Okay here it goes. Tank is 120 gal
71 x 17 x 22. 3 holes drilled in bottom one in each back corner and one in the back middle. It is currently coral sand and white real dead coral. I have to bleach the coral every month! I got this tank all set up with the fish. Some of them ar over 11 years old. The guy I bought it from has had it for 12 years. It has a 19.5 gal
sump with bio balls, bricks and filter material in it. A protein skimmer in the sump. a small RO
type filter and a large spa type filter. The over flow has a net to filter food and debri and a bio-filter then its filled with bio balls. I run the lights from 4:00pm until 9:00pm everyday. I have 2 24" 65 watt 50/50 bulb lights. I also have a large airpump that supplies several airstones for 4 walls of bubbles. It is set up on timers to shut the pumps off before the auto feeder dumps the freeze dried brine and planton every evening. I also have the tempature controlled by Medusa unit.
I do not test the tank. the fish have been healthy and I have not lost any.I hate bleaching the coral every month!! what would you guys suggest???
