Hi all, I will be enlarging my pond in a week. I bought a 50 gallon RubberMaid container and from the pet store an air pump and aerator strip. My pond builder is bringing two more smaller containers and aerators - I don't know what they are made of. Is rubber or plastic OK for the fish? I guess it should be since the pond is lined with plastic. I've got about 18 small and medium size goldfish and two larger koi (about 8+ inches) I've had my pond one year this month - so I've not done this before. Should I use the pond water and add a bit of well water to the container ? Any suggestions how best to care for the fish for the few days they need to be contained ? With thanks in NC - where it will most likely be in the 70s possibly even the 80s the week in question. Also - should I let the frogs fend for themselves or provide another container?
