Well, I already have some chaeto and cleaner clams, and my nitrates don't seem to come down. I haven't had those things long, and the nitrates are only 10ppm, but still... do corals need nitrates to be 0? maybe a denitrator would be a good thing??

Everyone wants there trates to be zero.... You, yourself stated you haven't employed the other means very long. Changes should be made subtle, so you can honestly tell what is or isn't working. It's best to figure what is keeping your nitrates up. IMHO throwing mechanical gadgets at things really aren't the fix. What is your maintenance regimen? How often? Type of filtration? Feeding habits?
 
This is prob a dumb question but exactly is chaeto. And when you say cleaner clams what kind are they? I want a maxima clam they are so cool would that be considered a cleaner clam? Would a scallop be the same thing as a cleaner clam? My LFS has a couple of them

I did a 10% water change on Wed of this week. Prior to that, I'd done a 20% water change 1 week before that. I only feed every other day, but I only have a brittle star, 5 peppermint shrimp, hermits, and snails in my tank. So maybe that is still too much?
My plan today is to clean the inside of my protein skimmer, because it has algae growing on the inside, and then clean the inside of my Emperor 400 HOB filter. I have read that these can be a source of nitrates as well. I was thinking of rinsing off the bio wheels and the carbon inserts, and then finally the inside container. Then, I was going to do another water change to get them down. What percent water change should I do to get them down? I was thinking maybe close to a 50% just to get the process going???

Chaeto is a macro algae that looks green, wiry and tangled. The cleaner clams came from this site as part of a reef CuC package. I've read that they consume foods and other things in your tank that would lead to nitrates in your tank. I am not sure if other clams or scallops would do the same thing

great deal. as for needing a chiller. keep the lights hanging a little higher, place a fan blowing across the water.
was that a used system?
$200 is a smoking deal if it was new.

The ad said it was new! The unit does come with a fan, so I will see how much the temperature is affected, and then get another one if I need it!

Yes indeed a smoking deal.....IMHO the HOB filter won't cut it keeping your nitrates at "0". One thing we have to remember here is that all living things are putting off "waste" big, small whatever.....With that said, even with a sump utilizing filter socks we have to remember that the tank water is constantly running through the socks or being pulled through the filter media in a filter....There is were the problem lies....People who run filter socks and others will tell you that they must be changed frequently and do clog as well with HOB power filters....Are you running any media in the filter area? You must also remember the "clams" aren't and won't magically pull your numbers to "0" instantly.....It will take time and no method is foolproof.
Limiting the input of food will help some and you have to remember that carbon can be exhausted rather quickly...I would try to eliminate the the biowheel and anything that would actually harbor larger particles from being trapped or that isn't quite logical, I would try to pull my media out daily and rinse in RO water........

I'm looking into buying that same fixture. You'll have to let me know if it's very loud because that's my whole reason for getting a new one...and if I'm getting a new fixture, might as well go with metal halide right!

I do have carbon in my filters, and I changed them after a month. So you think I should rinse them daily? Should I try using a different media that is better? I did rinse the biowheels today. Although, they didn't seem to be growing anything on them like I thought. I am mixing about 12 gal of salt water overnight, and will do a water change with it tomorrow.
I was really hoping that the chaeto would help, but it doesn't seem to...at least not yet. I was thinking maybe I need to get the nitrates down to a low level FIRST, and then maybe it will make a difference. I will also cut down on feeding. Maybe just twice a week.
Is there something else that I can do?

I would rinse them daily......chaeto might help but with anything you have to be patient and changes should be made slow, so you can honestly see what is or isn't working....What test kit are you using to test your nitrates?

Ok I will do that. I did add the cleaner clams 2 weeks before I added the chaeto. It's only been about 2 weeks since I added the chaeto.
Today I did ~20% water change so that they don't get too high. I will test again tomorrow to see where I am.
I use the master kit from Red Sea to test my water. It has tests for ammonia, nitrites, nitrates, pH, and alkalinity. I bought a separate kit for phosphates too.
If I rinse the media in my filter once daily, can I do it in tap water if I get as much water out as possible before putting it back in? I used my RO water for the water change, and I'll have to make more water tomorrow to rinse them. Or maybe use treated tap water to get rid of the chlorine?

Try getting your hands on a Salifert or Seachem test kit....I'm not very fond of the RedSea test kits....I use to use them, but I found they weren't consistent enough for me.....You could use the water you drain off from your water change to rinse, swish your media in....trying to have as little if any die off of bacteria.......

Did you find that the Red Sea kits gave too high of levels, or just that they were inconsistent?
I will try rinsing my media daily and see if that helps!
Thanks so much for all your help!

Not very accurate when I ran multiple tests with different kits side by side. What kits do your LFS use? If possible you test and take a water sample into them to check your numbers.....

I was thinking of doing that just to check. Maybe I will do that this weekend. I'm not sure what they use. I can pick one up while I'm there if theirs works better.
