Wow, I did not think it was this difficult. So, if I run GFO I should be ok as long as I cut the dose and monitor levels? I ask because I am having phosphate and algae issues. I procured a new reactor and need what would be my best combo to run in it for my issues. Is the Poly Filter still needed if I run true GFO?

My next ?'s are on the benefits of running straight Phosban or quality carbon. I am still reading up on those. Thanks Karin and Justin
