for. It's standard construction that will hold ~60lbs/square foot.
The pond, by my calculations, would be approximately 156lbs/sq foot (a
tank 6' long x 3' wide x 2.5' deep, which would hold 337 gallons. That
comes out to 2800 lbs total, over 18 sq ft., or 156 lbs/ sq ft.)
Can you get under the deck and reinforce it?
