Green hair algae was my latest battle. So far it is in check. I have decreased the light with plastic binders mounted on the back and sides of the tank (since the room gets plenty of ambient light, even with the curtains drawn). The translucent blue binder as a background looks really nice! I've stopped dosing the microferts for a few weeks because of the high iron content. (It's a new tank with typical enriched substrate, so maybe applying ferts is not necessary yet?) And have begun dosing with Excel, which I believe has been the strong arm to defeat the green threads within a matter of a few days. It's still early in the game, hopefully everything will balance in a few months. Thanks for your kind comments!
