I have a reef octopus RO-PS-2000 int. Filled my aquarium up yesterday to check my overflow plumbing for leaks and tried skimmer then and it looked good. I was testing my aquarium with freshwater so i wouldn't waste my saltwater. Now that i have my saltwater in it as soon as i plug up my skimmer it completely fills with water. I have no additives in my water. I did epoxy some live rocks together. Could the epoxy do this and if so how can i fix it?
