How much do I need to put in a 5000 gallon fish pond? The new fish pond is used for the first time. thanks

Specific directions are stated on the bottle for start ups and maintenance. Do not over treat.

Is the container supposed to be sealed? I just recieved mine and there was no seal and powder was spilled inside the envelope

Yes, it should have a seal, but it occasionally gets stuck to the lid such that it comes off with the lid when you remove it.

Can i use this in a plastic dog pool?

Yes, you may use this in a plastic pool.

Can this pond-zyme sludge destroyer be used with a uv light sterilizer or will the uv light destroy the bacteria?

Yes, this product can be used with a UV light. A standard UV light used in filters for ponds will not destroy or inhibit the bacteria.
