    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.

  1. First, I know little of your husbandry skills or experience level. Second, I have no knowledge of your tank. If you want informed comments, then you must present sufficient details for your situation. With respect to nitrogen, everybody, including corals, needs nitrogen in one form or another to grow. To my observation, you are chasing numbers. I suggest that you stop doing that. I have not tested those parameters in > 30 yrs. A healthy bio filter takes some time to mature. Remember, coral are a part of the biofilter. Also, in looking at those numbers, your nitrifying bacteria have cycled. Bacteria should be feed to grow. No need to provide “more real estate”, only food is necessary for bacteria populations to increase.
  2. Red White and Blue

    I have used every technique that my 45 years experience has given me to recycle nutrients thru complex food webs which produce live foods in this tank. On this 75G tank, I feed heavily with flakes, frozrn mysis but each day, I feed one live oyster and one live clam to tank inhabitants each day. When I add the oyster juice, every filter feeder in that tank comes alive. I also dose 75ml of vinegar twice a week as well as trace addition of iodine and major trace addition of iron. At 25 years maturity, the Jaubert Plenum has begin bealcing detritus for the last 6 months. Everyone of my sand bed janitors has been eaten by the introduction of a Melinarious Wrasse 18 months ago coupled with lack of sandbed maintenance on my part, has caused a dirty sandbed. To that end and because I have no need of a dsb for denitrification, I am siphoning out gravel from 6” deep to 2” deep. also, the 30G ecosystem mud macro refugium has been converted into a cryptic refugium. Three months ago, I turned out the lights, composted tomatoes with grape caulerpa, added dry rock, then some rock seeded with cryptic sponges. Why cryptic sponges. You might have to get the Sponge ebook by Steve Tyree or a marine micro invert reference source like your phone and google search. I will try to explain. There are > 8000 species of sponges, some as differrent as night and day. I grow as much diversity of live food in tank as possible to offer as much variety as possible. Specifically, with respect to cryptic sponges, they consume DOC and produce DIC with is a nutrient source for coral and macro. Cryptic sponges also produce a type of gel that is often discribed as “Marine Snow” So, yes my tank produces live food for tank inhabitants.
  3. Hum. Bacteria don’t need a designated space. They will grow in the water column as well as stacked up on top of each other. In my unlit refugium, I will use eggcrate to colonize bacteria and cryptic sponges. Martin, I should ask you for your reason to increase bacteria in your sump or refugium. IMO, bacteria and phytoplankton are foundational for every marine food web.

    I don’t know how long the flame scallop is going to stay there, so I will take the pictures now.

    Snow at 29 degrees. Water temperature at 60 degrees with 900W of heat input. I need to cover tanks at night. Snow at 29 degrees. Water temperature at 60 degrees with 900W of heat input. I need to cover tanks at night.
  6. De-Nitrification. Is it required?

    There are more than 8000 species of sponges. There are great at filtering water. In the case of Cryptic Sponges, they remove dissolved organic carbon. yes, I like the decorative sponges. In addition to Red Tree Sponges, I recently got Yellow Ball Sponges and Orange Encrusting Sponges from live plants. Gorgeous stuff. I’ll take pictures when lights come on.

    I have used Rid X. It is a fact that many bacteria can live in fresh and salt water. I would agree that nitrifying bacteria should not have to be reseeded. I am in conversation with TLC tech services to get details as to what bacteria cultures are in product. If it is snake oil, I want to know what kind of snake.
  8. De-Nitrification. Is it required?

    I now have some evidence of either a mantis shrimp or a gorilla crab. A dead Emerald Crab was noted on tank inspection this morning. Attacker came thru bottom of emeralds shell. Aside from dismembered claws and some body cavity damage, best I could tell, nothing was eaten. I assume it happened shortly before I looked into tank during lights out at 6AM. What night Predator is a suspect. Remember, I got Gulf uncured live rock 2 months ago.
  9. Great vidio. As I was just waking up with my first coffee, at the very end of the vidio, I imagined a giant cat head.
  10. Bayer for coral dipping

    I have used it to dip macro. Understand this about Aptasia, this dip will not kill them. I have also used a bath of 10% hydrogen peroxide for < 10 minutes on corals to kill everything including macro and that will not kill Aptasia. For Aptasia removal, their skin must be penetrated. I use a tooth brush soaked in hydrogen peroxide.
  11. How to tell if macroalgae is getting enough light

    Less light is always better than more light. With red macros like Dragons Tongue, Halymenia digitata, under intense light the top is red and orange and the bottom is a dark burgundy. I would expect your green macro to be darker in shaded area and lighter under intense light. That is pretty much what I see on land plants.

    https://www.tlc-products.com/productscience/ I just dosed a start up dose of bacteria “StartSmart Complete”. Why. Because I believe that the foundation of live food on a reef is bacteria and phytoplankton. If you read the science behind the bacteria, there is a section on bacteria density growth rates. If bacteria A takes 30 minutes to multiply and bacteria B takes 60 minutes to multiply. In five hourss, Bacteria A will outnumber Bacteria B by 30 fold. Is that bad, it depends on the bacteria.

    I now have some Red Grapes that have photoadapted to brighter light. Last year, I received Red Grapes from Divers that was a vibrant burgundy color. When exposed to brighter light than they were collected in, the foliage turned orange, dropped flotation balls and dissolved. I thought only fast growing macros went sexual. Well obviously not. So, this year, I am cultivating Dragons Tongue, Halymenia digitata. It is gorgeous and lives light. There are hundreds of red grape starts including shaded areas of HOB overflow weir and bright spots as well. I moved an acrylic bracket to a separate tank with more light and it is very nicely photoadapted t9 a bright fire engine red.
