Are Bio Pellets Reactors Becoming Abandoned?

[tebstan]

I also recommend a good reactor made for pellets not just a gfo reactor, nextreef,vertex, octopus make good reactors

Did anyone here try the Bulk Reef Supply reactor? It's just a GFO reactor with a special cartridge inside. It gets mixed reviews. Hard to get the pellets moving without high flow through it, but that's not supposed to be good for the pellets either.

another thing is people use them and think they can use only a small amount as just a supplement, but I believe you need to go by directions and use the amount needed for you total system volume

Why is that? (And how much is that? .5 to 1 liter is quite a range)
