What is in the seaweed?
When I grew Graciilaria Parvispora ( Red Ogo) commercially, I sent it off to a scientific lab to be analyzed. It is my belief that seaweed will absorb anythig in the water. I expected the 30:1 ratio of nitrogen to phosphorous but not the 5:1 ratio of potassium to nitrogen nor the 2:1 ratio of sulphur to nitrogen. I am rethinking my nutrient dosing procedures.
Gracilaria Parvispora dry weight analysis: Nitrogen @ 2.50% Phosphorous @ 0.082% Potassium @ 13.54% Calcium @ 0.555% Magnesium @ 1.163 Sulfur @ 4.82 Zinc @ 139ppm Iron @ 107ppm Manganese @ 20ppm Copper @ 7.0 ppm

I'm surprised given the amount of testing and dosing of things like Ca/Mg/Alk that when someone asks about bumping their nitrate up the stock answer is a rather imprecise feed more. Adding inorganic nitrate via NO3 has the benefit of being exactly calculable to a specific ppm value and not being derived via the nitrogen cycle it has no impact on BOD (biological oxygen demand). I do appreciate adding more food has other benefits such as providing the corals and filter feeding animals with additional particulate matter but it all depends on your goals

Bugs Rule! Fascinating how research is proving some of the observations and conclusions of aquarists like Paul B and Steve Tyree. Rohwer's "Coral Reefs in the Microbial Seas" is an excellent place to start. The stuff done by Dr. Andreas Haas* showing the roles algae have in promoting heterotrophic (oxygen depleting) microbes and corals promote autotrophic (oxygen enriching) is a real eye opener on natural filtration in our systems.
De Deoij's** cryptic sponge research may be a bit off topic but proves Tyree's ideas on cryptic zones. *http://www.ncbi.nlm.nih.gov/pubmed/23882445 **http://www.rug.nl/research/portal/fi...letethesis.pdf

I'll bite. "Natural filtration" a.k.a. cultivating organisms for nutrient export, has always been a sub-set of reefing, and has its origins in the planted aquarium world. (hi-tech planted aquariums are nearly as extensive as reefs.) However, the examples of "natural filtration" that usually furnish the conversation are larger aquariums which have been established for many years. It's true that many large, old, successful aquariums run with little to no protein skimming, but that's because they are large, and established. Our water to bioload volumes are so astronomical compared to the natural reef that anyone who attempts to start an aquarium on "natural" techniques alone is more than likely doomed to disappointment. We need the "hi-tech" mechanical and chemical filtration because our bio loads for a given water volume ratio is so high.

I have 25 reef fish in my 75G Jaubert Plenumn on top with mixed soft corals and LPS. What do you call a high bio load that requires hi-tech mechanical and chemical filtration?

Very cool!! That's approaching "aquaculture" in terms of density! But, yes, that's the level of density I was referring to, nicely done if you're doing it naturally.
Quick question, if you are setting up food webs, have you used anything besides Phyto to increase the levels of copepods in your aquarium? I always wondered about dosing yeast, but have yet to try it. Thanks for your reply!

In the 'nano' reef tank world, there are examples of relatively large biomass to what most would consider tiny volumes of water using 'natural filtration' methods (only live rock and live sand) that have run for many, many years. As with most reef systems (but especially important for these small tanks), some hobbyist intervention is required via regular water changes and detritus removal if one wants the system to be at it's best.

Couldn't you just grease up your elbows and do the work? Keeping a happy healthy reef tank for years on end in not that difficult if you are willing to do the work. (no refugiums, no ATS etc)
Just as an example. if you were to walk into that MACNA and see two healthy tanks right next to each other. Both of the owners have been given all the bells & whistles. The guy on the left is all about a KISS, the guy on the right is all about that "technology." Who would you rather talk to? It sounds to me like the guy on the left has got more money in his pocket. It's kind of like chess. Why win in 10 moves when it can be done in 5? If that's not an "Intelligent Design" then I don't know what is. Last edited by AlSimmons; 08/14/2016 at 05:33 PM. |

Yes indeed, bugs rule. I would have thought that Steve Tyree's cryptic zone filtration included bacteria as much as sponges.

Not seeing any nice looking NPS tanks on your website.
Google results for that phrase returns back one result that actually fits the description. It's a very nice looking 10g tank that's a year old with no update after that. Lots of water changes and media changes. |

I know Charles Delbeek well. He no longer works at the Waikiki Aquarium, but there are plenty of big skimmers there. They also have access to natural sea water and can make their tanks open system if they need to. Not really a very applicable example to closed systems.
I still haven't seen a nice skimmerless NPS tank. |

https://************.com/2012/09/16/...-coffee-reefs/ Excuse my ineptness with computer posting. If this link does not work, then google Mark Van Der Wal, skimmerless with SPS and NPS dominant reef tank. PS. The link I provided is at Reef Builders web site.

What exactly are you looking for? I never said that I had NPS biotheme tanks. I said that skimmers would be detrimental to a NPS biotheme tank.
Also, if you googled Mark Van Der Wal, you would find a skimmerless SPS/NPS tank on the Internet.
