Tip: When inserting the new modded middle tube into the reactor chamber with biopellets inside already, shove it in, screw the lid back on, hold the reactor sideways, then take a rigid tube and poke down into the middle tube to clear out the pellets stuck inside. If you dont, then when you hook up the pump, it will be totally blocked and nothing will come out of the tube. Maybe even squirt some water into it to clear the blockage.

I pulled the knitting mesh out that was The top and now everything is going fast again. I will try the glue together mod later to try to dial back to the mj1200.

bottom piece removed and the other pieces glued together.

everything was flying around so much i had to tune it down to the 1200.

now to give it a few weeks to stabilize and perhaps put a bit more pellets in at some point.

Thanks, they're not totally off the list for the next build. I've got space in my future sump for the TLF 550 and an almost full bag of vertex biopellets, so there's a really solid chance they're on the menu. I would for sure have kept them running in my 90 if I hadn't needed to have broken it down.

I will hopefully have years of tweaking in the next tank ;)
