I have 6 aquariums down stairs on the first floor of my house and would like to set up some more upstairs but I have never had a fully aquatic aquarium setup on the second floor that was more than 10 - 20 gallons but I want to get larger tanks and I don’t know how big I can go or rather I should build or buy the tank because if I buy the biggest I would go is a 75gl and if I build it will be at least 100gl? So I figured I needed to bounce the idea off you guys and see what would be the best choice ? Thank you!
