Discovered my 90 gal tank has a small pin hole leak on the RH side. Water has penetrated the joint about 3 to 4 inches in the seam. I do not have the resources to take the tank down and have it reseal at the moment. Can it be patched with aquarium grade silicone while on the stand? What are my chances I am looking at here? Has anyone had success doing this? Any tips to make sure it seals?
