Hello,I don't know why these arent more popular. Took my consistent 20 ppms down to 0-1 ppm in a week. Sulfur pellets for $20 on Amazon. Standard BRS Reactor. Smallest pump you can find to run it, I'm talking like 1-2 drips per second. I promise this will take care of your problem as cheaply and effectively as possible.
Would you explain how to set it up? I have BRS reactor that I can use but not sure how to set it up for sulfur reactor . I have a sump and refugium with chaeto but still can’t bring my nitrates down.
