What chiller, size tank, sump size, and return pump are you using?

My flame angel thinks he's a Tang LOL. He picks at the filamentous algeas on my LR all day long, and any new fish that is added he tries to bully as a tang would. He even does this little "tail swipe" at the new fish for about a day but never does much if any harm. I have 2 clams, and plenty of LPS/softies and he hasn't bothered a thing. One of my favorite fish.

I haven't used the TUNZE products yet, but my next SPS tank will have a closed loop and a stream with a controller. I used to have a 4x2x2 BB with an ampmaster3000 hooked up to 2 1" seaswirls with 1000gph for the sump return. The way I had the tank planned out was to have ALOT of flow in the upper and mid column of water. Unfortunately, I didn't think about the BB tank needs, and I ended up having to do more manual removal of detritus off the tank bottom. If I redid that tank again, I would have the closed loop returns ALL bounce off the bottom of the tank, and put a stream or 2 in the mid water column. The seaswirls were not as great as I had hoped.

They'll pester your snails to death. It will take some time but it will happen. It took me about 3 months to eradicate them from my old system. I had to pull snails and scrub them in a separate container and discard the water. They also bothered my clams, even though they never got to proportions big enough to harm them, as I cleaned them about 2x a week. You definitely want to get rid of them if they're like the ones I had. Mine looked just like the ones you posted.

Careful! Those look like the dreaded pyramidellid snails. http://www.reefland.com/rho/2006/05/identify_rissoid_pyramidellid_snails.php

Nice tank BTW, I had one exactly like it.

With the open top like that and lumenarcs, 400 watters will be fine. Especially the way the tank is set up.

I have always had GREAT success with peppermints. I have never had a BAD peppermint either. IMO, the trick to get peppermints to eat them is to not feed the tank for at least a week after adding the pepps. It's an "aquired" taste. lol
