![]() Hi,
At $0.05 a kWh, 60W for pumps (24/7) - $2 a month. Overdrive T8 and HO or 170W for lamps (8 hours / per day) - $2 a month 150W heater (probably 4 hours a day) - $1 a month Food, about $2 a month. Salt and RO/DI...$8 a month. Other additives (Ca media, CO2, carbon) and test kits ...$5 month. So, that's about $20 a month for a fairly simple 90 Gal soft coral reef. Of course, that's just to keep the tank running. Add the cost of purchasing corals and other neat gizmos, and it can be an easy $100 a month habit. - Victor. |
