Seachem Flourish Excel Bioavailable Carbon - Organic Carbon Source for Aquatic Plants 2L

Seachem is simply the best. All my aquariums are heavily planted and this is a staple for them

A very useful additive for live plants

This aquarium supplement helps keep my aquarium plants lush, while discouraging algae growth. It’s much easier than maintaining a CO2 system, and at 5ml per day for a 55 gallon aquarium, it lasts a long time. Good value for money.

All Seachem products are high quality and this size will last a really long time. The dosage is a bit confusing but with some research you'll figure it out.

Absolute must have for anyone keeping live plants in an aquarium. Excel helps your plants grow and out compete algae keeping everything healthier and more attractive. You could of course go with a hi-tech CO2 injection system, spending much more money and time but for most of us his is the best way to help get extra carbon to our submerged plants.

I don’t have a co2 tank and just use this. It’s been over a week now and I can already see the difference it’s making on my plants. It even saved some from melting and now they are back to green again. I have 7 fish in 10 gal tank and they are perfectly fine. I do like 1/8 of the cap daily. One star off because it hasn’t stopped all the algae growth.

This product worked wonders for my tank. I had battled black beard algae in the past but didn’t realize the root cause of it fast forward to now, I had moved and set up a new tank and started having the same problem again! So I started researching and it led me to realize my planted tank was lacking CO2. I had recently added more light and my plants started taking off tremendously and the BBA started to appear. I decided this was the product for me vs an actual CO2 line. I followed the directions and upon the initial dose (my tank is a 54 gal corner) it did make my water appear white and hazy even after a water change. I have a community set up from corydoras, oto’s, platies, nerite snails, dojo loaches and khuli loaches. All my fish handled this product well except my corydoras. I have a had time keeping those as is but those were my two survivors that I managed to keep alive and I believe this product did cause them pass. So just note that they may be sensitive to this product. I still give this 5 stars though. It did as it said and my tank is looking fabulous again!! It took about 2 weeks to clear up an minor infestation.

Great carbon for tanks. I use in a heavily planted tank that isn't supplemented with CO2 and it does the job.
