gfo

[mustang51js]

should i take the gfo out of my reactor, its the dual one from BRS, i have a 3 inch crocea, i was thinking on replacing it with carbon or leave it emty and use the gfo later if the phosphates start going up

i only run GFO when i see unwanted algae starting to grow but i know many people run it 24/7 as a precaution. so it's your choice, running carbon wont hurt either..........
