aquavitro Biogen – 225 ml
aquavitro Biogen is a carbon-based biopolymer (PHA) that reduces nitrate and phosphate in aquarium water. You will notice an excellent improvement in coral colors as well as a decrease in nuisance coating found on aquarium rock and decorations. This product should be used in a fluidized bed reactor with a continuous flow of water to keep the beads active. Biogen encourages the growth of aerobic and anaerobic bacteria, which colonize on the beads within 2 to 4 weeks. Maintaining a clean, healthy, and visually appealing aquarium is made easier with Biogen, trusted by hobbyists and experts.

Does Biogen affect coral coloration?

Olivia Dowd –
I’ve used Biogen in my reef tank for three months now. The coral colors have become much brighter and the rock surfaces are much cleaner. I run it in a fluidized bed reactor with a steady water flow. It’s easy to maintain and works well with my existing setup.
Michael Metcalfe –
After switching from a chemical filter to Biogen, I noticed less algae growth and clearer water. The initial colonization took about three weeks, but now the system is stable and the water parameters are much better.
