lol i leave my community tank's light on all the time
I guess having 2 plecs in the one tank sorta counters the algae issue quite well, topped off by a few fish which like a little vegetation now and again
When I setup my new 190L tank which arrives on wednesday should I keep the light on all the time, off all the time or partially off and partially on

? The setup will be for malawi cichlids with coral sand & plenty of tufa rock.
