    Phosphates from water storage container?

    I like Caulerpa Prolifera in the substrate. It’s thin bladed emerald green fronds are very attractive. Keep it in the substrate as it’s holdfast are difficult to remove from live rock. Numerous red macros to choose from. I like Gracilaria Hayi and Bortacladia, Red Grapes. https://www.marineplantbook.com/marinebookprolifera.htm https://www.marineplantbook.com/marinebookgrachayi.htm https://www.marineplantbook.com/marinebookbotryo.htm

    Black box LED lighting

    Black box LED lighting

    First post! Welcome to NR. Will they work was your question? Yes, they will work, depending on what you put in your tank. I have always found that less light is better than more light. Let us address dimable. With only one controller, you can only change intensity and not spectrum. I would not want this light on my display tank unless I saw it up close over a tank with aquascaping. If the spectrum is not pleasing to you, I would not want it. When I use Mars Aqua, American made, I have two seperate dimmers. This allows spectrum adjust. Corals can adjust to light spectrum. PS: This light would be a great macro refugium light for a 20G long tank. Somewhere in the technical description should be its kelvin number. Mars Aqua fixtures are 1300 kelvin with both channels equal.

    Other names for eggcrate?

    Light diffuser. Sold in 3’ by 4’ rectangles. Perhapes other sizes. I have always bought it at Home Depot lighting. Could not find it at Lowe’s.

    Algae ID?

    If the purple spots that are everywhere are flat, hard and calcareous, then we are talking about coralline algae. That is a good thing. Not knowing where your live rock came from, I will not guess at what I am looking at. Instead, I will link you to the best information macro care & identification web site that I know. https://www.marineplantbook.com/

    Natural Filtration

    This automatic response of reduced macro growth in response to reduced nutrients is what I choose to call Dynamic Equilibrium as a part of Intelligent Design. Nature is very efficient at processing energy. Also, nature is very creative in how biochemistry and the “coral holobiont” works. Recent research has shown not only that corals feed directly on bacteria but that corals are selective about which bacteria they harvest. Not only does coral harvest a specific bacteria, but coral secreates an enzyme specific to the growth harmone of that particular bacteria. Did that coral just manipulate its environment? We have known for many years about the chemical warfare of softies and the stinging sweeper tentacles of LPS, now we have some coral acting as Master Gardner. As science reveals more facts about how our marine environment is a living, breathing system that is powered by photosynthesis but is maintained by the laws of nature, Dynamic Equilibrium, Now, we find that the creatures that are in this environment are manipulating it to their benefit. As Keeper of the Reef, my goal is to “balance the system” so that my display tank is pleasing to me with minimum effort on my part. That makes me a “Laissez Faire” reef keeper.

    Wet & Salty

    Thank you for the kind words. Due to many demands of my time, this tank is on auto-pilot. I am happy for Dynamic Equilibrium to operate the tank.

    Help Identifying tiny organism

    It loops like a miniature shrimp with eyes extended on stems. Without something next to it to contrast size, it is difficult to say. Google search for amphipods.

    The leap from freshwater

    Welcome to the hobby / adiction. I have been reefing for 45 years and I haven’t burned out. As @seabass said, keep it simple. I am big on natural filtration and on using Dynamic Equilibrium (Laws of Nature) to operate my reef tanks. One example of Dynamic Equilibrium happens during lights out as pH in bulk water drops to 8.05 with aroggonite beginning to dissolve calcium and trace minerals. Another example of Dynamic Equilibrium happens when carbon dioxide solubility shifts, absorbing more carbon dioxide gas as carbonate & bicarbonate alkalinity are maintained. So, carbon dioxide as an inert gas maintains alkalinity which combines with photosynthesis to produc glucose, which is carbon to grow coral. You don’t have to understand what I said to operate a reef tank. However, if you want simplicity and beauty then run a low tech macro lagoon using ornamental macros mixed in with LPS and softies. Very easy to maintain. The black box that was referenced is 165W rectangular black There are Chinese manufactures, however, I have used this American company. They are very reliable. Seems like it was priced at $90 less than 5 years ago. https://www.amazon.com/MarsAqua-Dimmable-Aquarium-Freshwater-Saltwater/dp/B017GWDF7E/ref=sr_1_3?ie=UTF8&qid=1529183322&sr=8-3&keywords=165w+led+aquarium+light&dpID=51iN-57evaL&preST=_SY300_QL70_&dpSrc=srch
  11. I like 2”. With a reverse flow, oxygenated water is pumped into void then up thru the substrate which negates downward migration of detritus due to gravity. I do not vacum this substrate, with one short exception due to cynobacteria.

    Watchu look’n at?

    Emerald Crab. They get quite bold.
  13. While this is not a dsb thread, I would like to expound on one case study, my tank. I had a Jaubert Plenum 6”+ deep for 25 years. Because of Red Planaria infestation, in which I treated twice with Flatworm X, I added large Melanarious Wrasse which handled flatworms and every othe detrivore in sandbed. After 24 years, my Jaubert Plenum with 6” sandbed failed. Over a period of 4 weeks I siphoned out 4” of sandbed except one small area to allow wrasse to bury.
  14. PaulB rails against dsb. He took his 45 year old set up down to move residence to Montauge Point at the end of Long Island. It was set up as a reverse flow with 2” of dolomite, because they did not have aroggonite in those days. I know success when I see it, so I set up my 120G new build with a reverse flow at just over 2” deep. I see no reason for a focus on denitrification which is what dsb focus on. I have meant Dr Ron twice. While I agree with his focus on worms as beneficial detrivore inhabitants, I see no reason to bring dsb into the conversation. A fully aerobic 2 sand bed of the correct grain size will cycle and feed your tank.
  15. Without embracing nutrientrient recycling, zero water change is unrealistic. I have gone more than a year with zero water change. At that time I operated 6” Jaubert sand beds and used calcium reactors. @seabass With respect to organic buildup in substrate, the right detrivore crew will process that and make live food for the tank. No need to take substrate out and wash it. That is the food stock for detrivores to reproduce spores and larvae.
