The filter media was a great suggestion. I've floated bio-balls in all of the tanks. That way once they are seeded i can sell some of those to help jump a cycle.
Also someone left the fill tube running on one of the sumps when they opened. I came in to find 27 dead fish. As all of the good water had drained out and was replaced with un chlorinated tap water. grr.
I'm working on my first fish order right now. about a 2/3rds have to be the typical sellers (feeders, guppys, mollys, swords etc) I plan on getting some rare/exotic to give for the last 2/3rds.
Yea i am holding off on the salt stuff for right now till i get the fresh straightened out. My next big thing is to change out all of the substrate for sand. and agronite for the chiclids.
I have a cool idea for an open reef display down the road. I'll be using this with lights mounted from the celling. I'll have a center mounted overflow, with a 20 gallon sump. I'll have coral piled up around the center overflow.
