What Rock Is Safe For Ponds with Fish In Them

What Rock Is Safe For Ponds with Fish In Them

As a general rule avoid limestone and Cotswold. When water runs off these materials they can effect your water quality. Good practise is always to wash rocks, boulders and cobbles before putting them near a pond – if they were quarried in the rain they can be carrying mud etc on them.

When buying pre-bagged cobbles and pebbles, some of them are marked as fish friendly but we still recommend that you wash them before being put down near a pond with fish.
