The activated charcoal should be fine as long as it is not too old. You should change it every one-two morths or so I think. Make sure it has water forced through it for it to do its job.

If you are still using the bio-balls in the wet/dry I would take them out. YOu can replace them with LR rubble and cover them completely with water to create an anaerobic evnornment. I woul also cut back on the feedings. Feed once every two or three days. That could be a source fo the unwanted nitrates. Checkyou source water as well. I can not remember if you are using RO/DI water or not. The best thing I have found is adding more LR. In a 60 gal. you can have over 120lbs of LR for great bio-filtration. Good luck...Lando

Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian

I'd pull the charcoal / carbon out after 1 week, max. Maybe less. If you want to keep running it, that's fine - but don't leave the same bag in there too long.

just my 2c.

fwiw - I have 5 chromis, 1 lawnmower blenny, and 1 yellow tang. I'm running a EuroReef ES3-5, 160lbs LR, and 4" dsb.

I consider my tank to have a very low bio-load.

40lbs crushed size 0 and 1 argonite, plus 100lbs southdown/old castle sugar grade sand.

Agree with the earlier post about removing any filter floss. If you wish to keep it in there, thats probably ok, but I'd be rinsing it frequently.

Also not a bad idea to check your incoming water (before and after mixing) for N03... even if you are using RO, or buying it from somewhere you never really know whats going into the tank unless you check it.

I've heard of many people getting NNR without a bed as deep as mine, I think 2" is enough, and even know some folks here locally who export nitrates with LR only, though you do need quite a bit of it.

Another thing that helps is the type of inverts in the tank. Xenia can actually export some N03 as well.
