1) You don't NEED 1-1.5 lbs of LR
. It's simply the easy way out. If you want less or can't afford more then that's fine too. For some reason it continues to get spit out as fact instead of a recomendation. You need enough LR
to match your bioload (actually your intended bioload). In reality you don't NEED any at all. There are other filtration techniques to use in place. Or you can use SOME as a simple decoration item.
2) Call Marco and actually talk to them. You may be surprised. The new "Marco pre cycled" rock is different than their normal base rock. Call em and get the facts. Their use of the word 'cycled' has a unique meaning with their new rock.
