Bio-pellets I quit you!

[Lampshade]

The KEY to all pellets is having substantial surface area for them and not going crazy on the tumbling. I myself now run about 5L of pellets in my DIY.

I'll agree with this, i had my pellets hooked up to a maxi 1200, and recently changed them over to a Tee off the main pump. I have less flow through there now, enough to keep them tumbling, but not flying around like the MJ was. This seems to work better, i also changed the outlet from my skimmer intake to my refugium at the same time, that may be the reason also, but my HA outbreak's stopped and is slowly getting under control now.
