Review: Wonderful product for summer pool maintenance - I had what was finally identified as white algae sudden show up in my pool. I was not familiar with this infestation and had to do some research to figure out what to do about it. The local big chain pool company was not that helpful and was recommended 4-5 things to add all at once....seemed there had to be a better way, so, as I said, I did some research. I have a salt water pool so, I took that into consideration when deciding upon a treatment method. I also have grandchildren who live in the pool during the summer so, that, too, was a primary consideration. This product seems the best base on the eco-friendly biochemical formulation they use. It is a weekly to bi-weekly treatment for my pool, takes about 3-minutes, and is safe to swim in 15 minutes! Best of all, IT WORKS!!! After the first treatment I say immediate results. I did double the dosage the first treatment, but afterwards just have been following the recommended weekly treatment program. NO MORE WHITE GUNK showing up in the pool and the filters are cleaner, lasting longer as well. I do think the product is expensive but, based on the results, I will continue to use until I can no longer afford it. I have been disappointed to not be able to buy the single use containers, having now to buy the large bucket (always a pain to store these bucket bulk items due to floorspace consumption). However, I kept one of the single use containers and just fill it up prior to use and store the bucket remotely...works for me. I highly recommend this product for control of pesty algae and other bio related issues that show up in pools...great product! Review: Worth the cost - Used to have all kinds of algae problems in my in ground pool. Pool guy suggested bio shock and I have never had a algae problem since. Great for algae removal and prevention and overall keeps my pool looking crisp and clean. Expensive but worth it. Great quality and easily to use. Dissolves quickly with nothing left on the bottom. The best option that I have used. ## Features - Multi-Purpose Pool Shock Treatment: BioGuard Smart Shock is a multi-functional product that shocks, oxidizes, buffers, and clarifies pool water.
