Nitrates?

Nitrites. Many Nitrate tests will show both trites and trates. In a fully cycled tank, however, you do not have to worry about trites unless something is wrong.

my nitrates are at 20. Yesterday I did a 10 gal water change. My tank is a 75 gal.
This morning I did a 20 gal water change and nitrates still not down and this afternoon I did another 10 gal water change. Nothing has changed. Everything looks good in my tank.
Should I do another water change?

No more water changes, trates at 20 is not bad really, wait several days to do any more water changes!

Are you doing water changes with RO water? If your not.....you could just be putting more nitrates into your tank.

How much are you feeding your fish? They say that over-feeding will contribute to high nitrates also. My nitrates are at 40 right now and I can't seem to get them any lower.

There are many contributing factors that will increase nitrates.
What filtration are you using?
What is your bio-load?
How much food are you giving them?
The replacement water for both top off and salt water...what are the trates in them, and have you tested them?
Do you have a protein skimmer? A refugium?
let us know so we can pinpoint.
Sometimes, water changes alone will NEVER do it. You have to seek some other options, by answering the above.
As far as water changes, it is fine to do what you have, but now take a break. You do not want to remove all of the nessecary bacteria etc that contributes to the bio-process.
Also, you seemd to do a few water changes in rapid succession...are you mixing up your salt water for 24 hrs. +? very important to do this for ionic balance, wich in turn can affect the bio=process

Is this a fish only tank? If so, your nitrate levels are nothing to worry about.
These levels could be coming out of your tap water. Are you using RO? What kind of salt mix are you using? Mix some salt water and test it before you put it in the tank.
I live in the MD burbs of DC. I know i have nitrate levels of 20 or so straight from the tap. I know in DC there is some amonia in the water straight from the tap. A reverse osmosis unit takes these levels to undetectable numbers.

Depends. A water change cant hurt, but if you havent addressed the issues I put forth, and help diagnose, all the water changes in the world aren't going to combat high nitrates if you dont find the SOURCE of them.

I was wrong in feeding my tank I was trying to feed sun polyps and over fed the tank that is why my trates are so high. Never had the problem until I tryed to feed my sun polyps.

That is one definite factor...what about the other q's I posed? Filtration, powerheads (gallons per minute of flow) , etc...see a few posts back....

that's why you have to test for them
