Im just setting up a planted 6ft oscar tank and had an idea for substrate but am unsure if it will work.I want sand substrate but also lush plants,could i use shallow pots(4 to 5cm) filled with eco complete to pot them and then fit plastic mesh over the pots(like the stuff for java moss walls)securing it under lip of pot,small cuts in mesh to pull plants through then placing in tank in correct positions and filling tank with 6 to 7cm of sand,hey presto Oscar proof plants.The reason i want to do it this way rather than a layer of eco complete and then sand on top is i want the whole substrate sloping to back of tank and up to the sides,and dont want the dark eco complete exposed,any advice greatly apreciatted
