Pool RX 332066 PoolRX+ Booster Black Swimming Pool Algaecide, Single Unit

My friend told me about this 3 years ago. I have used it at the beginning of the season and it has cut down on chemicals dramatically. I have a very large salt water pool and, besides the required salt, I only spent $68 on chemicals the entire season. No algae and sparkling clean pool all summer. Every time I went to the store to get my water checked they said I was all good. Excellent purchase and highly recommend. Will use the beginning of each pool season for years to come.

This is a good product, in my opinion. It cleared up my "algae bloom" in no time.

Works great. Been using it for about 3 years.

I had been struggling with black algae over the last five months. In the past i handled black algae by rubbing chlorine tabs on the spots, but this last summer was very warm and the black algae started to spread continuously. In the past it had been in grout lines and occasionally in my pebble tech. Then it started forming in my pebble tech and spreading slowly. I tried rubbing chlorine tabs on it, then purchased algaecide from Leslies, and Algatec from Amazon. I was wire brushing the algae several times a week along with the Algaecide treatments. The black algae was literally unaffected and got worse. I closely monitor my pH and chlorine levels, been doing it for 15 years, and was at my wits end. When you research they all say their product works, but I am very skeptical with my $$. After about two weeks, and only a little wire scrubbing, my black algae was gone! I'd buy it again, nuff said!

Kept algae at bay for 6 months but I have to treat my pool for 40k gal. So I use one regular black with one black booster. Wish they lasted a year for the price! Expensive

I like Pool RX vs the floating solar copper units. I am able to use Pool RX with 1-2 3" chloring tablets without using liquid bleach. BTW, never use liquid chloring pool bleach when using Pool RX, it will cause the pool RX minerals to fall out of suspension and stain the pool surface. Keep ph. adjusted and only use 3" chlorine tablets. Great stuff!

We tend to get mustard algae at the beginning of the season when the pool starts to warm. Our old pool guy recommended this product, and it works well to keep the algae under control. The sides still need regular sweeping, but the algaecide takes care of it once the spores are in the water column.

This product did nothing to remove the algae on the pool side walls The product dissolved quickly The product stained the pool walls and bottom blue
