nitrates high... sulphur denitrator

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.
 
Sulfur denitrators utilize sulfur media along with a calcium/limestone,etc.. media in a specific proportion or having a pure sulfur chamber exiting into a calcium chamber....

From the Deltec Manual..
Also the pH level can be very
low. It is therefore recommended to run the outlet into a container filled with a
limestone media as used in calcium reactors.
 
I just started running a sulphur denitrator. Sulfur media is hard to find; on this side of the pond at least. I think any media made for a calcium reactor will work. I’m using reborn because that what I have on hand.
