Christmas in a Macro Lagoon

I like bright & bold colors. Red & green are two of my favorite colors. I call the combo my Christmas theme.

Greens are supplied by Grape Caulerpa, GSP and Green Sinularia.

Reds are supplied by Red Grapes and Dragons Breath.

Don't you mean 'salad bar'? Kidding!

I agree, it's nice to have both green and red. I'm currently a bit low on greens and my reds just don't pop without them.

Green & Red Grapes

I like this Grape Caulerpa making shade for Red Grapes.

Note the pale look to the Red Grapes on diver collected Gulf live rock on the right. This is what Red Grapes look like when moved from dim to intense light. The cuttings on the left are a dark burgundy.

That's a good comparison. I'm still hoping my red grapes come back, in the dim end of my tank. I wonder if too bright light has been the reason I haven't had good luck with these plants.

For certain, with red grapes that is the case. I sometimes wonder if Red Grapes grow at >60’ depth to avoid competition. The reason I say this is because I recently have had an explosion of red grape sprigs everywhere, including high light area. Can red grapes photo adapt to different or more intense PAR, I don’t know. I have moved a bracket with red grape starts to a different place with more light. We shall see how it responds. Same light just a different place with more of the same light spectrum.

Thanks. I like your CheasPeak Bay biotheme.

4’ Chinese light bar with green, white and heavy blue for a 12,000 kelvin color. On all my tanks I add iron, iodine and vinegar as a carbon source. No skimming.

On my 55G tumble culture, I load it up: amonia, miracle grow, fish emulsion as well as iron, iodine and vinegar. Because of the fast growing macro in tumble culture, I dose three times a week. On frag growout and 75G display, I dose twice a week.

I have expanded the cultivars of macro in tumble culture. Initially, I grew Gracilaria Hayi with 6’ of LED light bar (fifty four 3W diodes). Because I wanted a different color macro, I reduced the lighting by removing a 3’ light bar to produce a dark burgundy color. Then, I added cuttings from Halymenia digitata, Dragons Tongue, that I am pampering to get into production. This species of Halymenia should grow very well in tumble culture. Two very good reasons for tumble culture is it is a self pruning/cleaning process that produces symmetrical bushes. That saves labor. From my point of view, the biggest advantage of tumble culture is that all surfaces of macro are subject to light and all surfaces take in nutrients. So, in my case, I was able to reduce electric bill and produce a more desirable product with a dark burgundy color.

I like it when everybody wins.

Subsea, very cool stuff. What do you mean by tumble culture? Specifically, how do you accomplish it? I get the general idea, but can't picture the mechanics involved.

What fish do you keep in those tanks? I think that I see black mollies in the pics...any others? If you add fish, will that alter your dosing regimen?

Vertical loop current

Because of the energy in the mass of inertia, a tumble culture has a source and an end. The trick is to get them into the same vertical plane. Long narrow tanks work best but there are other techniques for larger scale operations.

In a 55G tank, I start the energy at top left with two MaxiJet 1200. Current travels on surface from left to right. Current hits right vertical wall, then makes a u turn and flows from right to left at bottom of tank. To assist with uplift on left side of tank, I make a 45 degree ramp with course aroggonite at 3-5mm in diameter. The ramp starts out 6” before vertical wall. Four inches in front of wall, a curtain of air bubbles accelerate macro bushes up to MaxiJet discharge where the journey repeats itself.

In 55G growout tanks, I prefer only mollies. They are active herbivores but not destructive like Rabbits and Tangs. They are just like “big pods”.

I feed heavily. It is fun to watch the tank feed. With respect to changing feeding protocol with different fish loads. Not so much as watching the tank and seeing what it tells me to do. An obvious bio indicator would be GHA or cynobacteria.
