We have a pond. After finding birds eat every batch of fish we try to supply we have decided on keeping it chlorinated. It's been years of trying to manage the algae with various products. This pool shock has been hands down the best solution. It does take one day to look clear after putting in a bag, but it stays clear 5x's longer! All these products are expensive, but this one does the job.

I ordered pool shock from another company last year, and it came with moisture in the packaging as well as some loose shock that caused the individual one lb bags to stick together that was very unsafe to handle. When I needed shock again, I ordered from Doheny’s. Their price was better, and the product was packaged better and shipped directly from the company. This is my second order from Doheny’s, and the product was perfect once again. They have become my go-to supplier!
