Rainstorm, that is exactly my problem.....I am not 100% sure if it is the previously spilled water or a leak. Although if it were leaking from the seals or the black frame the sides or the front/back would be wet, currently the water is only coming from under the tank. Currently the tank sits 30% full and no water seeping, If I fill it up to 55-60%, water will seap. I am thinking of filling it up and letting it sit. If water does not stop seeping tonight/tomorrow, I may have a leak.....hard to believe :shark:
