Bio Beads/Pellets

[kien]

I have seen at least 4 different variations on these Nitrate/Phosphate reducing "bio pellets" now. I think pretty much everyone has started to jump on the bandwagon with their own take. I saw a few bags of the Vertex variety at Red Coral last weekend

- The "original" NP Reducing Bio-Pellets
- NpX bio beads
- Vertex Pro-Biopellets
- Warner Marine EcoBAK solid vodka dosing pellets

.. just to name a few. Oh, and Instant Ocean now has a "fluid form of Solid Vodka Dosing via Suspended Biodegradable Polymers" ???
