New pond: Can we use septic tank enzymes to remove moss, without harming the swans?
Date: 3 May 2014

We recently put in a pond for our pair of Black Swans and their one sibling. We had to rescue them from a golf course where the male was too aggressive.

The pond is about one month old and is growing moss, but the water is so green that you can't see through it.

I was told by the man that put in the pond to use the enzymes that are for septic tanks to clear it. He uses it on all his ponds and his fish are not harmed.

Can I use the enzymes without harming the Swans. The pond has a circulation system and a bog filter.
