Janitors recruited for the Job

I have grown third & fourth generation salt water mollies that came from CQuest in Porto Rico and they were huge & colorful.

Coiled pipe at 4’ deep would get you geothermal heating & cooling and extra volume not effected by athmosphere temperature will dampen temperature swings.

in my experiences with mariculture, unlite areas allow cryptic zone biochemistry to deal with DOC and thus a closed recirculating system. I could not get an operating permit from Texas agriculture department with an open recirculating system. Yes, I used operating expenses as a tax write-off with a registered LLC.

This is an outdoor farm in Miami, the catch is the have a salt water well.
I am not far from natural sea water, but pumping a drum , hauling it of home then pumping into house is no longer interesting to me. When I go fishing I load up some 5g jugs and back them in the garage on a jet ski.
Yea, for me it would just be a small setup, circulation pumps and a sun shade and hope for the best. I have thought about burying a couple hundred foot coils of 1” polyethylene around 4’ deep or as deep as I could dig, just sand here.
I have a 10g experiment with macro indoors, just finished the install this weekend. If it goes well, may move some outdoors on the porch under a skylight and go from there.
Just messing around, and yes indeed, investor money, would have a dedicated aquarium room on a large property with a pack of rescue dogs running free. I will settle for the 1600sq ft, 4 dogs and happy healthy family.

The initial idea for Jaubert Plenum was the Monaco State Aquarium which used a constant flow of makeup water from the Mediterranean Sea to replace 200,000G system every 2 days. When I was active military in Germany, in 1968 I visited the Casino at Monica. It was quite impressive and when I showed U.S. military ID; casino management issued me a complimentary sport jacket for dress code.

Nice, I have a FW outdoor pond, 100g, that I stock with mollies and mosquito fish from the lake to keep the mosquito at bay. Have tried grass shrimp and other fish but life expectancy isn’t long.
Used to stock with goldfish, every once in a while an Egret will come along and clean the fish out.

Jaubert Plenum, haven’t heard of that in a while. Could be a jeopardy question.

Just google Monaco State Aquarium, will look into it more, pretty impressive.

On another note from the rock pool thread. Do you have any experience with Halymenia? Wondering if tumbling is beneficial. I have it tumbling now so will see how it goes

Thanks for your knowledge, good stuff

I may have answered this earlier, but will expound on tumble culture of seaweed.

In the confines of a refugium, I feel tumbling any seaweed is too much effort for the results.

RAS, Recirculating Aquaculture Systems, is the mainstay for commercial cultivation of seaweed on land, and tumble culture uses the shape of container and fluid mechanics to set up a vertical loop current whose inertia is energy efficient.

Tumble culture dramatically increases photosynthetic activity across all surfaces of seaweed as it tumbles, thereby doubling PAR input to seaweed with no increase in lighting energy.

Because of the billowing sails of Halymenia, I found it difficult to tumble without clogging up screens requiring frequent maintenance. My commercial seaweed of choice was Gracilaria Hayi.

I probably missed the earlier answer.

I set up the tank and realized it was tumbling. Instead of purchasing a smaller powerhead, figured would give it a go as is.
Makes sense know why seaweed is tumbled, I did not know that was the reason. I do remember that Hayi was recommended to be tumbled. Tried growing that in the biocube and it ended up full of Xenia, mushrooms, bubble algae, bristle worms etc.. It seems that the Halymenia has a defense against hitch hikers as I did not have the same issues, in same tank.

I choose to use a “desirable” macro instead of chaetomorpha in a refugium. At this time I am not using a refugium on the display.

What is in the display tank? If your goal is nutrient export, then I would go with something differrent than a refugium. I use refugiums to grow live food for display tank.
Can you link the system? if you have an online journal, I can catch up. With less than 2 hours of daylight left, I will be out of pocket for a bit.

Display tank is 150g SPS dominant, skimmer, kalkwasser/vinegar ATO, and uv. Oh and I have 1/2 cup biopellets tumbling fed off return line, this go around. I like to keep it simple.

Ended up with dinoflagellates after resetting the tank. I used the sump as an algae scrubber detritus trap 24hr light cycle. Would scrape off the algae with a razor blade and shop vac it out when it got good and nasty. Lowered po4 with lanthanum and left light on, bottomed out nutrients . I never used a UV sterilizer before now or had Dino’s. Figure will keep it in on until bulb needs changing then re evaluate.

But yea, Refugium wasn’t for nutrient export, I am sure it helped a little. Would have to grow a lot of macro to be practical. Carbon dosing is easier. I used to grow blue Ochtodes and dragons breath in the sump. A local online vendor would come by every so often, clean out my frag tank and take half the macro. That was back before the bottom fell out of the hobby. I am getting back into it again as I drifted away for a while

I tumbled Gracilaria Hayi in a 55G mono culture tank using a vertical loop current with a rising air bubble curtain on left side of tank and Mag 12 power head on bottom right side of tank. Initially, aragonite substrate at 1” deep was evenly spread out but as seaweed dragged along on tank bottom, it piled up near air bubble curtain on left side of tank. I never added trace elements or buffer because during lights out when pH fell, aragonite became a passive buffering media.

A secondary advantage of seaweed dragging across aroggonite was preventing epilets from attaching to seaweed

I don’t have many pictures,
Here is the Halymenia on top of the Hayi in the old biocube. Would use the tank to hold a fish or something for observation, mostly nothing in it except some mushrooms, Xenia, and columbella snails. this is the 10g with some live rock, power head and diy led , 7 green, 5 red, 3 blue chips. See how the spectrum works out. I added more rock since the photo as it was leftover from another tank that is getting cleaned up.

I like the idea of the aragonite. I have some potassium and sodium nitrate, trisodium phosphate, iron, manganese but no strict regimen. Tried to put tumbling gif here but ended up top

Tumble when you wish to maximize cultivation. I aquascape with both ornamental & utilitarian macroalgae (seaweed). I really like Gracilaria Hayi for its display qualities of red & burgundy, depending on light intensity. In lower level light intensity; red macros tend to display maroon and with increasing intensity they display fire engine red. Under very intense light, some red macros display yellow/orange.

This 55G tank with double stand will be moved into dining room alcove in the next two weeks. During the move I will disassemble sandbed and install manufactures under gravel filter with modified reverse flow using a power head. The bottom 55G tank was disassembled and moved into outdoor service. Both of these 55G tanks were treated with quadrupled dose of flatworm exit.
