Hi, I was originally going to build my tank in the garage so that I could have a large tank but im wondering what the largest size tank I could have in my bedroom would be. The tank would be placed perpendicular to joists (45cm/18inches spacing) and both of the walls in the corner are load bearing. It is a bedroom and i'm in new zealand so the standard weight capacity for a bedroom is 1.5kpa or 150kg/m2. The house is a condo/townhouse built in 1989 and my bedroom is on the top floor of the house (4th floor) excluding the attic. The stand will be made of aluminium as it is light weight and the tank will not be deeper then 38cm/15inches because I like the shallow look and it also reduces pressure on singular points on the floor due to the weight being spread out more. Also the sump will be offset so that helps.
