There are some who use denitrators. Don't know if it's the same brand or not. Here's a link that might help you out. I was seriously thinking about getting one because I can't get my nitrates below 10, but, they cost $$$ and after the advice from many in this forum, 10 was not bad. Water changes should achieve what I need. https://forums.saltwaterfish.com/t/245812/lower-nitrates-w-clean-up-crew-aid
Looking forward to what you decide to do.
