I have used this shock a couple of years now and have found this product to resolve quickly and is easy to use. The product does help to slow the growth of Algae as I live in the South. It does work well with GLB Algae products. Of course, the price is very competitive when bought in bulk and the service was excellent!
GLB SuperSonic is a highly effective multi-purpose product that sanitizes, clarifies, prevents algae and shock treats your pool. It is convenient, easy to use and won’t over stabilize your pool water. The fast-acting formula can be used on all pool surfaces, does not contain cyanuric acid and leaves no residue.
- Easy to use
- Will not over stabilize your pool water
Every 7 days, or as necessary to prevent pool problems, shock treat/super chlorinate the pool by adding 9 to 18 ounces of this product per 10,000 gallons of water to provide 5 to 10 ppm available chlorine. Additional shock treatments may be required to correct problems which are caused by visible algae, high bathing loads, heavy wind and rainstorms. Additional shock treatments may also be required to correct problems such as unpleasant odors and eye irritation. Check the available chlorine with a suitable test kit.
Follow "SHOCK TREATMENT" directions on this label. Add this product as close as possible to any algae on the sides or bottom of the pool. If necessary, repeat the treatment. To prevent possible staining or bleaching, take the following steps immediately after treatment: Thoroughly clean pool by brushing surface of algae growth, vacuum and cycle through filter. For preventative algae control, use your preferred algaecide product regularly. Follow label directions on the algaecide.
Additional shocking to keep water clean and clear is recommended after rain and heavy winds, high number of swimmers; increased water temperature and/or increased frequency of pool usage.
The fast-acting formula can be used on all pool surfaces, does not contain cyanuric acid and leaves no residue.
The best product for all your pool cleanup needs. Will definitely purchase from MKM again.
I was searching for a chlorine shock product that does not contain stabilizer. Here in drought stricken California pools get oversaturated with cyanuric acid, reducing the effectiveness of chlorine. This product meets the need, at a good value price, shipped promptly.
