Thank you Corailline. Corals are all looking great nothing browning on me yet. I have some small spots on rocks that are turning brown (end of an eraser at most size) other than that no algae growth to speak of. I'm trying very hard to follow y'alls lead in just letting the tank tell me when something isn't working. yes I check and yes I panic and yes I want to buy something to fix it all but I'm holding myself back and just posting my results here. Listening and learning from all you great gurus.
