I have never owned one, and the new tank I just got came with one. So I have a few questions:
JamesR the gentleman I bought the tank from said that the bulb was 3 months old. So I take that I am good on that. I have bugged him so much lately that I am going to bug you with it.
1)I have a small PH
pushing water through it. What is the rule of thumb for GPH
2)I assume that the little clear bubble at the end of it is for seeing if the light is on. I have it plugged up, but there is no light coming from it. Does this mean it's not working?
3)Who manufactures this UVS? There are no names on it but the name of the store it was bought at. Here is a pick of it.
