rhunter513,
Good to hear AlgaeFix is helping you. One thing about the AlgaeFix is that it will not kill the spores. IMHO, this is why they recommend a weekly maintenance dose after the algae disappears. The weekly dose will kill any spores as they germinate into the vegetative stage. It could take a considerable period of time before the spores all germinate, once the algae appears to have all died off. Algae can multiply very quickly, even from a few spores.
