So I've joined the club as well, thanks to a very piggy puffer in my 220. I'm running 2 litres in a converted CA reactor.
It's got a screen of that plastic needle point stuff and 2 layers of Enkamat that seems to work pretty well and not plug up.
But how much flow do you need to tumble this stuff? There's an Eheim 1048 on it now that just barely wakes it up.

All of the Pellets should be churning and moving in the reactor, more flow the better. My pellets are turning and flowing around my reactor with heavy flow. Pellets that are just tumbling on the top is not enough flow.

I'm not sure. The mulm that gets released is fairly sizeable, unfortunately I don't have anything that eats large things right now - just some photosynthetic gorgonians for the most part.

However, some of the fish go nuts over it, in particular my lavender tang seems to love it.

I played with the flow so that there was just the slightest bit of tumbling. I actually thought at first it might be better not to have too much tumbling but it started to clump together, so now I think some slight tumbling throughout might be better. I'll try to take a video of it maybe.

I replaced the top foam of the reactor with a single layer of Enkamat. It seems to stop at least 99% of the escapees. If I didn't already have the Enkamat I would have sliced the foam in half like Kien did with his.

I can't really say. All I have are gorgonians and zoanthids in this tank (and clams). I have a pair of butterflies that were slowly turning the tank into a FOWLR so everything else got moved into my frag tank until I decide what to do with the butterflies.

I found it wouldn't tumble in the zeovit reactor but then I was agitating that thing manually. The wider diameter of the circle probably means it would need a step up in pump driving it to tumble it..

Looks like the pellets work great for reducing nutrients, and safer than carbon dosing. I'm wondering if there's any use for this in a system that already has low nutrients.

I know it produces bacteria that provides food for corals, but won't live rock be doing essentially the same thing? Bacteria-plankton should be sloughing off the rock in the same manner, it's just not as obvious.

Still on the fence... but this looks very interesting.

What are you guys using on the TLF reactors to get these thing tumbling? MJ1200?

I've just T'd off my Sump return. A Little Giant 4

I use a maxijet 900 on mine and they tumble. I did have to mod the sponges though (cut them down very thin like enkmat).

Absolutely there is use for these in an already low nutrient system, I can now feed more and more often resulting in even happier fatter fish. The beautiful part of the pellets is that they are only used up based on the amount of nutrients in the system to sustain the bacteria. If the nutrients are low the pellets will deplete very slowly and the bacteria populations will be smaller.

MJ1200 is what I am using and works perfectly.

Crap, I threw my foam out. It was nasty LOL.
Anyone have a little chunk of Enkmat?
