b) I have not been using an air pump in the cycling tank until today. I learned from this site that increased oxygen might help with the brown algae. (When the goldfish are living in the tank I will of course have plenty of aeration from a 24″ bubble bar, bubble disk, and 2 air stones. I plan on learning about adding live plants in a few weeks, but am going with artificial for the time being.) Is there anything else I should do about the brown algae? Adding snails and other cleaner critters seems to be a somewhat controversial topic. c) I was planning on introducing each goldfish a week apart in order to give the system time to gradually acclimate to each increase in bio-load.
