Sorry, but I missed what brand pellet reactor you have? Mine is the Vertex UF-20 using a Mag 5 pump, but also running through my chiller. It has 3/4 diameter tubing, so can handle quite a bit of flow. It is tall, and takes a very small footprint, which I like, too.

I replaced (as recommended for bio pellets) the top and bottom foam screens with mesh. If I left the foam ones in place, for sure they would clog. When I fill it with 1000 ml pellets, it is tumbling about 2 inches below the top, but not high enough to stick to the mesh screen and clog.

I do wash the pellets in warm water and soak over night first before adding to the reactor. I started off very slowly, though, and took about a month or more, before I filled it up to the top. And I use that MB7 as mentioned before.

But, no, have never had them clog, and always tumbled nicely, even after a few power outages (up to 6 hours), they always started up fine. And I don't have any mulm anywhere, in my tank, or sump. I also feed the output of my reactor to the input of my skimmer.

My reactor plate holes at the top (and bottom sometimes) clogs with all sorts of sponges and other organisms that thrive in the reactor :sad: A thorough cleaning is just part of the maintenance schedule for me.

I use vertex pellets and Deltec fr 509 reactor with MJ 1200. I soak my pellets over night too. Maybe i should plump the outlet right into my skimmer and share the same skimmer feeding pump.

Gonna try that and see. Thanks for sharing your experience

That sounds like too much flow for the UF-20

Stop being so lazy and suck it up butter cup!

Not sure what kind of skimmer you have, but I have a needle wheel with air venturi input pump on mine, and would not want to mess with changing the input. I just have the outlet tubing from my reactor just close to my skimmer input. I think that is important, so the skimmer gets rid of any mulm.

I had a really dirty mature tank with very high nitrates and phosphates. It is amazing how clean it is now, algae all gone, and rocks nice and clean, and building coralline again on them. I am going to reset it in a couple months, but almost doesn't need it now after running this reactor. But I don't like my current sand bed, so am still going to do it.

My skimmer was also pulling a lot of really dark and very smelly skimmate, so it was doing its job, too.
