Katalyst is a new Biopellet from Brightwell Aquatics which is a solid carbon dosing alternative for phosphate and nitrate control. Brightwell Aquatics is one of those companies which is happy to chase all manner of additive products (i.e. NeoZeo) and we’ve long suspected that Brightwell would soon come to market with a biopellet of their own. Whether Brightwell Katalyst “bioreactive filtration media” is a unique formula or just another repackaged biopellet product remains to be seen, but at least it’s nto coming in the nearly identical pouches of two lil, SWC, NP-Biopellets, vertex and on and on.
What is particularly interesting about Brightwell Katalyst is at least how it is being marketed for freshwater and saltwater tanks, compared to Warner Marine which is marketing their EcoBak biopellet media to low nutrients reef tanks using that god-awful acronym ULNS. yuk. Although biopellets are being closely tied to liquid carbon dosing like vodka which is more prevalent in high energy SPS reef tanks, you could argue that biopellets like Katalyst could be more useful on fish tanks with high bioload stocking, and nutrients which need to be reduced. Currently we’re only seeing Brightwell Katalyst listed for sale on the Depot’s website with 600 grams selling for $49 plus shipping.
