Review on 🌱 Seachem Flourish Excel - 2L Bioavailable Organic Carbon Source for Aquatic Plants by Dawn Bunger

This is a great algae killer for a planted aquarium. If you fertilize your aquarium regularly then you know that algae is a problem. Algae can absorb nutrients and carbon dioxide better than most plants. So it's not so much liquid CO2 as it is a product that controls algae and allows your plants to utilize the CO2 and nutrients consumed by the algae. That. I don't recommend the large starting dose that is listed on the bottle. I use the normal dose every day (75 gallons = 1 full cap. I've even used 2 caps when I've been lazy and not dosing which allowed the algae to get out of control. This keeps my plants thriving along with fertilizers like thrive and thrive iron It is also great for spraying directly on concentrated patches of algae, just put the normal dose in the syringe and spray the algae directly DO NOT SPRAY DIRECTLY ON PLANTS Algae Control This works very well as it produces almost no algae.
