Test results:

Ammonia (NH4+), soft cycle container: 1 mg/L

Ammonia (NH4+), staged cycle container: 1 mg/L

Ammonia (NH4+), classic cycle container: 1 mg/L

 

Nitrite (NO2-), soft cycle container: 2.5 mg/L

Nitrite (NO2-), staged cycle container: 10 mg/L

Nitrite (NO2-), classic cycle container: 10 mg/L

 

Nitrate (NO3-), soft cycle container: 5 mg/L

Nitrate (NO3-), staged cycle container: 20 mg/L

Nitrate (NO3-), classic cycle container: 20 mg/L

It appears to me that the soft cycle container has a slightly higher level of ammonia than the other two.

The ammonia level dropped in the staged and classic cycle containers. Plus, today was another water change day for the soft and staged cycle containers.

Are you going to test the bio load capacity of the containers once cycled? My theory would be that the soft cycled container could not sustain the same initial bioload that the other two could.

Interesting thought. I might just try that with maybe a weeks worth (35 pellets) of food, and see if one spikes more than the others.

Thanks for tagging along theplatypus!

The ammonia levels of the staged and classic cycle containers have dropped below 0.25 mg/L. Therefore, I will be using Seachem's ammonia test results for these two containers.

I'm running a few days behind you on my cycle, i'm on day 14 on my 10 gallon, non live rock and fresh sand. I'm at .25 ammo, 5+nitrite ppm, 15-20 nitrate ppm. No water changes on my tank either, i've been feeding the tank some MicroCrabs cyclop-eez pellets every few days.

Ammonia (NH4+), staged cycle container: 0.1 mg/L

Ammonia (NH4+), classic cycle container: 0.2 mg/L

 

Nitrite (NO2-), soft cycle container: 2.5 mg/L

Nitrite (NO2-), classic cycle container: 2.5 mg/L

 

Nitrate (NO3-), soft cycle container: 2 mg/L

Nitrate (NO3-), staged cycle container: 2 mg/L

Nitrate (NO3-), classic cycle container: 5 mg/L

 

The soft cycle container's ammonia level has dropped below 1 mg/L (but 1 mg/L was still the closest match).

it looks more like 0.5 to me
It does look like 0.5 mg/L in the picture, but it's how the light is shining through the sample (you can see the reflection in front of the test tubes due to the back lighting). In person, with the sample against the card, it matched closer to 1 than 0.5 mg/L (although it was slightly lighter than 1). The picture does show a good comparison between the containers. Shooting pictures in a light booth would have been a nice addition to the trial.

 

The next test should help confirm the drop in ammonia for the soft cycle container. Hopefully it will be a closer color match to the card.

The ammonia level for the soft cycle container was a fairly close match to 0.5 mg/L today.

Some newb is looking at this going wth did I get myself into.
Yeah, I'm a bit tired of running tests. Good thing we don't need to run 12 tests every day (6 ammonia, 3 nitrite, and 3 nitrate) when we are cycling our tanks. :)

 

Looks like a faster cycle this go around?
Maybe a little; I started the first trial on day 1 instead of day 0, so that affects the comparison. Temperature, or initial bacteria in the live sand might account for the rest. There are differences, but I'm feeling pretty good about the two trials supporting each other.

The ammonia level is now below 0.25 mg/L for all containers. Also, the soft and staged cycle containers got another water change today.

Thanks Mike!

Test results:

Ammonia (NH4+), soft cycle container: 0.15 mg/L

Ammonia (NH4+), staged cycle container: 0.1 mg/L

Ammonia (NH4+), classic cycle container: 0.05 mg/L

 

Nitrite (NO2-), soft cycle container: 1 mg/L

Nitrate (NO3-), soft cycle container: 2 mg/L

Nitrate (NO3-), staged cycle container: 2 mg/L

Nitrate (NO3-), classic cycle container: 5 mg/L

 

I'm impressed with the natural nitrate reduction of the DSBs (about 4.5" deep). Even without any water changes, the nitrate level of the classic cycle container's water is only 5 mg/L.

I appreciate that MGDMIRAGE!

Today was the 7th water change for the staged cycle and 13th for the soft cycle container.

WOW. this is some good stuff. Keep up the good work seabass!
Thanks nanoreefnate! I've decided to keep going until nitrite drops off too.

Sorry, no camera today. Also, nitrite now appears to be slightly lower in the the classic cycle container.

Plus, I'm on another bottle of Seachem nitrite/nitrate reagent (as I ran out again).
