Carpet plants and pool filter sand
Has anyone had any success with carpet plants in pool filter sand, with water column dosing only?
Other substrates are simply too expensive here in Australia, since they all need to be shipped an extremely long distance.
Also, I thought I might try mineralised topsoil. My tank needs to be moved several times in its life (rental property) so I'm concerned that, when moving the tank, I'll stir up a god-awful mess. Pool filter sand, on the other hand, stays clean and is good for corydoras and kuhli loaches, as well as a few other fish I have inclined to burrowing.
With those things in mind, what's the better option?
