HorizonHV-SB2PK Scumball Pool and Spa Scum Eliminating Ball (4 Packs of 2)

I was skeptical. Put one in our hot tub and was pleasantly surprised. The water is crystal clear. I would definitely recommend for your hot tub especially if you don't like to shower every time you get in.

We love these balls, they work extremely well, and are quite inexpensive for how well they work, great value.

Of course my return window had closed by the time I got to try my latest order. These are junk- they turn orangish brown immediately and are lighter and a different material that doesn't absorb anything. Amazon is now selling counterfit products, just like Chewy. Buyer beware!

I have been using these for years in our pool. While they are effective and I have always liked the product, I cannot believe how the price has escalated! I bought the four, 2-pack option. The price works out to more than $7 per scum ball - which is ridiculous. I gave them a single star for easy to clean because you are not supposed to clean them. You are supposed to dispose of them and use new.

I don't understand. The previous 6 orders were fine. These are textural different. Very soft and turn brown after a few hours. The others would stay white for weeks before needing replacement and much firmer.

These are not the same product. Missing the outer white coating that soaks up the scum. Material is just a round piece of foam that just sinks. Please bring back the original balls.

These turn yellow after the first day. We ordered some last year that were awesome and thought these were the same brand but evidently the are not.

Way better than the turtle and other thin shaped ones.

Did not work as advertised. Put in clean/balanced hot tub and in 2 days were completely brown and heavy! Supposed to last a month. Went out and bought a zorbie ... for comparison, after a week, zorbie still almost dry and floating on top.

Purchased 2 packages of these. Have used them before with no problems but the product from both packages turned brown within a couple hours in new, clean and balanced water. Attempted to contact seller and no response. Do not purchase.
