Algae Off Granular Algaecide

I’ve been using algae off for years, it has always done a great job.

Not always effective

My case may be unique, but my waterfall/stream completely drains on the upper level but retains a couple of inches of water on the bottom level. So some algae has good contact and some doesn’t, so I never get all of the algae killed; it always grows right back even when I also treat with the liquid D-solv

Clean/clear water

Got my algaeoff quickly and was able to kill and now control string algae. Thanks! Great family business.
