    First I suggest you retest to make sure your result is accurate. API test kits are notoriously inaccurate. Once result is confirmed start to do a series of water changes to get the value down. 20 or 30% at a time if possible. You may need to do two or even three changes over the course of a week or 10 days.

    After doing the water changes you need to address the possible causes...

    Look at inital water source. Move to RODI where possible. Look at soures of nitrate being generated, are you adding in too much food or have too many fish? It could also come from an accumulation of waste. So make sure you are cleaning out filter socks regularily, cleaning sand bed, and cleaning out sump.

    After addressing possible causes, you need to think about nitrate management. Take a good look at your mechanical and biological filtration and make sure it is adequate. Does the tank have enough flow to get the detritus suspended, is the skimmer turned in and size appropriately. Are you on top of your regular water changes and cleaning..

    After mechanical look at your biological filtration. You have some macro algea so that should start growing and absorbing that undesirable nutrients. Just remember to harvest it regularily. Also you can give your biological filration a boost by adding in bacteria and additonal bio media if you don't already have (especially if you are running bare bottom tank). Carbon dosing and/or adding bio pellets, or even going down the zeovit route are other options to boost the beneficial biological filtration of you tank.

    Anyways, Good luck. Hope this helps get your nitrates in check.

    For start and recommended ...pH, ammonia, po4 and no2 & no3 and measure salinity lvl and temperature. If you keeping coral, then kh, cal and mg. If just fowlr and want to save money, just cycle longer like abt a month, spend money on dosing good bacteria and monitor salinity. Buy cheap leather Rock w pods... Once Yr pods multiple... Then can slowly start with good invert. Then slowly proceed to livestock. If you want to fast.. Then the test kits are important to test the parameter but do note of still possible new tank syndrome. All the best and welcome back.
