Lighting and algae?

[asylumdown]

I didn't know Hanna had a nitrate checker. I'm lazy so if I could choose between a handheld checker and a test kit that relied on me matching a colour wheel I'd probably pick the hanna device lol.

I use the Red Sea nitrate test kit because it uses the same reagents as the Hach machine that I use at school (which really shouldn't go down the drain but there's not much you can do about that), but I'm gonna try and find me the hanna one now!
