I run my own Aquarium maintenance and install company, been aqua culturing corals for wholesale and personal sales for probably 3-4 years and into fish tanks my whole life. Cut back recently and sorta redoing the one 200g bin I have left in garage.
Had some clams that size....damn milwuakee regulator on my Ca Reactor...now I have some HUGE ashtrays
I work at a local Fish/Reptile shop that has some great connections.
oh and HOLY Pocillipora and Birdsnest! nice setup, cant see if you have any or not, but some non photosynthetic corals under that SPS shadow would be SICK
