    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. Algae would dominate every wild reef in the world, if it were not for herbivores. While it may seem counter intuitive, do not starve your tank to get rid of undesirable algae. Use janitors to remove algae. Sometimes you are the biggest Janitor with a syphon vac. I recently found a proper macro algae fertilizer from Florida Aqua Farms. They wrote the book on Guillard F2 fertilizer. Marine algae’s, as a rule are much mire nutrient hungry than land plants. All photosynthetic organisms in the water are limited not by the most abundant but by the least in supply. Check this link for a macro algae fertilizer cocktail. I would appreciate your thought. http://floridaaquafarms.com/shop/plant-fuel-and-plant-fuel-too/
  2. With respect to Dino, it is one type of phytoplankton. I hope you find this link intetesting, I did. http://www.fondriest.com/environmental-measurements/parameters/water-quality/algae-phytoplankton-chlorophyll/
  3. I really enjoy reading the dialogue on your thread. Your philosophy on reef keeping is very relaxed: less technology/more biology/less maintenance. I so much enjoy seeing the beauty in your mixed garden and of hearing “cat antics”. I need to go back further in your thread to see how you got rid of your algae problem. I use a lot of differrent janitors, somethimes the biggest Janitor is me with a tooth brush & hydrogen peroxide.

    For 500GPH, I don’t think you will find much smaller.
  5. Natural Filtration

    Referring to “growing coral quicker” article by Dana Riddle, his second paragraph caught my attention. Liebig’s Law states, “not by the concentration of the most abundant element but by the supply of the least abundant”. Dana focuses on alkalinity as the building block for coral. Alkalinity derived from inorganic carbon dioxide. I liked this best, “Photosynthesis is the link between the inorganic and the organic worlds”. With my use of aroggonite sandbeds, I have supplied soft corals with all the alkalinity required. When hard corals build their limestone shell, they consume huge amounts of alkalinity. Because of their increased demands on system, I always stayed away from them. However, with the use of a calcium reactor using carbon dioxide to dissolve aroggonite is a perfect two punch system. You are getting the minerals from aroggonite to support alkalinity and you are also supercharging your system carbon source with glucose from photosynthesis.
  6. Natural Filtration

    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4286716/ I have been encouraged to keep some of my comments about biological filtration in one place. It allows for a much better platform for discussion without infringing on someone else’s post. While the above link deals with the complex overall picture of one part of what happens on a natural reef. Through complex food webs involving bacteria and algae, the reef feeds itself through “carbon fixation” in which dissolved carbon dioxide converts to carbonate & bicarbonate that when coupled with photosynthesis produces glucose, which is a carbon source. This link shows how carbon is transferred in a system between the primary and the secondary producers. I just found this link and will study on it more. In the “significance for a reef tank” section, at the conclusion, the author states, “DOM from coral is rich in proteins & lipids and DOM from algae is rich in carbohydrates. Algae DOM is essentially junk food.” I found that very interesting. It agrees with a thread on RC with Stee Tyree and my friend Timfish concerning cryptic sponges. Previously, my answer to algae DOC is to use GAC and prune macro (seaweed). Well, four months ago, I turned out the lights on my 25 year old 30G EcoSystem mud/macro refugium and seeded with cryptic sponges. It was already mature with pods, micro stars, feathers and worms. http://www.advancedaquarist.com/2017/9/aafeature With this article, Danna Riddle shows that the stony coral, Porites lobata increases photosynthesis of carbon with ammonia over nitrate required by other corals.. http://www.advancedaquarist.com/2017/2/aafeature The link below is the starting point of my discussion. It defines how carbon dioxide is utilized by coral building zooanthelia. I don’t agree with adding organic carbon to a reef tank and indirectly this article supports my conclusion, that organic carbon dosing in a reef tank fuels bacteria, which consume/transfer 60% of the energy in a reef tank through the “microbial loop”. After reading these articles, I consider using calcium reactors in all reef and macro tanks that I own and running UV sterilizer 24/7. I don’t use the sterilizer on my 25 year old tank. I do use sterilizer on everything else. http://www.advancedaquarist.com/2016/9/aafeature
  7. BioCube REfuge and Canister filter

    Thank you for the insight. I found myself on a beginners forum giving advice, which as you pointed out is easily misapplied. Because I see a tendency in this hobby in calling nutrients bad, I get concerned with this foundational thing and I respond, perhapes too passionately. I, like you, wish everyone to be educated in maintaining reef tanks. Perhapes sterile is good. I never thought it was.

    https://www.marinedepot.com/Danner_Supreme_Aqua_Mag_5_Water_Pump_Fixed_Flow_Aquarium_Powerheads-Danner_Mfg.-DN1123-FIPHFF-vi.html see if this works for you.
  9. BioCube REfuge and Canister filter

    Who cleans a refugium? @Whisenhunt My 30G EcoSystem mud/macro refugium has been set up 25 years. No cleaning it, ever.
  10. All fish died, d*mb accident. Why?

    The pump was not the primRy issue. The filter box which the pump circulates water through was the issue. With little replacement water from display tank (high in oxygen) the chemistry of this stagnant water produced hydrogen sulfide, which is lethal.
  11. BioCube REfuge and Canister filter

    Consider starting a journal for your tanks history. It is never too late to start. when you say refugium, as Seabass says, they can be designed for differrent purposes. A chaeto refugium would support pods and allow you to perform nutrient export. I like mud in my refugiums because of the differrent size live food produced.
  12. Dawn's multi-level seahorse garden.

    Love the pictures. How patient to get the second picture with side by side twins framed with twin gorgonions branches? That picture needs to be enlarged and detailed. Really great picture with texture and color. On the first picture, what is the red plating thing?
  13. maxi 1200 nano 28 help

    That’s the difference. It is crazy that your model cost $4 more with less options. I saw them both on Amazon.
  14. Macro algae?

    It is not unusual for macro or for that matter Coral to volunteer. I have had diver collected live rock for 8 years that started sprouting differrent things when moving rock around. I have also had red grapes go sexual and sprout out two years later. you have too much blue to help with ID. Instead, you ID it from two links I will send. https://www.marineplantbook.com/marineplantbookgreenalgae.htm https://www.reefcleaners.org/nuisance-algae-id-guide
  15. All fish died, d*mb accident. Why?

    I think that some crud was left in bottom of filter box. This allowed hydrogen sulfide cell to develope. Once water flowed thru the box, the concentrated initial flow was in the path of yellow tang, afterwhich hydrogen sulfide dissipated with oxygen and volume of display. In the case of the evo 13.5 built in filter box with stagnet water for a week. I would think that this water would be oxygen depleted and very likely forming hydrogen sulfide cells.
