Has anyone build a DIY UV light? I need to build one for a 1,8m tank for fish. Please help
I bought a 40W GE Germicidal lamp (T8 tube). The 38W ballast doesn't seem to have enough power to run it. I have put on an very old 54W ballast. It is better but still doesn't do the job
you will need to cover the light so it CAN NOT shine into your eyes. it will burn your eyes and you will have arch eye, very painful
Germacidal light glows purple so you can see its on. We use them in our biltong cabinatesYou cannot see the UV, so how do you know that it is running "better" on one ballast than the other?

You dont need to see the amount of uv its giving off. Its designed to kill things! The purple glow is mearly an incication on where its on of off and not to be confused with antics.Yes, BUT you cannot see the amount of UV they emit, only the "Actinic" near-UV, so looking at one won't give any indication of how bright the UV emission is.

What is the best filtration to ensure perfect water condition constantly?

The whole purpose of this to kill bacteria and deseaces. I am currently struggeling with white spot on most of my fishs
I bought a ozone system without doing my homework properly.
