Fishtank stuff
Great price compared to Petco, Petsmart and the usual fish stores. My husband uses this in both his aquariums to keep the water fresh and decrease the algea.

Works very well
Plants really take off after using for a couple days. Algae died off and isn’t able to take hold. Great product when used accordingly. Makes plants super healthy and will need to also make sure you give the plants root tabs to keep up the health and size.

It works, and adding a bit to each water change keeps the tank happy!
I have a hundred gallon freshwater aquarium with planted plants, and Flourish Excel was recommended by a friend who owns an aquarium store years ago. It really helps keep the plants happy. I highly recommend it!

Good product
I used to have algae problem. So I started using this product every other day and now all my algae problem went away. It really works. But warning, my vallisnaria plants don’t like it, they all died. But it didn’t affect my other plants, they all thriving. Once my small bottle was finished I ordered this bigger bottle to have more for a better price.

Great product, works as expected. High recommended for spot treating BBA.
Been using this product for 20+ years, its great for supplementing CO2 injection or dealing with black beard algae. Never hurts my fish or snails. Good quality as always. Super easy to use. Lasts forever.

This product works very well for promoting healthy growth in aquatic plants. I’ve seen noticeable improvements in my tank since using it. The formula seems effective and helps keep plants vibrant and strong. That said, it does require regular dosing to maintain results, so consistency is important. Overall, a solid choice for anyone looking to enhance their planted aquarium.
