DIY UV Possible?
I'm having issues with recurring green water and am looking for a quick solution. I really want to get a UV unit, but cant part with the money. I got to thinking, and I was wondering if a UV LED would do the job? A 1 watt UV LED on superbrightleds.com runs about 6 bucks. Maybe I could rig up a PVC housing for it..
Is this possible? Thoughts and suggestions are welcome.
