My bet is you've got some little critters coming out at night and filling their faces.For a few days since the thread got quite some unexpected response I have been thinking of ways to make the concept more visual to all understand the basics of a bacterial “rip clean”.
last night I set 2 experiments to try and demonstrate it visually.
experiment 1
Decomposition of a shrimp in a small vessel
• Duration 18 hours
• 5 grams defrosted cooked shrimp
• 100 ml tank water collected just after dosing reef actif
Results:
• Shrimp weigh 5 grams
• ammonia 0 ppm
• nitrite above 1 ppm
comments:
There was no weight loss, visually the shrimp still looked fresh, there was a cloudiness of the water in the vessel although ammonia was 0 ppm.
I was hoping to have an ammonia reading to illustrate this part of the test that would show the results of slow decomposition is ammonia. It seems that somehow the carbon source transformed all the ammonia to nitrite. It’s a small vessel and so many tings can go wrong I will hope that @Lasse could chime in as he’s the most versed person I know in bacteria knowledge.

Experiment 2
Decomposition of a shrimp in a reef tank
• Duration 18 hours
• 6 grams defrosted cooked shrimp
• 25 gallons reef tank (currently at full dose of actif)
results:
• shrimp weight 3 grams (lost 3 grams)
comments:
The shrimp was left on a corner of the system for 18 hours, today at the end of the experiment the shrimp had obvious signs of advanced decomposition (see pics and video) and it lost 3 grams in weight

the test only had a duration of 18 hours due to the advanced decomposition, if I were to leave it for longer I would be able to remove the shrimp from my system for observation.
Also note that this shrimp would be the equivalent to a small fish or around 4 to 6 cubes of frozen brine decomposing in a system
