removing nitrates
 

Does any one have some good plans to remove Nitrates?

water changes.

:werd:

I wouldn't used crushed shells as a base/gravel (though many do).

I would NOT use tap water to compensate for evaporation or water changes. I would definitely suggest using at least RO water. RO/DI water is better because it will have ZERO TDS (Total Disolved Solids).

Assuming that you are not overfeeding and assuming that you are using RO or RO/DI water then doing some somewhat frequent water changes should solve the problem over a reasonable period of time.

I noticed the title of this post and am having same problem with chronic high nitrates. Water changes do nothing.

So you are assuming that Psideways uses RO/DI water, doesn't overfeed, does not use crushed shell, and is NOT using city tap water?

All of the above will cause a pepetual nitrate problem.

Yes enough water changes will help.
The solution to pollution is dilution..

However if they keep going up you have a larger problem. Overfeeding, or overstocked tank.

The best way to get rid of them with a better solution is a fuge with Cheato, Flow, and LOTS of lights.

Check out my nitrate results with a fuge added to my system..

I dont over feed and my tank is not over stocked. I have a constant persisting nitrate level that I cant resolve. I was wondering if any one had success with one of those nitrate removing filters?

Thank Guys

What water do you use?

How old is your tank?

assuming you stop whatever is causing your nitrates then water changes will work well but you have to do many of them, 10% around 15 times and you will see the levels drop. Personally I use a deep sand bed in a 5 gallon tank off to the side of my main tank and my nitrate is never above 1ppm. I've worked at a LFS and heard people say that De-Nitrate by Seachem works reasonably well.

Also...don't use canister filters or bioballs as they are nitrate sponges. If you have a sump then put your skimmer in the first compartment and that will remove organics before they can even break down.

Well, you could go with a remote deep sand bed for denitrification. Details are available using search function. Easy to build, pretty cheap too.

I run a sulfur reactor, I have a small tank, small stock but frequent feedings for them (my cardinals are pigs) and I had nitrate problems. Even with the remote deep sand bed, and weekly 21% water changes with RO/DI water, my nitrates were steady in that 10-30 range, and the sps did not appreciate that. Started running a Korralin bio-denitrator and it works wonderfully. I'm experimenting with building more (prilled sulfur is pretty cheap unless of course you buy it from korallin or another one of those marine companies) and so far it's pretty easy to build. There's some guy on ebay who builds them and then sells them for half the price of korallin but still a high price, and I kinda like getting to look into the reactor.

Of course, the purists would argue that I could get the same results by getting rid of all the fish! *grins*

This is the way that i have been getting rid of nitrates and Phosphates in my tank for the past 10 years....... i cant remember the last time i did a water change!! it has been years since i did one... i use a NatuReef Denitrification Reactor...
