Hey Phurst, you should of shot me a message. There are a couple of tricks to getting them to cycle smoothly.

I'm glad to see this post come back to life. I've started selling denitrators and I've...

What is your drip rate? When they are cycling you often see a small spike in the nitrates on the effluent.

There is an easier way to start them, but it's smelly.

You'll see a drop in pH if any change.
It sounds like it's off to a good start!
I checked mine nitrates after this post came back to life and my reef is at 0 on the API kit.

I just use those cheesy blue ones from the LFS.
That is the toughest part. I have mine hooked to my manifold with a valve up stream then a valve on the effluent, made it much easier. eventually i...

Set it up yet? Half of Saturday is gone.......

:P

I started out at 1 drop / second, increasing the flow as the effluent hit 0. I'm not sure I'll every know if it reaches peak capacity. For the last 9 months or more I've maintained a steady flow...

You've gotta love the timing on that! <ack>
My DYI denitrator wouldn't lower my nitrates below 15ppm. Hope your build proves to be better!

Kewl system mongor!

Phurst, if you don't mind, post your tank and the effluent of the denitrator's nitrate level so we can watch the break in.

I've been running mine for over a year now. The...

Phurst, just noticed your signature. I had a buddy that was gluing coral to his rock in his 250 gallon reef tank. As he was leaning over the acrylic top he leaned onto the super glue container with...

Mongor, I'm not familiar with an auto water changing system. It has an alluring sound to it!
What is producing the grey sludge? I wouldn't think that uncirculated saltwater would create a grey...

Good luck Phurst. Mine was very easy to cycle, but I know some people that have had a difficult time getting theirs started. Once it's started it's carefree. Does yours have a aragonite chamber after...

I know this post is almost a year old and I'm curious to know how the denitrator is doing. I'm also curious to know if you would recommend them to others.

I've been running one for close to a year...
