True, it's self cleaning!!

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. :biggrin:

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.

:razz:

nitrate
 

i built my own coil nitrate reactor a couple of years ago.it has clogged but i just blow it out.i'm planning on modding it so i can remove the top and change out the inner's every 6 months or so.my nitrates are 34 ppb on a hanna checker

nitrate
 

sorry .034 ppm.water change every sunday(10%)

So it looks like there are people that run denitrators and love them. With that said, there are lots of crack addicts too. Here is what they have to say:

Another option for nitrates seems to be mixing kalkwasser with vinegar rather than water when dosing for calcium and alkalinity. I am not sure if this would keep up on large demand systems, but it's interesting for sure.

Or you could use live rock and water changes :)
