Review: When we put our pool up many years ago we didn't have any great options that kept it away from trees. I had to either deal with the leaves falling off the trees into the pool or cut the trees down. I was not going to cut the trees down. Every year it seems I am having to deal with at least two outbreaks of algae growth in the pool, possibly due to the leaves falling into the pool. Before I opened the pool this year I did some research on preventing algae. What I found was make sure the pool water is stabilized, chlorine level is always kept at the proper level and all other required chemicals are kept at their proper level. I've been doing that every year but still got algae. This year I decided to use an algaecide along with regular chemical maintenance. I followed the instructions for initial treatment for my pool size and added that amount. I'm also adding 2 ounces to my 15,000 gallon pool every 5 days. A bit more than recommended, but to date I have not had any algae problems. And now that I said that I'll probably have an issue. :-) But it's getting late in the season for where I live, we close the pool right after labor day, and so far no issues with algae. I'm going to attribute my lack of algae growth to this product. The addition of this algaecide is the only thing that's changed from previous years when I was having an algae problem. And it's been hot this year and heat typically aids in algae growth. Product seems to be working well for me. It's worth a shot if you have algae issues.
Review: Have used this on my inground pool during summer months when I have problems w green algae. Clears the pool pretty fast. It does on occasion leave bubbles on surface for a day or 2 so recommend not using pool for 24 to 48 hrs. But it does clear the pool of algae

**Q: Does it contain copper?**
A: No, the HTH Pool Care Algae Guard Advanced does not contain copper.  If you are looking for a product that does contain copper, you will need the HTH Pool Care Algae Guard ULTRA.

**Q: How much to use for a 18x48  round above ground  pool that holds 6500gallons water?**
A: For 6500 gallon pool, you would need 2.6 oz initial dose and then .7 oz as a regular maintenance dose.   If you need additional help, feel free to call our Consumer Engagement Team at 866-484-7665. We're Here to Help!

**Q: So in Washington State we are not allowed to kill algae growing in our pools?**
A: That sounds ridiculous, but I'm not from there so I can't say whether it's true or not. But come on, I think they are concerned with run off when you drain or backwash your pool and the possible release of the chemical, but that's a guess. You'd have to contact your city

**Q: Does this contain any metal based ingredients?**
A: The HTH Pool Care Algae Guard Advanced does not contain copper.  If you are looking for a product with copper, you will want to use the HTH Pool Care Algae Guard ULTRA.

### ⭐⭐⭐⭐⭐ Review
*by D***D on 27 June 2023*

I'm located in FL and would constantly fight issues with my inground pool for the last 2 years. Daily I'd vacuum the floor and walls, change my filter for one that would get soaked overnight in muriatic acid and power washed the next day before the swap. Always green if I skip a day. This first picture isn't even at its worst. After using this brand shock as well as this product, chlorine at 4ppm and I use Arm and Hammer Clear Balance tabs. After 24 hours of shock with pump running, added this product and clear balance tabs, brushed and vacuumed walls and floor, water was cloudy and foamy, so follow directions to a T because anymore and I'd have probably had sludge build up. After 48 hours, nothing was growing back on the walls or floor, and 72 hours later, my water was crystal clear and still no growth anywhere. Of course still changed filter between all this. Second photo is now a week later, last night before this picture I added the maintenance dose. Every time I've pulled the filter it has way less discoloration and now I'm going to change it every 2-3 days and see what happens. Great product. Easy to use. Visual and fast results. Just follow instructions.
