I am planing a reef tank but I have a couple concerns. I was looking at a glass 75 gallon tank but the probley is the only spot I have for it is the 2nd story of my house. The house was built in 1999 so do you think if I put it next a wall that goes straight threw to the bottom floor it would be ok? Also the house has a water softener, I was wondering if this would create a problem with carbonate hardness in the water or will it be ok? thank you for your time.
