First the 75: bought used a few years ago, but I have made substantial changes since then (equipment as it stands now below).
Also, a FTS allowing you to see the "display" refugium on top (and the mess around the tank!).
Now, some close-ups (a little dated, but they have not changed much besides excellent growth).
And here's my favorite: a few months ago, my prize star polyps spawned in quite an amazing event.
Equipment:
Light: 440 W VHO on an IceCap 660. No metal halides, and I have plenty of light.
Skimmer: generic; not the best performer (my homemade one on the school's 140 is better, but it's really a high-performing skimmer) but it gets the job done.
Water movement: Quiet One 3000 on dual returns. Two oscillating powerheads.
Refugium: 10 gallon "display refugium" above the tank. Pump fed with a gravity return.
Care:
Feeding every day, one whole cube of frozen food
1 gallon special kalk mix (2 tsp. w/40 mL vinegar) added every morning
5 gallon water change weekly, along with skimmer cleaning and algae trimming on demand
Livestock:
Fish: 1 yellow tang
1 Foxface Rabbitfish
2 common clowns
1 pajama cardinal
1 decorated goby
1 flame angelfish
Corals (or sessile inverts):
1 very large colt
2 very large toadstools
4 or 5 smaller toadstools
1 blue brain
1 colony Galaxea
1 Scolymia
3 or 4 colonies of star polyps
1 colony of Pavona
2 croceas
1 Heliopora
2 large Sinularia
1 very large green brain
1 pagoda
1 gorgonian
2 green fuzzy mushrooms
1 Haddon's carpet anemone
1 Cynarina
And lots of other stuff I haven't counted in a long time!
