i have a ocean free hydra 50 and hydra stream 3 laying around from my freshwater setup and i was wondering if anyone here was running them on their reef tank. i currently have an algae issue and it is advertised to remove phosphate too. i'm new to this hobby and i understand that it is very complicated with a lot of different elements. i just don't want to be doing more harm than good by adding them into my reef tank setup.
