ecoBAK PLUS bio pellets are a unique multi-Polymer, multi-Carbon media that reduces Nitrate, Phosphate, undesirable algae and organic waste.

ecoBAK PLUS is a blend of biodegradable polymers that serve as a stable and consistent organic Carbon source, a food source and substrate for bacterial strains that consume organic compounds. ecoBAK PLUS reduces nuisance algae, clarifies water and supplies Planktonic bacteria as a food source for corals in the reef aquarium. ecoBAK PLUS works naturally with NO harmful chemical additives.

Compared to the standard ecoBAK, the ecoBAK PLUS is more aggressive and faster acting. The greater resulting bacterial diversity will result in elimination of more nuisance alage incuding Cyanobacteria.

EcoBAK PLUS requires the use of a properly sized and efficient protein skimmer to export the additional waste produced as the EcoBAK PLUS cleans the aquarium. EcoBAK PLUS is most effective when used in a fluidized media reactor with the output directed into the same area as the protein skimmer intake.


Use 250ml per 50 gallons of water volume. Rinse the ecoBAK PLUS pellets in purified fresh water. The pellets can be soaked overnight to reduce floating pellets. Add the rinsed pellets into a fluidized bio-pellet media reactor. Attach a small pump to the reactor and adjust flow to approximately 100gph per liter of ecoBAK PLUS. The proper amount of flow will create a gentle tumbling effect inside the reactor. Direct the output of the reactor into the same area as the protein skimmer pump intake. Within 3-4 weeks the ecoBAK PLUS will be sufficiently colonized with bacteria to begin reducing organic compounds. Aquariums with high bio-load may experience a short period of temporary water cloudiness.

Tips for best performance:

Start off with 1/3 of the recommended dosage of ecoBAK and add another 1/3 every week until a full dosage is employed.
Remember to run a GENTLE tumble. An overly aggressive tumble is counter productive.

Aquariums with very high Nitrate and Phosphate (Nitrate 40ppm+, Phosphate 2ppm+) should start off slowly, with 1/4 dosage of ecoBAK PLUS, confirm proper function of protein skimmer and confirm that circulation pumps are running and agitating the water surface.

Make sure your protein skimmer is properly rated for your aquarium. Protein skimmer manufacturers frequently exaggerate the capacity ratings of their skimmers.

Replace ecoBAK PLUS as it is consumed by bacteria.

Seems to work very well

I've struggled with Nitrate in the 20-40 range for a little while. (Regular 25-30% water changes, pre-rinsing food, trying not to overfeed.) I had tried original ecobak a while ago but my Nextreef reactor worked poorly for biopellets (Uneven flow, clumping, etc. even without the sponges in place) and I just had a slimy mess. Not wanting to change the reactor, I used some de-nitrate from seachem with a low flow rate and growing some different macros in the sump. Didn't have a lot of success with those either. So, I recently bought a hydra aquatics bio pellet reactor and tried the ecobak plus. Sounded like it was even better and faster working than the original. My nitrates were in the 20-40 range when I started and I went ahead and started with the full dose for my tank size and turned off my UV. Within the first week I had cloudy water but it was gone in under 2 days. I'm now about 2.5 weeks in and my Nitrate level just tested less than 5. Water is clear and I don't have to clean the glass nearly as much either. When they say to have a well sized, working protein skimmer, it's no joke. I get twice as much crud in the cup as I used to. Overall great product.
