I'm thinking about making a waterfall

I usualy recommend that if people want the chance to put in plants and fish but are not decided yet, that they use a biofalls set up to start the aquaculture with the beneficial bacteria and enzymes.

If you never put fish or plants and have the biofalls, you can always change your mind and add them later without harm to the plants or fish.

Some people like to put in the Water Hyacinths and Hardie lillies without fish. That is fine too.
