My nitrate levels are supper high. The best way to reduce would just be doing more frequent water changes?

Is there anythikng else I can do?

How high is super high? Doing a big water change along with more frequent water changes will help for now, but if you dont find out what is causing the nitrates to go up, you're gonna keep having the same problem over and over again. What kind of setup and filtration do you have? Are you overfeeding or adding something else on a regular basis that could be the culprit?

[Thatguy96]

I think I have over fed
not enough water changes
and over loaded my tank with fish ( a lot of tangs that crap like crazy!! Tang 7 inches)

[seaham358]

what type of water are you using? ro, ro/di and have you tested your top off water and new salt water for nitrates? Like Mikey says you need to track down the problem.

[MikeyZO]

How big is your tank? What kind/how many fish do you have? How often do you do water changes, and how much do you change at a time? And like Sea asked, what kind of water and salt do you use?

Kent Nitrate sponge cut down on the feeding and change that water!

[Thatguy96]

I cahnge the water every month, I have a 125
I do use RO DI (testig that would be a good IDEA!)

I just want to thank every one for all the responses!!

Natureef Denitrifier... I don't have that problem...

...the object is to reduce the levels to near zero in the shortest period of time as possible, with the least amount of water. On the other hand, if you reduce the level of water in the tank to 20% of normal and then refill the tank to a 40% level, you have already reduced your nitrate levels by half. If you then refill the tank to the 100% level, your nitrate levels will be 20% of the original level that you started out at. If, on the other hand, you reduce the 40% water level once more to 20% and then refill the tank, you will end up with a nitrate level of 10% of what you started with. Perform the 40% to 20% reduction once more, and you will end up with a nitrate level of 5% of what you started with. Just think about it for a minute. If you started out with a nitrate level of 100 ppm and used this method, your 100 ppm nitrates would be reduced, in a short period of time, to 5 ppm, which is considered, by most, to be an acceptable level even for corals.


basically what this aretilce is saying.. if you have problems with your nitrates do water changes like they say here (BIG water change) to instantly drop your nitrates. use RO/DI water.

You are better off doing smaller changes weekly than just once a month. I don't recall if you said how much you change but 10% a week wouild really help. Also a good skimmer and something to eat up nitrates like Chaeto.
Don't forget you have nitrates because you had nitrites. And you had nitrites because your critters are creating ammonia which gets converted to nitrites. So the more you get out of the system via a skimmer the less nitrates you end up with.
