I recently purchased an eel fro my 345L system and I want to prevent the spike of nitrate and phosphate due to the eel's food from creating an algae issue. My tank (which I bought second hand) had a Reef Octopus Biopellet reactor which I didn't use when setting up my tank, should I run it as a Biopellet reactor or use it as an algae reactor.
Thanks
