Plant not growing well

Hey williamng,

For the glosso/hc, were they purchased in its emersed form? It could be that they are changing its form from emersed to submersed state.

Also, are you sure your ph/kh test kits are working fine? pH of 7 & kH of 2 would equate to a mere measurement of 6PPM of CO2. Maybe what you can do is this, throw in some fast growing plants to stabilise your tank, then after which, start planting your glosso/hc.
