thanks for the info. When i get around to actually building this monster, everything is going to be big. It will likely be in the 500-1000 gallon range, so the pipes are gonna be huge. Not worried about co2 since it wont be a planted tank, persay. Maybe some willow moss since its native to Ohio, but any other vegetation will be strictly riparian. The goal is to put a slice of central ohio streams right in the wall of my home. The best part is i get to catch all the fish.
It may seem a little far fetched but this is my dream tank and really my only hobby that costs me money besides fishin' lol. I love our native fish and love catching them. even if i cant keep them right now, snorkeling in rivers with nets all day is a blast and something i do every summer

Gonna be a long time before it can be achieved but when it does.... its gonna be EPIC.
