It's really hard to seperate the costs of the tanks. Beside the 15k and 52k I also have more than 100 others up and running. 60 of the smaller ones range from over 100 gallons to 800. So you can see how hard it is to say how much a particular one costs to run.
my first post says it best speechless just breathtaking you are a fish god myfriend put my local zoo to shame you prolly spend more a month on your tanks than i make in a year!!!!!
I have read you post numerous times reeling from the sheer commitment you have to the hobby. If you ever have the chance. i would love to see the rest of your tanks and setups. Oneday, I would love to get the Indianapolis crew together for a "Massive" road trip to come a see this tank.
