Hi, guys I have a few corals in my aquarium.(Xenia, Zoo, Elegant coral, and anemones) Current nitrate level is around 10 ppm. Also, is this level of nitrate really dangerous for my corals and anemone? Also, I'm trying to reduce it with macro algae such as caulerpa in a 29 G refugium, and denitrate matrix rock in power filter. Can I just wait for low nitrate level without water change? Is water change is the only way to reduce it in a short time?

Thank you for reading.

Water changes are the ONLY way to lower nitrates, if your tank has reached its limit naturally.

Need a little (lot) more info to advise properly. For example are you using Live Rock? DSB? What Skimmer? Size of tank? etc

As general rules....if using live rock, make sure the structure is fairly open with good circulation in/around. When I had a substantial nitrate problem upping the circulationa around/through the rock was enough to sort it. Clean your skimmer regularly. Think about your feeding/maintainance regimens....is there a reason for the nitrates? What water are you using for top up/water changes.....have you checked that you are not putting nitrates into your tank?

There is no reason, with a bit of forethought, not to be able to manage the nitrates. Water changes can help, but don't get to the root of why the nitrates are there.

My tank is two month old 75 G with 29G refugium. Setup: 40 lb of LR, 50 lb of CaribSea dry rock, 80 lb of LS, RedSea Berlin classic protein skimmer with a Rio HF20 pump. live stock: a blue tang, a yellow tang, two percular clowns, four damsels Zoos, elegant coral, xenia, colt, star polyps, anemones. I think the biggest mistake for high nitrate was using tap water for cycling. After that, I've used RO water for water change. Nitrate level is maintained at 10 ppm over a month after I put macro algae in a refugium. I thought macro algae coulld solve a nitrate problem, but it couldn't until now. So, I'm wondering which one is better: water change frequently or wait for more time. Also, I use Nori to feed my yellow tang

Thanks.
