rubble in chamber 2...

[Doglover_50]

...slight trick question. I have a 16 bowfront with bak pak skimmer that has 2 "chambers" before water returns to tank.

As long as it doesn't affect water flow, does anyone see a problem to me adding rubble to the return chamber for some added biological filtration? The thought just occurred to me...

Nope, no problems. People do it all the time in the back chambers of all in ones like nanocubes and aquapods.
