You can use a carbon source to do that if you feel comfortable with it and if yes I can guide you through it or you will find many info about it and how to do it (you will also find people that had problems with it, but if it is well done you should not have problems)

You can use biopellets in a reactor also for that purpose...

But before you do anything tells us a little about your experience as well as your present set-up.
Also if you use frozen foods, rinsing them with fresh RO water will help you to put less nitrates in the system.

The GFO will surely help :approve:
Now that's a very nice and well organized sump you've got there, however the refugium may need some "help" as it is still a "young" refugium and the caulerpa will remove mostly other components from the water and not drain more nitrates ... you could consider a algae scrubber ... it will not be dificult to put in your set up and will help the refugium to do its job ... have a look on what a friend over here made ...

THANK YOU ALL FOR THE COMPLIMENTS. I DO USE RO WATER AND I CHECK THE LEVELS ON THE RO WATER TO MAKE SURE THE RO UNIT IS FINE. I FEED 2 CUBES A DAY. I HAVE 2 PICASSO CLOWN, 1 YELLOW CORSET WRASSE, 1 SLEEPER GOBY, 1 BRISTAL TOOTH TANG, 1 Anthias,

I would try cutting back on feeding every other to every 3 days. And rinse to food. See if that helps before you go doing anything drastic. And make sure to keep yoursock clean so it doesn't build up to much waste in it.

How is the flow inside your tank. The nitrate can be caused by rotting debris that is just laying around. Also, check the expiration date on the test kits. Some LFS sells test kits that are years past their date because the make a habit of bulk ordering everytime Royal has a sale.

you seem to be doing everything right, not sure why your nitrate levels are high. The only other things that are left aside from too much food, would be if you didn't wash your filter socks enough. But judging how yours is so white, I doubt that is the case, By 10 gallon water changes, do you mean topping off included? Some people count adding water to their systems as part of their water change.
