Denitrate

Has anyone ever used the above product to remove nitrate??
I use seachem purigen, it doesnt remove nitrate but does make my water crystal clear.

Denitrate - 67.6 oz. | Multi Purpose Media | Filter Media & Accessories | Aquarium - ThatPetPlace.com

I really need to know what everyones secret is - every time someoposts their water parameters on here they always say nitrate to be zero, personally i find this and impossible task to acheive

 

I've never used it, but, so far with the SeaChem products I have used, all worked great. If you decide to use this, test your water weekly to make sure you replace the media when the Nitrates start to go back up. I use SeaChem's CupriSorb and it works great

 

Hey! I use DeNitrate! Works great! However! You water flow should be around 50-60 gph! This is very important! The longer water/medium contact time the better! I'm using it in Eheim 2313 External filter that provides approx. 80 gph. I'm also using PhosGuard by Seachem! It works really well!

 

so do you find it does reduce your nitrate then??

 

Right'o! In my case it was approx. 15ppm / 75 gal tank) . The medium looks like extremely porous small rock beads (almost like volcanic rock) and it's covered with irreversible nitrate adsorbent. Once adsorbent gets saturated It works as a porous biologically active material. Therefore small water flow is a need. To be honest, I'm always very suspicious about all these miraculous media that reduce everything! However this works very well! I've got 7 fish, 4 soft corals and one huge long tentacle anemone. So far so good, nitrates 0.

 

just checked out my filter - it has a rate of 680 lph, the website recommends seachem matrix instead so im gonna give that a try! hopefully it will work!

 

oh yeh thanks for the advice!

 

I used the de*nitrate by Seachem also but it didnt do anything for me. I think/know it has to do with the flow rate(in my case). My gph is much higher than what they recommend.

 

There are two reasons why one should use small flow:
1. Contact time with medium = better performance.
2. Microbiological denitrification is an anaerobic process. Small water flow assures all excessive oxygen is consumed by aerobic fauna and oxygen free water is processed by denitrification bacteria. Coil denitrifactor is designed to satisfy this criterion.

 

whats NO3?
