How long do UV sterilizer bulbs last?
5,000 to 9,000 hours
The germicidal UV-C lamps have a useful average life of 5,000 to 9,000 hours. Useful life means that during this time the lamp is operating at an optimal output level for neutralizing mold, fungus, bacteria and viruses. Inherently, fluorescent technologies like UV germicidal lights depreciate in output over time.
How many watts should a UV sterilizer be?
UV Sterilizer Selection Guide
| UV Bulb (Watts) | Maximum Flow Rate for Controlling: | Aquarium Size |
|---|---|---|
| 8 | 120 gph | under 75 gallons |
| 15 | 230 gph | 75 gallons |
| 18 | 300 gph | 100 gallons |
| 25 | 475 gph | 150 gallons |
How long should you run a UV sterilizer?
An aquarium UV steriliser should be switched on and running for 24 hours per day, every day. Exceptions would be setting the tank up before there are any fish in it, adding beneficial bacteria to the water, as UV light kills bacteria, or if you are using a medication that stipulates that UVs should be turned off.
How much does UV light cost?
Coil UV lights have a light cost ranging between $60-$285, an installation cost ranging between $100-$225, a lamp cost between $10-$60 and an energy cost between $15-$30.
What size UV light do I need?
Choose Between a Clarifier or Sterilizer As a rule of thumb, use 10W of UV light per 1000 gallons for ‘clarification’, and 30 watts of UV light per 1000 gallons for ‘sterilization’.
Does UV light use a lot of electricity?
UV LED blacklights, on the other hand, have improved efficiency values of 15-25%. For the same 100 Watts of electrical energy consumed, UV LEDs will emit 15-25W of useful UV light energy.
Does UV light hurt fish?
Ultraviolet light is beneficial to aquarium goldfish. The UV acts as a water sterilizer, killing bacteria and algae. Although generally beneficial, UV light can be harmful in doses that exceed the natural amount of light a wild fish would receive.
What size UV light do I need for a 75 gallon tank?
For a 75-gallon fish tank I would recommend going with a UV water filter that has at least 18 Watts of UltraViolet bulb power. This way you’ll keep parasites and harmful pathogens in check. A good recommendation that won’t break the bank would be the 18-Watt UV sterilizer made by Coralife.
