SPS Growth Puzzle

[Aquattro]

Jason, yes, I've taken small tips off of colonies and mounted them, nothing at all. I haven't dialed back the flow, but it's not crazy like I used to use, just 2 smaller streams (6060) and about 500gph from return line, maybe.
I might try that too though, and maybe then I could add sand -lol

Marie, thanks, had my own, had to treat a couple of months ago.
