    ADA vs Oliver Knott vs Colombo?

    Setting up new tank - 450L. Would like good substrate. Will be heavily planted, with fish. Appearance not too important, as like the black look of the final three. Have read all the posts and still uncertain. Cost is not the main issue. Have narrowed it down to ADA Amazonia 1 aquasoil, Oliver...
