key requirements for good plant growth
Thanks to all for the excellent responses - I have set the CO2 bottle in
place and is bubbling away - new stronger lights have been ordered.
I suppose my only remaining puzzle is why a company like Juwel (my tank is a
Juwel Rio 240) include carbon impregnated pads in their filter systems if
they are detrimental to good plant growth and aquarium conditions generally?
