I have found someone who wants to sell their old 270 gallon tank. The tank has leaked and they have bought a new one. I have resealed several tanks with success in the past (75 g, 30 g, 125 g). This tank comes with a sump, stand and lights. The price is great. But I am concerned about the volume of water and pressure of a tank this size. The owner told me the tank leaked but it did not sound as if it gave away. Sounds like a slow leak to me. But the question is still the same. Even if the price is right is it worth it to role the dice and reseal this tank?
