Anyone find a use for old VHO bulbs?
I'm starting to build a collection of them and I'm to cheap to throw them out.
could I use them on my FOLR tank and if so, wouldn't I need a VHO ballast ?
is there a low cost ballast out there (home depot?) that can handle one or two VHO bulbs?
Would old bulbs cause algae growth- or is the resaon for replacing only for coral growth.
