Over the past 6 months I've been using BRS high capacity GFO, but I feel like its too fine grain for my media reactor(IM mid-size) and slows the flow down drastically. I switched to SeaChem Phosguard as it doesn't clog my reactors as badly, but I haven't noticed significant performance from either.
What are the pros and cons of each?
