There's something about an electrical solution that I just like.
But at ~$100, it's out of my price range, where a few dollars of chemicals would do.
So is there any way that we could build a unit ourselves?
The parameters should be as follows:
-it must be encased, to where the UV-C light can't get out. if it means using a 3/4" elbow at each end, that's fine.
-it should have a very low flow restriction.
-it could run on DC or AC.
-A 4 Watt source is apparently more than plenty.
Obviously the lightbulb would sit outside of a clear tube: would acrylic or glass be OK? I'm envisioning a build similar to my airtrap.
