Seachem Flourish Excel 500 ml

I purchased this product after some plants I had bought introduced black beard algae to my aquarium. I tried a couple of other products prior to this with no luck. I tried spot treating with Hydrogen Peroxide and while that did seem to work, it was too difficult to use. I had the algae all over the tank to the point that the Hydrogen Peroxide just wasn’t a practical solution.I’ve been using the Flourish Excel for about five weeks now. After maybe ten days to two weeks, it had basically eradicated my algae problem. I still have a couple of spots of green or brown algae here or there – but it’s exactly that, just spots. I suspect the Flourish Excel works better or worse on different kinds of algae (as it completely destroyed my problem Black Beard algae) but even on the algae that it doesn’t completely take care of, it certainly reduces it and holds it at bay.Additionally, the plants seem to love it. It took a couple of weeks before I noticed substantial enough plant growth that I was sure it was because of the products and not simply regular expected growth from the plants naturally. I have been using this product in conjunction with a shrimp safe liquid fertilizer and my plants have benefitted greatly. My Amazon Swords in particular have tripled in size since starting this product with the liquid fertilizer.Very pleased. Great product, with no side effects to the fish, snails, or shrimp and crawfish in the tank.
