Greg Robertson Posted December 9, 2022 Share Posted December 9, 2022 Hi Everyone, I am rebuilding my 72 bowfront, I wanted a black substrate for what wil be a planted tank. I ordered 3 10L bags of Ultum Nature Systems Controsoil. Sadly once in the aquarium it was no even close to Black, It's a rather ugly brown. Any ideas about placing a top layer of something b;ack over the top of it? Link to comment Share on other sites More sharing options...
