As some of you may already know i have been working on a new fish house for the last couple of months, of which the center piece of is going to be a 900 gallon (8x6x2.5 foot) tank which Windsor Aquatics are coming to build on the 20th of this month.Well a tank of this size and volume needs a substancial base to sit on so today i began laying the concrete block piers that will support the tank
