Mike, A few things to think about with the new room. I have been building/remodeling my hatchery for the past year and have wished at times that someone would have written down all the interesting things I have "discovered." Plan your water disposal system prior to your water delivery system. Cities flood because of poor drainage planning...the inbound plan was already in place. Plan for channels/chases between tank rows and in columns. You will want your room to be flexible over time...adding new electrical or plumbing runs is a pain in the neck through 4x4s in the wrong place. A work table is paramount...give up some tank space for a person space. My stereo is a critical need. I spend hours with the fish and the music helps. My heater is controlled by a wall mounted thermostat...the fan by another. Don't rely on the equipment internal controls...they are cheap and can fault easily. Leave a 1/4 inch (+) between the tanks. I place visual dividers between some tanks and the gap has made it much easier to remove tanks for cleaning. I am amazed at how often I use the workbench, the power tools, the torch, the bench vise... likewise, I thought with a temperature controlled room I would never need a tank heater...and so under wired the rooms. I am currently adding more plugs. If you really want to see your fish your choices of stand systems is limited to two rows (levels) of vertical racks or three rows in steps. That lower level just doesn't get the attention of the middle and upper levels. If you are planning a semi-commercial venture...the bottom space will more than likely become tanks...just beware that those tanks require the same care and the middle row (my favorite). Lighting is an issue that you should design for up front...it's coupled with that channel/chase idea earlier. I use ambient lighting from the ceiling fixture for most tanks. A sink is nice. I would like to have had hot water though. A refrigerator is nice. My microwave is valuable. The blower is great...it's the exhaust that makes most of the noise...I built a muffler. The air pipes should be designed along with the tank racks. Use radial electrical corners for better efficiency.
