Max % water Change
Okee..
Like the subject says... what is the safest percentage of water volume that can be changed at any one time for a tank?
Currently I do a 30% water change every week on my 20gal nano. So about 6 gals.
--------------
I am trying to get my Nitrates down because of a problem with previous water changes that were adding Nitrates to the tank.
What are my options?
TIA
