Brightwell AquaticsReef BioFuel - Organic Carbon Supplement for Marine and Reef Aquariums, Aiding Bacterioplankton Growth That Promotes Rapid Phosphate and Nitrate Reduction, 250 ml

Been using this when it first came out. Worked

This product works well for natural nutrient reduction. I have been using for a long time. When used with Microbacter7, it will significantly increase the rate at which you see the nutrients drop. After nutrients are at a acceptable level - reduce dose!

It didn't work for 2 months dosing. I purchased bacteria, microbacter 7 because some people said I did not have bacteria enough. I have dosed more than a month based on instructions. The nitrate had never dropped. My case is wasting money and time. I tried vodka but nitrate is still the same. I will try red sea . Let see if it works.( update red sea no pox dosing )50 ppm dropped to 0 ppm for 3 months dosing. For two months 50ppm dropped at 5ppm. Vinegar, vodka and brightwell biofuels are certain type of carbon. Nopox has compound of all kinds of carbon. So this works with any kind of bacteria in your tank.

Great stuff. Used in my Waterbox 30 when I was cycling.

I have 3 systems ranging from a Biocube 29 up to a 225 US gallons predator system. I use only Brightwell chemicals in all of them. Excellent products.

perfect --our fish love it

Great. No issues.

Works Great For Me!
