Nitrate levels

[specopsteam]

Does anyone have any fresh ideas about how i can get my nitrate levels down. They are at 30 PPM in my 55 gal tank which has been stocked for about a month. I have tried 15% water changes, I have tried to reduce the amount of food that goes in the tank. I have Live rock in the tank about 30 pounds of it so far. Could this be what ive read about when it comes to canister filters? or is there some other cause? Im out of ideas on how to get this level down.:confused:


I dont feel like the pet store in town is giving me very good advise beause im having more problems with what they tell me and they are only cleared up by people like you helping me

How often do you clean your canister filter? If you have a sump, try throwing in some macroalgae such as chaeto. You should probably clean your canister filter out every two weeks. They tend to be nitrate factories. 30 pounds of live rock isn't that much for a 55 gallon tank. I'd probably try to get about 20 pounds more.

I have not cleaned my either of my two filters yet. the local pet store advised me not to this early in the game. I am new to the saltwater world so i dont have a sump or anthing like that just hang on the back wet/dry and a canister filter. What is the proper way to clean a canister filter? what do i clean and with what? there is no need to repleace any of the filters so soon correct

Anything that traps waste will cause Nitrate spikes if not cleaned regularly. I run poly pads in my sump to catch some of the larger partials that my skimmer will not take in and change them at least once a week or when they are noticeably brown.

I hate to say that your LFS may have stirred you completely the wrong way. Others can chime in if I am incorrect. Looking at your setup, the undergravel filter, canister filters and hob wet/dry could all be nitrate factories on our system. I would also add 30lbs more of live rocks.

Typically, in order to keep nitrates low, you need a protein skimmer to remove them before the waste becomes nitrates, but for those that escape, you need something to remove them and this is usually regular water changes and a refugium with macro algae or a denitrator.

You should clean out the canister filters weekly, by thoroughly rinsing the sponges in water leftover from your water changes, so the dirt is removed without killing the beneficial bacteria. I would personally get rid of the undergravel filter as you may have a 1/2" of waster under there that you cannot even get to to clean out. Again, others may chime in withtheir experience.

thats the feeling that i was getting because it all seemed to go agains what i have read on here and im paying for it now. I will be getting a 75 gal tank here shortly and i plan to drill that and use my current 55 gall as a refugium. Does anyone have suggestions on how to not make this same mistake again. I plan on getting rid of all my filtration systems and using LS and Bioballs along with rock and alge in the refugium does that seem like a workable plan?

Leave out the bioballs and it sounds workable. bioballs will act just as the canister, HOB, and UGF do, nitrate factory potential.

Google RC for nitrates (http://www.google.com/search?hl=en&rlz=1B3GGGL_enUS241US241&q=site%3Areefcentral.com+nitrate+OR+nitrates+OR+no3&btnG=Search)

How come no one browses or searches the threads anymore?

There are only 1640 (and rapidly counting) threads on this topic...

Give this (http://www.advancedaquarist.com/issues/august2003/chem.htm) a read, some of the options help for some and others do not, but it will give you an idea of what your up against and some of the options to combat it.

[CruzinKim]

No, no bioballs. When the detritus collects on the bioballs, it's very difficult to clean off, so another nitrate factory.

A few things, in a tank as new as yours a nitrate reading of 30 is not that bad. That being said, you should have more rock and if you want to run the canister filters, do so with the bio balls inside. Take the bio balls out of your wet dry. When you run a wet dry the way it was designed to run it is very efficient but as you found out you don't have enough rock to process all of the nitrate that the bio balls are producing. They will not be as efficient in your canister but they won't hurt as much either. The canister will basically be used as circulation.
The UG filter should not be run the way the instructions that came with it says of the way your LFS told you to run it. You need to run it backwards and as slow as you can with a filter like a sponge on the intake. Most powerheads are reversable.
If you will be keeping the UG filter in there and running it in reverse, you will occasionally need the canister filter to stir up the gravel and clean the gravel. If you keep the UG filter in there the way you have it, you are in for big problems.
Don't use that filter floss that came with your filters for anything except when you stir the gravel to clean it (every 3 or 4 months)
I hope you are using gravel with that UG and not sand.
If you decide to go without the UG filter and use sand, forget what I said about stiring it up. That is a different system.
You also need to do a lot of reading.
Good luck.

I agree, no bioballs or as we call them "nitrateballs!"

Cruzinkim, I`m going to chime in here. You are 100% right! I was wandering whan some one was going to read that this poor guy has a , Undergravel 1970 , canister 1980, wet-dry 1990. Specopsteam, take out avry thing but the rock! Get at list 30 lbs. moer. Go back to your lfs and put tham all behind bars!

[specopsteam]

And they told me it was state of the art! lol looks like i was steered in the wrong direction. What a nightmare now i have to rip it all apart and start over o well guess you have to learn one way or another

[Mavrk]

You don't mention substrate. Make sure you get sugar fine (oolitic) aragonite sand, NOT crushed coral.

[Mavrk]

Oh, and your bioload seems high for such a young tank.

Actually UG filters came out in the fiftees which is when I started using them. Come to think of it.... I still use one :lol:

about this sand, I read somewhere that you should use different layers of different sized sand so that you can max your biomedia everything from suguar fine up to something like 2mm sand i cant remeber the exact specs but is that true or should i stick just with sugar fine aragonite sand?

[seapug]

different sand grades are preferred by different creatures, but the conventional wisdom nowadays is to use sugar fine sand because crap tends to settle on top of it, not down inside of it like it does with coral gravel, which can cause the waste issues. In the meantime, clean your canister filter ASAP if you haven't already. You'll probably be shocked at the muck it will have accumulated.

nothing wrong with a UGF....(and in marine tanks RUGF).
I just stopped using mine.....

[specopsteam]

sugar fine (oolitic) aragonite sand

Anyone know any good places to buy this cheap and not get ripped off with sand from Toys R Us?
