Bio pellets are peeling and clumpy

[ALang]

I find that if I don't dump out my pellets and scrub and rinse out the moded pads every month or so, the flow gets restricted and the tumbling slows down to next to nothing.
Then I'd gently rinse the pellets, and pour them back in, with the help of lots of water. Man, they are really "sticky" and hard to put back into the reactor.
I have mine now for 8 months and have no problems rinsing and using the RO (freshwater) to help pour them back in.
Then I just start the reactor back up, and SW will then swirl the RO water out of the chamber.
BTW, I run a TLF reactor. And I keep it at rapid boiling speed of tumble. HTH.
