    Hunting, fishing and reefing. At present, I have over 7000 gallons in salt water. At the end of Feb, I will have a grand opening for AquacultureRanch. Macro and live rock will be my mainstay.

    Red Macro algae ID

    Not sure. Look at GCE site under red macro. https://www.marineplantbook.com/marineplantbookredalgae.htm https://www.marineplantbook.com/marinebookasparagopsis.htm According to Russ Kronwetter this macro comes from Pacific waters and is variable in colors, depending on light subjected to. In the case of Bortacladia (Red Grapes are collected between 60’-120’), when I get it from the divers it is a dark burgundy. With brighter light it displays fire engine red then orange red, then yellow orange. All to often, it is subjected to intense light and loses its berries and goes sexual. IMO, Red Grapes do not look good under intense light. Second picture shows volunteer Bortacladia on piping at water surface. In a differrent tank, first picture shows volunteer Halymenia Dilatata at water surface.

    Gooseneck lamp for jar?

    You realize that mangroves are trees.
  3. I know your ponies will do well in a mono culture. Change is in the wind. I am adjusting outside mariculture to cold hardy macro algae: mostly Ulva because of its marketability.
  4. Consider this as nutrient enrichment. Amino acids are the building blocks for everything that grows. Amino acids are produced by bacteria breaking down proteins. Their are more than 20 different amino acids of which 2/3 are derived from animal proteins. The remainder of amino acids are derived from algae protein. Your tank is in the process to mature into a living breathing ecosystem that feeds itself.
  5. Shipping stress is a big deal. Macro has great regenative properties. I have had live rock for several years that all of a sudden grew ornamental macro.
  6. @yoshii I remember that first picture of blue scroll. At the time, I thought the colors were computer enhanced. Speaking about enhanced, how is academia coming along for you. Last I remember, you were in a graduate/doctorate program in Southern California. Soon enough, you will have more degrees than a thermometer. Good fortune on your journey.
  7. With respect to live phytoplankton culture, brands don’t much matter, fertilizer is more important. Florida Aqua Farm pioneered F2 formula for phytoplankton 30 years ago. http://floridaaquafarms.com/product-category/store/live-cultures/ You can get everything here. The chemical composition of micro algae (phytoplankton) is 116:16:1 of carbon/nitrogen/phosphorus. This relationship is called the Redfield Ratio. The chemical composition of macro algae is 560:30:1.
  8. Did you read the blog about feeding Sun Coral the same as an LPS. All coral do not eat the same size food. I am not an expert on this coral, however, I doubt it will thrive on phytoplankton. Feed phytoplankton to your pods and let them feed your Sun Coral.
  9. Capitalism works. However, the point was to turn display tank into a zooplankton reactor with NPS as the center piece of display.
  10. https://www.algaebarn.com/blog/corals/keeping-and-feeding-the-sun-corals/ [These are very hungry animals that (by many reports) can be “trained” to open for midday feedings when prompted by heavy spot-feeding. And indeed, spot-feeding may provide them with a substantial amount of sustenance (and be a lot of fun for the keeper). And they do seem to be able to capture and even ingest rather large amounts of food in short time. Nevertheless, like so many non-photosynthetic (NPS) corals, sun corals should be allowed to feed continuously as they are in their natural environment. Exclusively pulse feeding them may tax their digestive systems as well as be inefficient metabolically. Thus, the constant availability of a nutritious live food source will do much to maximize their health and reproductive rates. The easiest way to accomplish this is to establish a large, stable population of zooplankton within the aquarium system itself. The harpacticoid copepod Tigriopus californicus (e.g. Tig Pods) can serve this purpose well. These hardy, highly productive copepods adapt easily to ordinary marine aquarium conditions. Reaching a length of as much as three millimeters, it is a very large copepod species and is thus quite suitable for sun corals, which prefer a rather big bite size. Tig Pods, which are benthic as adults, may be ensnared as they crawl onto the coral; they also have a habit of skipping into the water column and may jump right into the coral’s stinging tentacles. Rich in astaxanthin, Tig Pods are an excellent source of the biopigments needed to maintain the coral’s vibrant orange coloration. Occasional offerings of high-quality Artemia (i.e. brine shrimp) nauplii can help to boost growth rates. If pod predation intensifies as the sun coral colony grows larger and larger, the standing pod population can be replenished simply by adding a new bag of Tig Pods from time to time. Maintaining high pod densities in this way will do much to keep to the sun coral (and likely many of its tankmates) happy and growing vigorously. What’s more, these pods scavenge heavily on detritus and undesirable algae throughout the tank, and so will be an important part of the aquarium clean-up crew.] After reading the above, I suggest you remove your carnivore fish from this tank, to allow pods to proliferate for 60 days. In that manner, your display tank becomes a zooplankton refugium that feeds SUN Coral. Once pods are well established, get an Algae Blennie for your fish.
  11. Jeff, you are very welcome. On a project of that size, start up a discussion thread, I would be tickled pink to get involved with the discussion. My marine engineering degree from 1974 introduced the chemistry but I read research papers on this subject matter. The more I learn, the more I realize how complex biochemistry is.
  12. Herbivores deal with nuisance algae. Nutrients is not very precise. Macroalgae consumes inorganic nutrients like nitrate, phosphates & iron by photosynthesis. During the same process, carbon dioxide gas combines with water to form bicarbonate molecule which is assimilated as glucose which is organic carbon. Coral & macro both leak dissolved organic carbon into the water. Cryptic sponges consume dissolved organic carbon and produce Marine Snow & dissolved inorganic carbon, both of which feed coral. A macro algae refugium would compliment a cryptic sponge refugium. Ornamental macro & coral in display would do the same thing.
  13. I also like the growth form of Pandina. @Lula_Mae Have you purchased Blue Scroll from lareef. Their footnote said they supplied small cuttings. That is not reassuring to me, unless I knew it was not recently cut and that it had started to regrow.
  14. https://www.lareefs.com/products/blue-scroll-macroalgae My experience with Pandin is that it is a slow grower. In reading the link at lareef, they say blue scroll grows fast even in low light. In my experience, Pandina needs medium to bright light.
