ULNS - Denitrators

Aquattro · #1 03-14-2014, 11:59 PM

I have about 200g total water volume, maybe 100 pounds rock. I also run zeo part time. Meaning I forget to do anything with it for months at a time, which translates to "you can quit anytime you like".
I have never had measurable NO3 in 4 years. I attribute that to quality rock that I keep clean with lots of flow. I also have near 0 coralline on the rock, which IMO plugs up the pores reaching the anaerobic bacteria.
I change about 25% water volume bi-weekly and have never vacuumed my sand bed. Seems easy enough to me

You don't have to vacuum with sugar sand...

I had never heard of VSV dosing before. I'll look into it.

Reef Pilot, It's good to hear that some people run these types of reactors and haven't had stability issues. Funny enough, out of all of the options, the bio pellets worry me the most. BTW, I checked out your tank thread and it looks awesome! I hope to still be in the hobby in 10 years!

Anyone else have a denitrator of any kind?

VSV is also effective and good way to start before spending hundreds of dollars on the blue bottles.

Just to be clear, I inherited that 10+ year tank when we moved, so my time in the hobby has been since then.

Bio pellets work well, if you start slowly and use MB7 (to prevent cyano). Once the nitrates are down, the reactor is in maintain mode with very little bio pellet consumption. Like I said, have not had to add any pellets for more than a year. Was every few months the first year.
