Nitrate Issue

[brick-brothers]

Hey guys, so I have some nitrate issues that I thought I had under control. Im doing some water changes and I feel that I should do something else to bring it down. Right now I'm running TLF bio-pellets that I started a month ago. Is there something else I can do to help with the pellets running?
By the way, my take is sps dominant.

Look into carbon dosing

I was thinking about vodka dosing but not sure if it will crash with the pellets I'm running
