I bought Kent Marine Nitrate sponge (Amazon carries it, so would most fish stores). It's for fresh or saltwater. Buy a filter sock and put this stuff in your filter in a filter sock. It takes weeks to work, but it does! I used to do 50% water changes, and by the end of the week would have a nitrate reading at 10-15ppm. Now I only take out 5 gallons (it's a 43 gallon tank) each week, and my nitrates don't go about 5ppm. It's good stuff. The other thing I do every week is take out my Aquaclear filter, and rinse/squeeze out (in old tank water) all my filter media. I can't believe the gunk that comes out of the sponges. I use that water for house plants - they love it! Your tank is newer than mine, so you may not get as much from your sponges, but each week, rinsing out all your filter media (not replacing it) can help too. I feed my fish way more than I ever used to, and these 2 changes (product called "Kent Nitrate Sponge" and each week rinsing out my sponges has really helped me.
Oh I use my old tank water to water my tomatoes!!! great minds think alike :)
