In my opinion their really is no 'BEST' method. Some tanks and plant respond better to certain methods.
No need to fix what isn't broken right?
1 had 3 tanks together with 1 light over them. The tank in the middle had BBA. All 3 were set up the same with nutrients dosed.
1 thing I have done, which was told is in her book, is have a siesta period (4hrs off)with my lights. This helps control algae for allows Co2 to build up.
Also you have to consider what plants you have. Some require a rich substrate. Also substrate peeters out in a year at the most.
It it works don't fix it.
