How to lower nitrates


My nitrates are at 20 and I can't seem to get them to go lower. They've been this way since I started the tank 5 months ago. I have a 29 gallon biocube with live sand and about 20 lbs. of live rock. I have been doing weekly water changes and feed my fish every other day. I also put a bag of seachem denitrate in the filtration.

Do you still have the bioballs and filter pads in the back of the tank? You need to remove all of that stuff and keep the sump area clean.

Filter pads only work when changed very often (every few days or even shorter periods) to prevent trapped food/detritus from being broken down by the constant water flow.

I would remove the Biocube filter. If you feel the need to, you put a piece of filter floss back there that you can easily clean or replace every few days.

Remove the Biocube filter and just go with the floss on top of the media basket. Clean or change it often.

How many fish and what type?
I have only 4 fish in my 40 gallon, including a fairy wrasse (which is a big eater and, therefore, a big producer in the nitrogen cycle). A couple of cleaner shrimp and some corals, and there is more than enough activity to look at.

The BioCube filter isn't a very good filter anyway so removing it won't be a big deal. I haven't used one in three years. I will sometimes put some floss back there if I've been messing with the tank and want to catch what I've stirred up, but most of the time nothing is required.

Regular water changes, feeding and stocking control, as well as a good protein skimmer do wonders on a BioCube.

any kind of filter pad or floss should be cleaned every other day.
do you vacum the sand bed?
what are you using for food?
