When we buy our next home it will have a unfinished basement. The reason for this is so I can build a room with the fish tanks in the walls. I am looking for people to say if they would ever do this again and the reasons. Also I have never had a saltwater tank. I don't know how big I will go. I am actually thinking of several small tanks hooked to one large one with the equipment hidden. So it would look like several pictures of a reef on the wall. The equipment tank would be hidden behind the wall. We have found that DH likes big fish and I like little. This way we can both have our fish. The large tank will be FOLWR and fake coral. The little tanks reefs. I hope that makes sense. Could I have all the tanks hooked to the same one? How large does the equipment tank need to be? I am looking for very honest answers regarding cost of maintenance also. I need to know how much daily, monthly,yearly these tanks cost once setup. I am planing on slowly getting all the equipment needed. And mostly second hand unless it flat out needs to be brand new. I can't justify tons of money a year on upkeep. I farm not much extra money for fish stuff. I am planing on using this as science lessons for our home school circle. Be neat to show these Iowa farm kids a piece of the ocean. We are slowly working on a 55gallon discus tank. I hope to be ready to get the discus before next winter. They are excited about this tank. So am I crazy or should I go for this if the upkeep is in my budget? I will be spending a ton time researching before I buy anything. I hope you don't mind me lurking around.
