Hi everyone.

So I have struggled with high nitrates for a while and tried several things, water changes don't seem to do anything, NOPOX doesn't touch it and Bio pearls... nothing.

I have been lead down the path now of trying a sulphur denitrator.

I have been given a Deltec recirculating reactor (I think it was original a kalk one but should be able to do what I need) and I have bought some sulphur pears today.

My question is, what do I need to put above above it to bring the acidity back down that the sulfur causes? I believe hydrocarbonate but what is that also called and where can I get it? Is there anything else that can use? I was pointed in the direction of a product (aragonite) I believe but it was like £40 for a relative small tub?

Any advice welcome please.
Thanks.

Yup, and it takes a good 6+ weeks for it to be dialed in.

What have you tried?
I was in similar situation and getting algae reactor dialed in has been best solution.

Hi mate. I’ve tried cheato/other algae in refugium. Nopox. Water changes. Biopellets and nothing seemed to work. This may not either but it’s finding something that does I suppose.
The cheato seemed to work ok but now it’s kind of merged with some other leafy type of algae. Not sure what it is.

I had trouble with Chaeto until I started using chaetogro (brightwell). It’s still some work to keep the Chaeto going properly, but the chaetogro is worth trying!

Also just washing the Chaeto of other algae’s that will grow amongst it.
Best of luck

OP sounds like he’s U.K. based .... maybe easier to find the sulfur media.

no experience with sulfur denitrator. There is a great, long running thread on here called "Donovan's Nitrate Destroyer." It's a trickle flow, anaerobic setup.

I think the issue might be befor the export. U get nitrates from fish poop feeding decaying matter. I suggest to review feeding habits and perhaps using a turkey baster to blow off rock work. What are the nitrates you have? What is phosphates? If phosphates are off the nitrate is not balanced and will be harder to export/ for corals to metabolize.
