alright,my tub thing thats about 200 gal or so has more than half plants,6 1 to 2 inch comets and some misquito fish,and a laguna pump that makes like a little fountain on top of the water for movement and oxygen.THe water is pretty dark now,its been set up for a few weeks,I read that goldfish do good in the green water but honestly I can hardly see them now.I know this is a common issue,but I would like to do something about it,also wondering,is it really ok for the goldfish,I dont want them to die because of it.
