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.

Great product that works

I have a small outdoor pond with frogs living in there. The water was dirty and smelly. I tried a few natural things without chemicals but nothing worked until I used this. Now after a couple of weeks I can see the bottom of the pond and the smell has gone.

Totally ineffective product that makes false claims.

This product just did not deliver what it promised i.e. a clean pond. It is totally ineffective and waste of money. All claims made for the product are false. Extremely unhappy and feel cheated of my money. Would never buy it ever again.
