Agree wholeheartedly !
And there are several other very good reasons to do so, no to mention the ultimate safety of the method, as far as your fish stock is concerned.
And btw, for those anti-fishless cycling, old tank water in & by itself will do absolutely nothing to assist in building a bio-filtration colony. Old tank water has insignificant, or NO, bb in it at all.
Did I suggest putting fish in without good frequent water changes?
Hows about after the FC is done?
Then what? No water changes?
Water changes are easy and a good ethic to have regarding fish and their health, and it's a darn good idea to have new folks in PLANTED tanks to do this for the first 1-2 months, ADA, myself, many others strongly suggest this.
Old dirty tank water works dandy, ultra clean water, maybe not.......dirty filter water is perfect however. It adds PRECISELY water is missing from a mature established filter.
It does not get any faster and better than that.
Plant roots are covered with bacteria as well, and the plants directly remove and sequester NH4 waste from fish=> the silent cycle.
You pro fishless cycling folks do realize that this is a planted forum correct???? Water changes, zeolite, there are many simple solutions that do not require test kits or NH3. Nor that take 1-2 months (That alone makes the suggestion much easier and faster).
Who likes to test NH3, NO2 and NO3?
Anyone get into the hobby to do that?
