ChemBob Posted January 17, 2021 Share Posted January 17, 2021 I am going to be setting up a 100 gallon stock tank as a pond this summer, and am planning on rainbow shiners in it. What substrate does everyone use in their outdoor tubs? Gravel or river rocks? Also, what underwater plants does everyone do? I'm thinking about a lily, and doing a couple of crypts in the shaded sections. Thoughts / suggestions on submerged plants? Link to comment Share on other sites More sharing options...
