As they say in combat - tactics may win battles, but logistics wins the war.From where the picture is taken (behind blue the chairs), is the entry to the room. I will have to start planning for the logistics for sure. I'm already using those cabinets that you see on the back wall right now for equipment. I have my RO container, dosers, and calcium reactor (plus co2) in the cabinet on the left and have a half dozen 1/4" RO lines running to/from the sump and the cabinet.
For the new build, I could do equipment on the wall where the 5ft tank is now. I'm sure the wife will want to put some sort of furniture there once the tank is gone and I could do something similar for the low hanging filtration/supplementation.
I am going to try and improve on my water change system with the new tank, so I'll add that to the list.
Something I semi-planned for with an adjacent room that could eventually be tied-in for my fish if needed.
