New reactor design for bio pellets reactor

[Reef Pilot]

I have a Vertex UF-20 with a Mag 5 pump (also run my chiller off the same pump), and it works beautifully. I ramped mine up gradually, but eventually had the full 1000 ml Vertex pellet bag in it, and it was tumbling nicely right to the top. I have been running it now for about 6 months and have never had any pellets clumping or clogging. What's important though, is not to use the sponge filters. Instead I used a mesh both top and bottom.
