Well... that coral was in a 55g tank in my basement. my tank then was probably the worst example of a saltwater tank u can imagine.. i was excited about it at first till i realized all the problems i had in my setup. I learned the hardway. all i had was a seaclone hang on the back skimmer(not all that great). No RO filtered water. No reliable lighting schedule(cuz i didn't use a timer). anyways...
I remember buying a lawnmower blenny and it dissapeared behind a rock and i never saw it again and thats when my tank went sour. Over feeding, dead fish, and tap-water brought in all the undesirable chemicals that caused every coral in my tank to shrink/hide/melt/disappear. I was lazy on the maintenance.
i decided to step it down and get a tank half the size of my 55. i believed it would be easier to manage. i got a jbj nano cube 28g with compact fluorecents. I got a warner marine hang on the back skimmer rated for 55g. Most importantly i got a reverse osmosis water filter. If your doing salt water tanks off of tap water its like your setting yourself up for future failure. The water evaporates, nitrates/phosphates/otherchemicals stay in and each freshwater evaporation replacement adds more of those chemicals. Also i placed the tank in a place i would see it everyday; in the living room. That was probably the best decision.
My practices for that tank included ...
12-9 light schedule on timer,
feed nickel sized chunk of frzn mysis to my3fish(clown, yellow wrasse, blue damsel) once a day.
Clean skimmer cup every day or two with toothbrush/empty cup out.
Bi-weekly 1/3rd volume waterchange with RO filtered water. And i would add Iodine, Coral Vite, and Alkalinity buffer a cap full of each after the water change and once a week and Purple Up at night just whenever i felt like it .. like a capfull everyother night.
in the picture above where it says "old tank" thats actually my 28g biocube it was in there for a year. Just recently i moved it into a 29g rectangle aquarium with 10g sump and DIY LED lighting. those biocubes are hard to work with and clean being that they have no sump and u have to special order the fluorescent bulb every 8 months or the intensity and color begins to die..
