So yesterday, I thought that there was too much evaportation, but filled my sump up as normal. I awoke this morning to find the sump once again low and this time noticed that it is leaking. The sump is made out of a 30 gallon long and it appears that the seal on the base of it is gone. Water is coming up from the bottom frame of the tank, and there are clearly no cracks. Is there an epoxy that I can use as a temporary solution, or as is more likely should I take today off and build a new sump.
