Could we utilise the Redfield ratio a little better in aquaria?

Fuel...............................Fire.
I'm going on R2R Vacation until this thread stops.

16:1 that is a not true!

Dude, just stop with your "limited" everything. We cant test for DOC so you can't say it is true, youre making assumptions without basis

Co2 is inorganic carbon. Dosed carbon sources are organic carbon. Organic carbon is limited in aquariums compared to other nutrients.

I think you may have missed the the context of the exchange here as it relates to what was said 10 pages back.

The OP appeared to not understand the difference... to the point of telling us what "C" stands for.

Of course C is for cookie... but I digress.

People will laugh but you are actually correct about this. Companies pay a lot of money to put their own users on forums to cause chaos along with other state actors as well. I applaud you for being aware of this.

It’s unfortunate as it distracts the focus of the discussion.

As far as Redfield goes my advice to you is this. I believe that redfield says that a particular phytoplankton is made up of carbon nitrogen and phosphate. If we feed our aquariums regularly we typically have an abundance of nitrogen and phosphate. But the food lacks enough carbon to provide dogestion for everything else in the aquarium. Simple carbon sources will provide a boost to the bacteria for digesting the nitrogen and phosphate in the aquarium. I hope this helps.

This is the basis of the discussion. Fully agree

Hey Staff, this thread should be closed for review.

The point here is that Redfield really has no relevance in context to that dosing, as there are multiple consumers that consume at various ratios. It may help if you start at the top of the thread and try to follow what has transpired.

It is slightly relevant. Let’s say you want to promote the growth of bacteria and phytoplankton in your aquarium. It’s important to know that these things need organic carbon for growth. Also organic carbon is usually limited in our aquariums. So dosing organic carbon is typically helpful.

I’m not sure what YOU aren’t following here?? I don’t agree with everything sixty is saying but he’s got the right idea and the spirit and everyone just seems to be intent on dumping on him instead of being helpful. Why do I need to read multiple posts of you not helping here in order to follow this conversation?

Pease don’t take the experiment out of context, I’m only going to evaluate the saltwater nutrient consumption in my experiment.

How will you do that if you cant measure DOC and cant measure total Nitrogen reliably?

Im using a carbohydrate made by myself, I should have a vague idea of the carbohydrate content of that same solution being used in ppm in relation to Nitrate and phosphate.

You know what it is at the start maybe, but not after a certain amount has been taken up by the organisms

Initially the test will be fully dark, to evaluate the organisms demand in seawater and to remove photosynthetic interference.
I’m not using any aragonite based products in this system to remove the phosphate absorption capability of aragonite that could interfere with the results.
It’s also my intention to spread the dose of DOC over a period of 24 hours to mimic the slow release instead of doing it all in one shot.

And yet again you choose not to answer

I thought I did.

How hard is it to answer one simple question?

 

[sixty_reefer]

I’ve mentioned before, I know the ppm in the DOC solution and I know the ppm in the nitrogen solution (I also will know the ppm in the phosphate solution) that should be all converted to nitrate by nitrifying bacteria and have a indication of how much nitrate is removed by bacteria or Protozoa.
Weather is just one or a collective work between bacteria and Protozoa I don’t believe it affects final results as both will be present in seawater imo.

So at the end you'll have no nitrate left, what then? What will you have learned? That something in the water uses nitrate as fuel, nothing else. Maybe that phosphate is used as well but we know this happens already

The target is not zero, the focus of the experiment is to evaluate the consumption of nutrients in ppm on a balanced environment by saltwater only.
Also referred many times in the hobby as import export.
From that usage in ppm I can then evaluate if certain ratios appear for saltwater nutrient demand in a tank.
From there coral and other photosynthetic organisms could be added and evaluate if the demand changes.

I've still no idea what you are trying to achieve but why are you using algal derived sugars? Why not plain old terrestrial sugar?

I quit (again). This makes no sense and is a waste of time
