What is the difference with the 9watt and the 24 watt bulb for the green killing machine? Not sure which one to get
Answer by ChewyJan 30, 2022
​​​​​​The 9 watt and 24 watt Green Killing Machines are different systems. Each has its own special pump, light bulb and transformer. We recommend the 9 watt system for tanks up to 50 gallons and the 24 watt system for tanks up to 120 gallons.

will this 9 watt work for a 40 gallon tank?
Answer by ChewySep 04, 2022
This replacement bulb is intended to be used with the "AA 9 Watt Green Killing Machine" which is suitable for tanks up to 50 gallons.

Defective Bulb - Lasted less only 30 days

Purchased 1/8/2023 and notices the bulb was burned out withing 30 days - the green light on the transformer box was out. Not sure of any warranty as disposed of the box.

The Product

It arrived next day by 3PM for free shipping and was saftey packed to prevent damage as I constantly read reviews here that they don't work but this one does and you can not see the UV bulb on bit the green light is on so it is working and it keeps the water crystal clear.

Bulbs are defective

I have purchased many of these green killing machines throughout the years and they do work. I'm working on my second one now from chewy and believe me they are more then helpful when something doesn't work. This machine takes 6 full days to show proof of working and it will kill all green and mold in the tank. For some reason some of the bulbs just don't work. I believe it's packaging and handling

Exact replacement bulb.

This was an exact replacement part and my algae growth green water was cleared up by the third day in my 36 gallon fresh water tank.
