    Nitrates -Thoughts please?

    Folks-

    Here is my chem:

    FC: 3.5
    CC: .5
    TC: 4.0
    Temp: 81
    pH: 7.4
    Hardness: 390
    TA: 80
    CYA: 50


    I took a sample to the local Anthony & Sylvan simply because they have a means to test for borates, and I do not. I've been considering adding borates after I have read the accolades here but I wanted to know where I was starting from... -103lbs of Borax 20 Mule?? and 6 gallons of acid for 50ppm?? -Seems a lot, but I'll attend to that later...

    I have the TFP test kit (which gave me the results above). They did an entire battery on their Waterlink system which I found interesting (results blow) -and the results were similar enough to mine -I was not concerned. Except....

    Their system spit out a recommendation that because I have a "Nitrate level of 37ppm", I should drain and replace 61% of my water. I have never tracked Nitrates, much less thought of replacing water because of them. Should I be taking this recommendation seriously?

    Thoughts appreciated.


    Their Waterlink results -if you care to compare -again they were pretty close...:

    FC: 3.52
    CC: .29
    TC: 3.81
    Temp: 65F
    pH: 7.5
    Hardness: 403
    TA: 82
    CYA: 66
    Copper: 0
    Iron: 0
    Borate: 0
    Nitrate: 37

    Thanks for your thoughts.

    Nope. Nitrates and phosphates do not matter if you maintain the appropriate FC level (for your cya level).

    My thought is that Leslie's found out you had nicely balanced water so they want you to get rid of some it. That way you will need some more chlorine and acid, etc. to re-balance.
