Interesting, I never had any issues with Nerite poop. I find they do a much better job of keeping the glass clean than anything else I've kept. Which is extra important in the Edge because it's so hard to work in. It seems to me the shrimp do a better job of cleaning the hardscape and such of hair/turf/filament algae while the snails do a better job at GSA and biofilm.
I ordered a cobalt neotherm 25W from Amazon. I was using one of those 15W flat "betta" always on heaters under the substrate but it looked pretty well worn and I never liked the fact that it didn't shut off if the tank got up to temp. I would've had to buy a temp controller this time to be happy with it so I just spent a little more and got the neotherm.
I ordered some Marsilea, glosso, and baby leaf bolbitis from Bartohog last night. The bolbitis is to fill in one of the back corners as well as provide some more substantial cover for the CPD's and shrimp.
