It does not sure what's happening.

I thought it took a few months for the anerobic bb to start up ?

It does takes some time for denitrifying bacteria to grow inside media like Matrix or pumice stone. Use pumice or lava rock. Matrix, biohome, eheim substrate pro, others will work but cost more.

De*nitrite is doped with nitrate-absorbing chemicals which give the illusion that denitrifying bacteria are removing nitrate when, in most cases at least, they are not.

Ahh so we are hoping that by the time the dopping wears off the anerobic bb are multiplying ?

I assume but wouldn't expect to last too long.

These lights, are not doing any thing, noticeable.
25 ppm nitrate.

You can see the dark, and the light green. I will let it rest.


New aged and seeded screen. With a 150 watt grow light. Much more red than the 300 watt.

Would ceramic rings work? I found 6lb on Ebay for $12, so I could easily get enough to fill the five gallon bucket I plan to use as a canister.

The doping.

If anyone is looking at buying BioDigest it just went down in price. $30 for 30 vials on amazon, and $50 for 10 pro vials on Ebay.

I don't see why it shouldn't as long as flow is low. Unless the denitrate provides an environment different than ceramic rings because it is supposed tinge more porous.
