New reactor design for bio pellets reactor

[Reef Pilot]

I have never had mine clog, and never clean it. The only maintenance is to pour in more pellets when it gets low (about every 3 months).

If your reactor is tumbling properly, there is no mulm. All the bacteria stays with the pellets as they slowly dissolve. I've heard that tumbling too fast is not good either.

Also, I use MB7, which seeds the right bacteria for these pellets. And I have never had a cyano problem either, and I use the full 1000 ml bag for my 100 g tank. The trick, I think, is to ramp up slowly, and heavy use of MB7 initially.
