A single canister is fine, just a bit more maintenance. Run your GFO in the bottom using sponges to separate the GAC and GFO (assuming you're running both.) Adjust the top sponge (above the carbon) to allow little room between the sponge and the GAC to limit tumbling. Adjust your flow so the surface of the GFO "dances" and you're done
Great advice!! You could also just bag the gac and put it in the sump.Now try breathing Jamie LOL
You don't need a big reactor since all it takes is about 1 gram or 1 tablespoon of GFO media per 10 gallons of system water. The TLF Phosban reactor is good for a 150-200 gallon system using something like a MJ400 powerhead. Canister filters have too much flow and will grind the media to dust since it is very soft. 60-80 GPH is a good flow.
Wonderful info and advise guys! You all have taught me much about GFO (I now know what GFO stands for) what it's used for, how much to use, what to use it in and all the benefits I'll glean from using it.
