Dyroe Seachem Flourish Excel Bioavailable Carbon

We got this to address black algae that must have come in with fish or plants and was taking over our aquarium. Took a few months of daily additions but finally got rid of it. Now just add when we’re doing the water change.

The product is awesome for aquariums with plants. Helps with color of red plants. Bonus is if used every second day 1 cap for every 30 gallons it prevents slime algae and DOESN'T kill shrim

Had an outbreak of Blackbeard algae. Researched it and found that this is good for the plants and kills that stuff. The algae turned red and died. My plants are flourishing. Delivery was quick.

Our fish tank plants were not growing. Found this and it has made a HUGE difference. And it also killed off all the blackbeard algea in the tank, which is a big deal as it was massively over growing.

Not gone yet but controlled. I use 5ml per 20 gallon.
