how bad it is to supply co2 in filter? (cerges reactor in filter)
i know its always recommended to dissolve co2 after filter and powerhead, but since i see lots of advantages in doing the oposit i ask this.
scenario 1: most cilyndric shaped external filters already are constructed same as cerges reactor. so we can just pump co2 in its upper chamber of filter. this is what i am doin for a week already. basically i have cerges reactor that takes up no space and does not restricts flow. disadvantage is i lower HP inside my filter, but does it really matters?
scenario 2: cerges, rex and so on reactors all work on same principle- water flows the oposite direction with respect to where co2 settles because of archimedes principle. this means that it makes sense to fit reactor on filter input tube, because that way you wont use any elbows at all. advantage will be no flow restriction. disadvantage: again lowered PH in filter
