I have a leak in my current old liner and have a new liner coming. My pond is about 500 gallons here in Cleveland, OH. I bought a 150 gallon stock tank to house the fish temporarily using the pond water. My question is that I have not had my waterfall running, so I currently have no biological filtration. When I replace the old liner, all of that beneficial bacteria will be gone with it. I was hoping not to have to cycle the pond once it is relined. When I remove the larger rocks that I have in the pond, I was going to put them in another container filled with pond water so I can hopefully use them to seed the relined pond with beneficial bacteria. Is this the best way? Any suggestions? Thank you!
