This stuff is GRRRRREAT! GREAT, GREAT, GREAT. Between sprinkling this product, 1 cup of chlorine %26 sprinkling some drop out on the top of pool surface x1 a week, with a ZERO leaf %26 debris policy -- I AM able to keep my 40k pool CRYSTAL clear water clean on the REAL. I also have to vacuum the bottom x1 every 2 or 3 wks BUT I NOW NEVER RUN MY POOLS PUMP only to vacuum. NO OTHER, ZERO testing or chasing %26 buying %26 getting suckered into BUYING every OTHER "pool cleaning" NIGHTMARE fix that never worked! TRY this method %26 see if YOU don't cut your POOL owning %26 seemingly constant water maintenance down to ZERO!!! Hope this helps ALL pool, pond, tub or water puddle owners end the 8 year NIGHTMARE I've had before developing this "easy as 1-2-3... A, b, c, baby you %26 me..." (sorry bout that, MJ flashback)

Works Like A Charm! Goodbye Algae!

Cole November 12, 2025

The only thing I hate about this product is the price. Other than it costing so much, it works great. I have struggled with algae each summer since getting my pool and thins stuff clears it right up. After 1 bottle of this in the pool and some brushing, a couple days later my pool is crystal clear and looks amazing for at least a month. I know this says 3 months, but I obviously have some issues balancing my chemicals. I have had green and mustard algae and this has handled both with no problem. It takes the whole bottle, but this stuff WORKS! I have no doubt, if you have any amount of algae in your pool, this will resolve your issue. I will have to update my review next season when the algae comes back and I have to release this beast on it again.

Nip Algae in the Bud

Faye February 13, 2026

This product is a liquid, and I add half a bottle monthly to our in ground pool to keep the algae in control, before it becomes a more difficult problem to manage requiring lots of expensive chemicals.

Easy to use and Algae Free

Kathleen June 28, 2025

I received this product free in exchange for my honest review. The day we were preparing to open our pool, I received HTH Pool Care Algae Guard Ultra. It arrived in an easy to open bottle with clear instructions and enough product for 2 doses. My pool walls did have a little green so after brushing and vacuuming the pool I followed the easy instructions on the bottle. The grandkids were going to be swimming that afternoon and it said it was safe after a short time. Yay! There were no harsh smells, it did not even for a second cause a cloudy film so I got in and so did the kids. We could not detect any difference in the water, it felt great! It's now 2 weeks later and no signs of algae so I would say it's very effective and I'm happy with the product. The cost is reasonable so I will always have some on hand. @influenster @hthpoolcare %23complimentary %23HTHPoolCare %23HTHPools %23AllClearWithHTH

I began using this product this year and it made a tremendous difference in the quality of my pool water with far fewer use of any other chemicals. So it was very easy when I could order more of this to have on hand to close my pool and prepare to open it next year.
