Update! New light, but I'm having Spirogyra and BGA problems. I'm beating back the spirogyra, but the BGA is hard. I'm thinking of picking up some Bacter 100 for that. Apologies for the floating masses.
Looks great. Nuke the BGA for sure. I have successfully gotten rid of it without nuking it but it is more time and effort than it's worth. I have yet to try Bacter 100, though I want to, I just pick up some Erythromycin usually. People say deal with the root issue but in my experience, it is rare it comes back, even if nothing else changes.
