Help with nitrate removal!!!!!

Ok, 150g Niger trigger, orbiculate bat, honeycomb grouper, black edge Moray, yellow tang. I feed 3 shrimp and a few pinches of pellets and about 2 square inches of homemade food in total a week. Reef octopus nw200 protein skimmer rated 250g, ATS, Water changes 20% weekly.i just replaced Rodi filters because they were old, and I think I was pretty much using tap. I love DIY projects, and was wondering if there were any really easy ways to reduce nitrates with house materials. I was thinking I could make a denitrator coil without the PVC, so like 100' coiled tubing, siphon fed. Would that help? Or do you need it in PVC? Any other DIY?

Sorry, and I have caulerpa. Lol. I just started vinegar dosing but I did vodka before and it made no noticeable difference. Hopefully vinegar will do the trick. Any other ideas??? Things laying around the house would be great . Any ideas welcome.

Tank is like 1.5 years old.... They're at 80-160... Ridiculous I know. Corals and fish are fine thank god. I did switch my sand out 2-3o this ago, could it be because my sandbed didn't establish????

Imo i would think that would be your cause the sandbed trappes the nutrients when disturbed it will release whatever nutrient it contains i made this mistake one time stirred my established sand and nitrates were out the roof i also got cyano as a result now i use tongan nassarius snails to stir the sand a lil at a time but ya i bet thats it you run your fuge light 24/7 im assuming

bigger more frequent water changes will help to get it down

Besides water changes- look into getting a denitrifier, a bigger Skmmier and maybe reducing bio load.

You could pretty much make a denitrifier out of a reactor btw. That's all they are. Slow drip and gravity fed.

Can't do a bigger skimmer. You mean a denitrifying coil correct? My only concern with that is since they run so slowly wouldn't the nitrate be made faster than it is consumed?

I have a denitrifier in my 220 reef. It holds calcium carbonate and sulfur (pure grainular elemental). It looks like a big reactor. It is gravity fed from the DT and then a slow drip (2 drips per second) from 6" above the sump to allow for oxygenation. The sulfur has the nitrate eating bacteria in it. You want a slower flow so that the water has a greater change of being absorbed. If you can't do a bigger skimmer- try adding another. You've got a few fish in there that are nitrate factories themselves.

Lol I know my fish are pigs . I've heard really good things about the marinepure blocks acting as denitrifyers..... If you place them in a slow flow spot apparently the aerobic bacteria takes the oxygen out then once it gets to the center anaerobic bacteria thrive. I heard it dropped nitrates from 100 to 2 in a 4500 liter system with 3 blocks... Any experience? Should I get a block??
