Planning a new makeover with my betta tanks

Busy planning to use my one part of the bedroom just to set-up all me betta tanks. At the moment they are scarted between my living room and part of my bedroom. My buddy donated me a 4 partition 1.2m fish tank stand as he into breeding Angels. I received some good advice from Altum on how to set-up and effective system.

So I am putting pen to paper to draw various designs. Especially with the high electricity consumption.
