Marine Phosphate Remover GFO (GRANULAR FERRIC OXIDE)nano pack 100ml
High levels of phosphate commonly cause algae outbreaks and can be damaging to fish, corals and other organisms.
Keeping levels low helps water quality and reduces many common reef tank problems with algae and cyano bacteria.
We always use & recommend some form of phosphate control in our saltwater aquariums along with activated carbon.
