Hi Friends, I have just the smallest beginnings of cyanobacteria in my tank. It has colonized three little pebbles of substrate in three different parts of my tanks. What can I do to nip it in the bud now so it doesn't take over. 35GAL Tall CO2 2 x 65w lights at 6700K on 8 hours a day in two sessions. Thanks Shango _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
