Echinodorus tenellus -- any way to avoid black spot algae on these?
Thanks for your reply. I guess I am going to have to fertilize with nitrate.
I have been avoiding it, thinking it is better for the fish if I have lower
nitrate levels.
How did you begin fertilizing? Did you gradually build up to a certain level?
What level (of nitrate) do you aim for?
Thanks in advance.
