Happy to help! You'll have to let me know if you pick up an urchin! Do you have a build thread for me to follow?
Yeah, every interaction I've had with Kevin has been awesome. I was amazed that he seems to be handling all of the support emails himself...that's gotta be nuts with a startup, so bravo to him for doing that and doing it well. He seems like a really great guy, and I'm hoping his company is wildly successful too. It was a fun experience to be involved in from the crowdfunding phase.
Thankfully I haven't encountered any bacterial bloom issues yet. *knocks on wood* Hopefully it turns around quickly for you. Did you have the wild explosion of copepods in your tank? I had thousands and thousands of them for about a week until they died off to a sustainable number. The clowns had a field day picking them off the back glass all day.
If you decide to get snails I'd definitely recommend the trochus and nassarius that I have. The trochus snails do a good job with the glass, back wall, and rocks and can right themselves if they fall unlike astrea snails that you have to go in and flip over by hand if they land upside down (I'm not sure exactly how they've survived in the wild with that issue

). And the nassarius keep the sand turned by coming up like zombies when you feed the fish to pick up all the bits that sink to the bottom and then burying themselves again. Cool little snails. I could go either way with hermits...the zebras are cool to look at, but one of the plain hermits I have is a real ******* and bullies every other crab and snail in the tank.

Main plus with them is that they'll clean the algae off the sand which none of my other CuC members will do.
