Review: This product really does clear out algae fast! - This stuff is amazing! I have a 40 gallon freshwater tank with lots of tropical fish in it. My tank is well established, but I've been having some issues with algae growing on the tank decorations and on the glass. I do water changes about once a week, I also have a very good quality canister filter. But managing the growth of algae was a major problem. So I bought a bottle of the Algaefix and I used exact as directed on the bottle. Within a few hours my tank was crystal clear. I couldn't believe how fast and efficiently it worked. I'm happy to report that all of my fish are doing very well. This product did not harm them at all. I definitely recommend this to anyone who's having an issue with too much algae growth, just be sure and follow the directions on the amount to use.
Review: Works Great - Works great! This has been the best solution to the algae in my pond and on the rocks in my waterfall without harming my fish! Highly satisfied!

### ⭐⭐⭐⭐ Great stuff; works well with no adverse effects
*by T***M on July 18, 2025*

Works better than any other product I've tried to control various forms of algae in a 3000 gallon pond. Water gets and stays clearer than I've seen it previously when using other algae control products. I don't have any fish to be concerned about but it hasn't harmed any of the water lilies or other pond plants. Only downside is for me it can be a bit expensive if I use as much as the directions say every week, so I'll often stretch out the applications to a lesser frequent schedule and I've found a frequency that works well for my situation.
