Yeah I hear you on that one. After having a couple different tanks both fresh and saltwater I was thinking about doing a planted one but ferts are driving me nut so I think I might just bite the bullet and go back to saltwater before I get all this stuff for fresh and figure out I dont like it.
Did some more looking.
This I think is the cheapest fixture out there should be within specs and have about 5.4 wpg
If your handy with DIY type projects this should even be cheaper.
