50% Water Change Safe?

[Redbellypiranha]

I have a 180 gallon with two silver aros and a motoro stingray, will it be safe to do a 50% water change?

as long as your declorineating your water and have a large canister with a lot of biomax than youll be better off! Breeders do daily 90-100% water changes, bc the cleaner the water the healthier the fish. aslong as you don't kill your nitrifying bacteria than you'll be good

Guys I would also like to ask... since I do manual water changes with damn buckets... do I need to gravel EVERY week? or large water changes?

yes a 50% water change should be safe as long as the water you put back into the tank is the correct temperature. The water itself doesnt contain too much beneficial bacteria, so you can safely perform large water changes without having to worry. Some discus keepers do water changes (sometimes with automatic water change systems but it doesnt matter) that are equivelant to 100% water changes daily.

and about your second question... it depends on how often you are doing water changes

i do 80% water changes every week on all my tanks,have been for years and never had any ill effects.
As everyone stated as long as the new water is conditioned(temp,dechlorinated etc)then you wont have any problems

I do 30% WCs in most of my tanks every week but i do a 40% water changes weekly in my Oscars aquarium.

i do about 75% over the course of a week in my 150 gal but thats because my filter broke and im running filters that are too small for the tank
