We have a reverse osmosis water system but when we test our water for our fish it still shows high acidity. The nitrates seem to be high also. Is there something we can add to the tank to get rid of the high acid content? We have around a 50 gal tank with tetra fish in it. We have tried using the ph 7.0 but it doesn't seem to work and we have used it a couple of times. Any info. would be appreciated.
 
What is the pH now? Anything over 6.4 should be fine. As Dark Ryok mentioned, most tetras do best in acidic water.
