I'm pretty sure that is how Alfani is running his.

I have the water dripping into the refugium to oxygenate the water, but I still get the sulfur smell. If I speed up the drip, It doesn't eat up all the nitrates. Is there a better way to oxygenate the water? I'm sure there is, but I havent figured that one out yet. Maybe a camber with a air...

I've read through that one more than once. lol lots of good info in that thread. I understand it all, I'm just still trying to fine tune the drip rate. Too fast = nitrates in the output, too slow = rotten egg smell. I have found both of those extremes, just havent found the "just right" flow...

I agree with you Hawk, its very slow. Even on my small 75g, its VERY SLOWLY bringing down nitrates. I have read that you can use larger tubing, and a longer length in order to allow for a faster flow rate, which would in turn, turn over more water quicker. Or, just make 2 of them. Just my 2...

Alfani, if your still reading this post, I would like to here how yours is doing. Mine is designed pretty much the same way your is with a few slight differences. But all the stuff that matters is just like yours.

I used 4" x 24" for mine. Seems to be fine, but my tank is only 75G. I used 75' of 1/4" O.D. tubing(1/8 I.D., i think) coiled inside the pvc. I like the idea of having it on the outside of the PVC, because it leaves my room for bio balls in the center, and more room for the bacteria to do its...

My DIY coil denitrator is already dripping out 0 nitrates water. After only 5 days. Amazing!

Paul, I will keep dreaming that I have half the success you have. :) I have read a lot of your post on MR. sounds like you have quite a self sufficient(and long lived) tank. Maybe one day. lol Also, I like the idea of the bottles, they look pretty cool.

So, the DIY coil Denitrator has been running for only 5 days now. And to my extreme amazement, it has already cycled! Don't know how it cycled so fast, but the effluent water is reading between 0 and 5 PPM nitrates. The Tank water has very high nitrates, between 80 and 160(cant tell the...

Paul, Whats the theory behind the reverse UG filter. Is it that you are forcing the water to up through the sand and that's where the nitrates get eaten up?

I will post my results as time goes on. The CD has only been in service for a few days now, but I cant wait to see some results. Tired of high nitrates a frequent water changes.

Wow. 80 ppm down to 20 in 2 weeks. That's the fastest I heard of one of these working. I just built a DIY coil denitrator 2 days ago. I don't expect to get that good of results, not that fast anyway, but if I can get even close to 60 ppm nitrate reduction after a few weeks, I will be very very...

Alfana, how quickly did your nitrates drop in the tank water? Was it maybe 5ppm per week or something (after the cycle is complete)? Does your tank stay at 0 nitrates now? Or is there still a small amount of Nitrates even with the CD? Thanks again, Jeremy

1 drip per second, not per minute.

From what i've read. it appears that 1 drip per second is the recommended rate after the cycle process is complete. slower during the cycle process. Not sure what 1 drip per minute adds up to, but it seems really slow.
