I am currently doing 10-15% water changes in all of my tanks every 3 days, I am thinking about doing 25% once a week because my schedule is cramped right now, which is better.
water change ?

That seems like a lot, I was told that more than 25% every week will not allow the tank to ever cycle properly, is this true?
I do this on all my tanks except my ray tank and my parameter's stay just about the same. My ph may jump .1+/- but other than that everything stays in good shape.beantickler;2597773; said:
i do 50% all the time. just don't clean your filters at the same time. i think 50% a week is best. in my fully stocked tanks i may go every 4 to 5 days
50% is only a good idea if you have a good source of bio filtration, otherwise, average is 25-30% weekly.
I have a big Pacu, and big Pacus poop A LOT, so lately, while the tank cycles, I've been doing a 40-50% water change every DAY. But, I think if you do 40-50% a week you should be perfectly fine.
50% is a bit much if you have 1 fish in a large tank with good filteration and a decent amount of substraight.
If you have a few fish in 1 tank with very little or NO gravel and really should have a better filter,? then 50% is recommended.

2x 15% WC is better than 1x 25%-30% a week. 50% WC is too much as it might change a lot of things to stress the fish such as PH, hurting BB colony=small cycle over and over causing ammonia and nitrite level to go up during every WC. FHs are hardy and can take it, but it's not as good for the fish.
I'd do 1x 30%-35% weekly if the schedule limits you, but 15-20% 2x per week would be perfect
