Good looking tank. Impressive on the Tunze wavemaker on a 30...would you recommend this device for a 90 gallon reef tank? I was thinking either a Tunze or creating a manifold for increased water movement and agitation...
And I do have some criticism here just to make you happy
I have had a 30 gallon reef tank before, and there is just no feasible way I see all those coral in there working out. If chemical interactions don't start to bother any coral, then surely you will be running out of room very very soon (but you said you had a 150, so actually these criticisms could very easily be non-issues).
There are a number of very large leather coral in there which slightly concern me in regards to new SPS you have put in there (again, chemical warefare is possible, but i'm no expert, trust me). Also, was wondering what supplementation you use (calcium, iodine, etc.). Also, not clear, is there a refugium on this tank or a sump (strictly 30 gallons or more volume)?
Are you planning on moving these coral into the 150 as they grow larger? Or will you be fragging a lot? I ask because your coral seem very healthy and soon will be rubbing up on each other (most notably that Galaxea, man!! 10 inch sweepers!).
Again, tho, the tank looks great. I too enjoy the 30 gallon model of tanks as I believe they are a great volume to work with (adequate volume, good random flow possible from powerheads, cheaper lighting, many etc.) and their only real drawbacks are, as with ANY tank, space constraints.
Keep us informed with pics. They look good.
