and honestly didn’t realize I needed calcium to help with corrosion. I’ve found that the 4lb bag is plenty for my 10,000 gallon pool. Works well with my vinyl and salt water system.

Works great

[This review was collected as part of a promotion.] Ok definitely satisfied with this product. I live in an area that has high in calcium in the water and this definitely hekped balance that out. I have nothing bad to say about this product it makes my pool look great

Works well

[This review was collected as part of a promotion.] This HTH Pool Care Calcium Hardness Up works effectively, I applied and I was able to see the result the following day on my water tester kit. I have a 22ftx 12ft above ground pool with a 25000galon filter running 24/7. This product improved my water quality very fast. I have a clear pool now.
