Health & Wellbeingwhen i was little my grandfather had a koi "patio pond" in a metal stock trough. I was wondering if it would be reasonable to do the same in a rubber one?what considerations would you consider?
Confirm it is made from a non toxic compound, such as polyethylene. Do not overstock it with fish. Provide adequate filtration and monitor water chemistry regularly. New ponds, just like new tanks, need to be properly cycled before fish are added.
