![]() 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
