Hello all, I'm moving and ordered a new 950 gallon tank. My current 1400g won't fit in the new house 
Last time I cut out the slab and poured more. Do I need to do that or not?
It will be 36 sqft and about 950 gallons. Will a standard 4" slab support that or should I cut it out and pour a deeper slab in that area?
thanks in advance!
