![]() My tank has been running higher nitrates then I should have, between 20 to 50 depending on what light you look at it under. Here's my problem. My tap water is running at 20 after RO it is around 5. So after mixing it( Fluval Sea), it raises up to 10. It makes it very hard to lower nitrates when you are adding halve of what you have with a water change. Any suggestions would be wonderful. Thanks Larry

![]() You should be reading 0 after ro water. Maybe you need a new filter.

![]() have you tried getting a second opinion ? That does seem odd! I'd try another test kit or ask a Local Fish Store to test your water for you to see if they get the same result.

![]() No not yet just started checking everything cause I wasn't making any headway on my fight. Is there nitrates in salt mixes?

![]() That was always my assumption but with my test it showed an increase. Has anyone else ever tested new water for nitrates?
