Anaerobic Bacteria in Freshwater Aquariums?

How effective is it at reducing nitrates?

I am very interested in this as well, if this does work would be an bonus on top of adding lvl2 sterilization..

Hey guys I shoulda stated I have this cannister setup pulling already filtered water from my sump so I don't have any mechanical filtration in the cannister, I do 30% water changes every 3 days , after I hooked up the cannister nitrates dropped from 30ppm to 20ppm after a few weeks of the cannister building bio.

A 30% water change every 3 days, would greatly reduce the total nitrate. How do you know your canister is effective?
I have an ORP meter that gives realtime nitrate consentration in the discharge. My system will only work if add a carbon source, sugar. I would love to find a way that would work with organics already in the aquarium.

Because I was doing the 30% water changes every 3 days prior of the cannister install.

OK, thanks for clarification. I am guessing your tank has meat eating carnivores in it?
I have a hypothesis that, fish eating fish poop, waste leaves a suitable carbon source for anaerobic bacteria. I have a bunch of algae eating African cichilds. I have a very cold 75 gallon with carnivores, but it's been too cold for the anaerobic bacteria.

Yessir you're very correct, have rays, bichirs, tarpon. Temps fluctuates between 79.6 -81.2

The purigen will reduce the total nitrogen load. I have to add sugar, in order too reduce nitrates. I am curious if their might be different strains of anaerobic bacteria. That might work differently.
My anaerobic chamber also removes phosphate, and then sulfates if I am feeding it too much.
My main additive is silicate remover, phosguard.
My tank is also overload on the fish side.
30 gallon with a 20 gallon wet/dry bioballs.
My matrix media is in separate container and gets about 15 GPD flow through it. Completely anaerobic.

I had to get a RO unit. I am all freaked out now with the phosphates (nothing have worked). I got the cichlid buffer, lake salt, and cichlid trace from seachem to replenish the water again. I ran a phosphate test after adding the buffer since most buffers are phosphate-based and it was 0,0. I cannot stand my tank full of algae anymore. Just in case I will run a GFO reactor too.

I have 3, 2.5" creek chubs, they spend all day eating algae. My African cichilds eat quite a bit of algea also. I have green, browns and purple growing, any large solid spot might last 3 days before it gets mowed over.

What kind of media do you have in the canister filter?

Having a canister does "not" mean a lesser amount of water changes.
In fact because canister often go a long time without being cleaned, they produce more nitrate than frequently cleaned filters, so in order to reduce the excess nitrate, more water changes are needed . And more nitrate usually also means, more algae.
