This is a pic of my 90g show tank, two weeks after I started it. ~01/06
Another pic of my 90g show tank, about 9 months later... 10/06
The only filtration this tank had was some chaeto running in the refugium and some filter floss that was changed out intermittently. I had a Mag Drive 9.5 return pump and a rio 900 behind the rock and a Koralia 2 or 3,... I can't remember,... in the right corner. I did water changes once every four to six months. Four foot T5 lighting, 8x54watt unit, no individual reflectors.
I wish I had a pic of it when it was two years old. My old computer crashed and I lost a bunch of photos. Coralline algae was growing everywhere, all the rocks had turned purple... it was awesome.
It sprung a leak in early 2008, and I had to move some corals to other tanks. It was never the same. I never resealed the tank - don't know what happened to it.
