I know there are a million high nitrate threads but...

I have not found a satisfactory answer to my question: is there an effective way to use seachem denitrate in a tank? I have a simple 55 gal and I can't use an external coil or filter. Can I put the denitrate in a bottle or container in my tank that would limit the oxygen? Is there a way to do this in a safe and low tech way? I'm doing the usual water changes and maintenance, I just need a little extra help to keep the nitrates low.

You can follow my design if you are interested.

You can try dosing vinegar too...worked for me

The SeaChem product doesn't need to be kept in a container. It functions as artificial live rock. It'll likely take a lot of media, from what the fish breeders would say.

or you could use seachem matrix instead. it's pretty much the same thing, but larger "rocks" so it doesn't require such a slow flow through rate.

This is some great info thanks!

I would just scrap that idea and dose a carbon source. Check out my thread I'm battling high nitrates as well and I dose Red Sea no3po4 x so far so good. If you want it to be low maintenance get a dosing pump and your good to go. For your tank a bottle would last a very long time.

not knowing if the OP is running a skimmer or not, dosing carbon may be counter productive.

Oh yea then in that case I wouldn't dose any carbon to the tank.

Organic carbon dosing ,though I prefer it for my main sytem , isn't necessarily the best or easiest option for every tank. I"ve used the seachem matrix pebbles in some cases even some with carbon dosing in play: it's very porous affording lot's of low flow areas for anaerobic NO3 reduction. The dientrate product is just smaller requiring some cantainment like a cansiter filter tray or mesh bag in an area with adequate flow.
