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?

[SIZE=-1]...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.[/SIZE] [SIZE=-1]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.[/SIZE]


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.

Hi

Can I ask a question, what are the nitrates doing to the tank. Were you having algae outbreaks? If not why not slowly cut back on your feedings and add a water change here and there. The only problem in a reef with too much nitrate is algae IMO

If you have a fuge with a sand bed for the cheato and little to no flow in there you will never get your Nitrates down. Or at least with any consistancy. I just dissasemble my fuge for the first time in a year. WoW! Bet a bed of Sh@#&%T. It was laying there and I have to say I bet it was causing me most if not all of my nutriant problems. I read it somewhrere on this forum that the top players not use a fuge. Now I know why.
I will take for reading tomorrow. but it almost dropped 50%. Nitrate from 80ppm to 40ppm. and phosphate when down 1 whole point. whetever. This hobby is tuff. Oh yeah, I will be putting back the cheato but with no sand bed and some rocks and a power head to move the water better. I will also lower the speed of the tube that runs down from my tank straight into the fuge
