convicts are central american, not african. . . .
as far as the plants in the refugium - even if you successfully keep plants in there and they use your nitrates, you will still have to do weekly water changes and substrate cleanings in order to keep the water conditions safe for the fish. don't expect to add plants and then never have to do any other maintenance.
duh! i wasn't expecting not to do maintenance. just asking if anyone else has a similar setup and how its working for them. i do daily maintenance to all my tanks!
