Update:
+ Added a Koralia nano and adjusted the other heads to try to get better all around flow -- will see how it goes
+ Params are still pretty stable at SG=1.024-1.025, NH3=0. NO2=0, NO3=15
+ Added 3 astrea snails -- don't plan to add any more inverts
+ Cleaner shrimp is doing well -- I had him give a hand-cleanin', which was kind of weird, but funny too

+ Removed the elbow return of the skimmer, so now the output flows out along the surface, which I'm hoping will eliminate the scum build-up I was getting in the sump
+ *Think* the coraline on the LR is spreading, but tough to say for sure
I've noticed a little bit of brown hairy growth on the LR -- is that algae of some kind? (I'll try to post a pic when I can)
As for the future, I'll do as suggested and hold off on any fish. I've been researching a lot about mandarins this week. I think I may start out my tank with a light, peaceful community stocking, and then down the road, once it's matured, get one.
Stay tuned for some pics!
