Bottom 55G tank: This tank is less than 2 months mature. Everything in this tank was brought in from mature systems. It is the third stage of pest elimination before releasing curated rock to LFS.This is starting point of Dual 55G Skid tanks. Initially set up to process 200lbs of diver collected live rock & 50 lbs of live sand from Gulf Live Rock. The top 55G display is skimmerless, sumpless and fishless, with a powerful biochemical filter that uses a reverse flow thru 2” of aroggonite to perform powerful oxidation chemistry and the cryptic void in plenum is the habitat for the “sponge loop” that feeds detritus to the microbial loop and recycles POC back into the system as DIC which feeds photosynthesis that converts carbon dioxide into glucose.
In instrumentation, we call this ” a positive feedback loop”.
In Nature, we call this “Sustainable Maraculture”
PS: Top apex predators are Sally Lightfoot Crab and six Peppermint Shrimp.

Because this is a thread about bacteria and management of bacteria using diverse filter feeders specific enzymes, I will use liquid seaweed (inorganic carbon & little nitrogen) to favor growth for everyone and compliment that with phytoplankton as an organic carbon source.
There are no fish in this tank, I choose to favor amphipods & copepods as my gardeners, I can see them better than the bacteria. I also have much green macro algae and several red macros. Included in this tank are a variety of ornamental sponges, with my most recent joy two deep water NPS Gorgonions. The flame scallop is hiding and healthy.
I should note, that I occasional dose 5ml of ammonia when lights come on.
Note the last picture of muscle shell on sand bottom. Twenty four hours ago, I took live mussel from r

Note some pruning required on fast growing Caulerpa Paspoidies, This tank is nitrogen limited even though I have dosed 5ml of ammonia for 2 days in a row.

I should note, that I will up ammonia dose of 5ml to twice a day. Also, from the light green coloration of Caulerpa feathers, this system needs IRON. For that purpose I will add “liquid seaweed” at 1ml per 10G of system water.
PS: I dosed 5ml of ammonia and 5ml of liquid seaweed into both 55G tanks. There was (15 second delay) an immediate feeding response from NPS Gorgonion to this dosage combination.
PSS: I will attempt to use these three products to run my Caribbean mixed garden lagoon.
