Teresa,
I have 2 tanks:
1. 210 Display - Mixed Primarily SPS. Filtration is: Biopellets, Protein Skimmer, Carbon
Lighting ATI Power Module which has T5 and LED. Other dosing pumps, Apex, UV Sterolizer
2. 100 Display - Lighting: ATI Sunpower - Just T5 lights. Same setup otherwise.
Both tanks are about 1 1/2 years.
