water changer

right i had problems with my nitrate.. since iv got an ro unit and red sea salt so good stuff. tuesday night i almost emptied my tank (125litres) maybe 3 inch water in the bottom. i then today changed another 50 litres. when i change the water will all the good bacteria go to and will i have to wait a while to see any difference in my parameters or will it be instant. as iv tested about hour after the second change and its hardly moved

Do you know what is causing the nitrates? Overfeeding is on and the type of food are things that can make nitrates go up. Have you had anything die in your tank? The good bacteria is on the rocks and things in your tank as long as they aren't disturbed or out of water for long it will be ok.

Some dechlorinators will give a false reading if you take the reading less than 24 hours after using the dechlorinator.

what do you mean about dechlorinators mateand false readings

 

[LyndaB]

When you refill your tank, you use a dechlorinator. If you do a water reading sooner than 24 hours afterwards, you can get false readings. The dechlorinator affects the test.
