Lost some rock

[MitchM]

Looks good.

I do have one suggestion, though - It's something that I'm trying in my tank. I've plumbed a couple of supply lines in and under the rock piles to hopefully create an overall "outflow" of water from underneath.
I'm not too concerned about the direction of the nozzles, just that they're not blocked by any one rock.
From what I understand, the rocks are shedding a fair amount of junk.
I dunno, maybe you would want to try that next time you think of altering your plumbing.
