Looking for ways to reduce nitrates

Please any recommendations on nitrates next to water changes. Also wondering about macro algae. What kind? Where to get? Can y put it straight into aquarium? Any information will be greatly appreciated.

You either remove them via water change, "feed" them to filter feeders such as feather dusters, sponges, clams, macro algae ect, or complete the nitrogen cycle with bacteria.

More live rock. Better flow (more powerheads). Less feeding. That's the basics. :-)

Check out the so Called "Algae scrubber " . some people using it with once a year water changing on their tank.

Bio-Pellets 100% work. Mine were in the 15-20 range, and in about 2-3 weeks of running pellets they are 0 . You will need a good skimmer to remove the waste but the pellets are super easy and cheap. I run mine in a Phosban 550 reactor with the bio pellet mesh screen mod run with a maxi jet 1200. You will need to start with about 1/3 of the recommended dose then watch you levels . You never have to change them out, just replace them as they deplete. Next Reef makes the SMR1 which would be great for this, and Bulk Reef Supply has a reactor for it as well. The dedicated bio pellet reactors are a bit more expensive, so the TLF phosban reactor or the BRS will probably be the cheapest route.
