Can Hemianthus callitrichoides be grown in a low tech tank without co2 and only flourish and excel(no shaded parts)? or should it be in a tank with 2.0wpg and co2 injection(would this require NKP and such?)?
Can be done either way. I have some growing fine in my low tech, Excel only tank. I like to dose NPK/trace even in non-CO2 tanks, although you can get away without it if you feed fish well.
