Changing from gravel to substrate?
I set up my first tank with a gravel bottom, using Top Fin gravel. I tried putting in some (hortworth, not sure of correct name now, something similar to Brazilian Milfoil). But it seems to be dying off.
SO I was thinking of changing the gravel to a substrate and adding some low light. My question is this:
Is there a best way of changing gravel? Can I just mix in some substrate in with the gravel and it would provide enough nutrients for the plants? Or is the only way is to empty out the tank and start over?
I'd rather not start over, as my guppies are just starting to have fry. plus, I am not too fond of the cycling of the tanks, as I tend to loose a few fish always.
Any and all help appreciated.
