[Delphinus]

I have had several tank "whiteout blizzard" conditions as a result of pellets clogging. It is unsettling to see, but the tank inhabitants didn't seem to care (actually my fish seem to eat the "snowflakes"). My skimmer seems to pull it out and the water is clear within a couple hours. Also I have a filter sock - one thing since adding the pellets is I have to clean out my filter sock way more often, so I'm pretty sure it's pulling the stuff out too.

It seems to not take very long after the pellets have settled for the mulm to accumulate to "biblical plague of locusts" levels. Seems very important to make sure that lines, sponges and meshes aren't clogging up and finding the right combination of reactor, pump and/or reactor mods so that they are always churning.
