Nitra-Guard WITH BOMB kits in-stock

[mrhasan]

BIO-Cubes are made from 100% biologically degradable polymers that effectively remove both nitrates and phosphates from both marine and freshwater systems.

That's what biopellets are made up of. So, basically, these are just bigger chucks of biopellets* which can be used in mesh bags. I would say it is convenient for nano tanks And saves on the reactor.

*Reasons:
1. Both are made of biodegradable polymers
2. The bio-cubes have to be placed near a skimmer

Same methodology, different names
