i found some water puddles around my tank on the stand. they are dripping. I didn't notice this until i took my PC light of and now it's just the open tank. Could this be evaporation or a leak. I hope it's not a leak. i finally get my tank all perfect and ready to stock. I have waited 11 months for this moment. if it's a small leak can i fix it without getting a new tank. if it's small, what would happen if i just left it.
