if your using an organic form of co2 make sure your keeping your photo period short like 5 hours thats a lot of light for such a small tank if you want a longer photo period faster growth with less issues i would suggest going to compressed if not, just keep the light sparse or you'll run into problems if you have a ton of light and only excel as your carbon source. Root tabs are okay for low maintenance plants if you keep the light on too long and run into algae issues like GSA its time to start dosing the dry stuff to keep phosphates and TE sufficient .... then the addiction begins
