300 gallon "Outside Corner" Reef
Thank you for the nice words!
I use ro/di water exclusively. Have done that for the 25 years the reef has been running. I use the Triton method for the past few years. Before that I did massive water exchanges weekly. I now do a 5% water exchange once a month, but test for 30 different elements. IMO with proper filtration and adding the elements that get exhausted you can reduce water exchanges dramatically. In a 500+ gallon system that's a big savings. Not for everybody but it works for me.
Fish can live a long time. I get depressed when I hear somebody bragging about keeping a tang alive for 5 years, when I know it can live 4-5 times that long. I have two blue damsels that are originals that were added 25 years ago.
The real secret is consistency and perseverance. It's very difficult to keep the passion going for decades. But that is what it takes to build a stable artificial reef.
