Q:We have a natural geothermal pool. will this work with Geothermal water?
by|Jul 21, 2023
1 Answer
Answer This Question

A:  Chuck, do you have signs of algae or are you simply trying to prevent? To confirm, the geothermal pool would have copper, correct? If there are metals in your water, (not sure), we can't say for certain it would not react. Please consider giving our Consumer Engagement Team a call at 866-484-7665 so we can get more information and help discern what's going on. We're available M-F, 9 AM - 7 PM EST.

    Answer This Question

    A:  Mary, thanks for the question. Our HTH Pool Care Algae Guard + Ultra does contain copper as part of the algae control. If you are looking for a non-copper algaecide try our HTH Pool Care Algae Guard Advanced, this treats green, black and mustard algae. If you need additional product information or help with your pool/spa care, feel free to contact us at 866-484-7665. We are available M-F, 9 AM - 7 PM (ET). We're "Here To Help!"

      [This review was collected as part of a promotion.] My Sister-in-law needed someone to close her pool for her so my wife and I went to her house for the weekend to close it for her. The pool was pretty green, but with a heavy dose of (HTH pool care algae guard Ultra) the next morning the pool was clear enough to close. So we continued to winterize it. I would recommend this HTH algae guard Ultra to anyone who has a pool.

        Works well
        [This review was collected as part of a promotion.] I live in an area with high humidity and periods of no rain and then days of rain, especially this summer. This algae guard works very well to quickly get rid of the algae that we've had happen and I feel it has helped prevent the occurrence of heavy algae problems. It does foam a little, nothing major, and I use just a small but of de-foamer and it goes away. I really like that we can use this and swim immediately. Very clear directions and measurement markers in the bottle.

          Excellent product
          [This review was collected as part of a promotion.] This HTH Algae Guard is excellent! I know sometimes you can feel hopeless when your pool turns green and cloudy and you can feel super discouraged and like it will be a lot of work. The algae guard is so amazing that it literally starts working instantly. It starts fighting the algae immediately and you can see it start to work. It only takes a few hours before the pool is crystal clear and it stays that way for a while before you have to treat again! I highly reccomend this product! Quick, easy, and effective!

            The Best
            [This review was collected as part of a promotion.] The high temperatures and heavy rain in Georgia makes my pool water very dingy. After using the test strips l used the HTH POOL CARE ALGAE GUARD ULTRA to help balance my water parameters. It worked well, the pool was restored to a good sanitizied level. The product workedquickly, had no fowl odor and the instructions were easy to follow. I will continue to use this product as a preventative algaecide.

                Quality product
                [This review was collected as part of a promotion.] So the HTH algae guard is definitely making a difference in the cleanliness of my pool. I use HTH shock first then the next day I add the algae guard and the sides and bottom of the pool clean up quickly.

                  Works well - just follow directions closely
                  [This review was collected as part of a promotion.] So I was on vacation and my pump quit working during a storm. So of course I had algae and my pool was green once we returned. I used HTH to get rid of the algae and along with the salt pump (salt water pool) and shock - I was able to get my pool back to swim able shape within 3 days - which is awesome. I have used HTH products but never before the long acting algae killer - so I'm hoping for some relief longterm! One week so far and it is still blue!

                    Will kill algae
                    [This review was collected as part of a promotion.]  I tend to sick with the copper based algesides because I know they work, during my last huge Algae bloom I tried everything else to get rid of it. The Ultra algeside is a copper based algeside and it's long lasting to prevent more blooms overtaking the pool. I didn't have to use nearly as much of the product as I thought, but my pool is rather large and it does require more product then most other algeside. It also says non foaming formula but as you can see in the pictures it did foam up. However the foam dissipated the next day and if works I'm fine with it. I plan to continue to use it more for pool openings and closing.

                      Maximum protection against algae
                      [This review was collected as part of a promotion.] This HTH® Pool Care Algae Guard Ultra is the maximum guard and protection against algae in your pool. This is the long lasting formula that lasts up to 3 months. While I do like using this, I was already using another formula in my pool, so I started using this in my parents pool. I like how I can add this to their pool, as I am the one that maintains their pool, and I don’t have to add it every week. This works long term. It has a tendency to foam a little, but it’s worth it to have the water so clear. They are happy with it, as am I.

                        Great stuff right here!!
                        [This review was collected as part of a promotion.] This product is the absolute best you can buy especially if you have kids who can’t wait to jump in the water..it’s very fast acting. It works up to 3 months which is great! The best part is you can swim with it in the water.. no waiting!! I would definitely suggest this product to others.
