Is there any food for it in the sandbed?

It's also generally the rate at which carbon dosing will remove nutrients, as the bacteria formed during this process builds in these ratios.  So, by adding carbon, you allow the bacteria to use the nitrate and phosphate to multiply.  Then skim it out.

Yeah I did read at some point that bacteria has a different (lower) N to P ratio, but 16:1 certainly seemed pretty close to my results.

Please elaborate


A.

If you take some phyto plankton and analyse the make up,  it will usually correspond to the redfield ratio (which is 106 carbon : 16 nitrogen : 1 phosphorous, note: not nitrate and phosphate).  However, that does not mean that the water the phyto lived in necessarily also had that same ratio. 

The relevance to us is that there is (what I now consider to be) a myth that we also need to maintain their water at these ratios.  Don't get me wrong, the tank seemed fine when I tried it, but no better than the numbers I keep now (phosphate around 0.03 and nitrate around 5).  I can't remember off hand the factors you have to use to convert nitrate and phosphate to nitrogen and phosphorous, but if somebody does, I bet they're miles out from the RR.

No need to delete the post, it might be useful for others.

Also, a minor point, but it's the ratio of elements in phyto plankton, not sea water

Just remembered- but can’t delet my own post 😩😩
Redfield Ratio was what I was looking for

The widely recognised link ratio 16:1 I think that a paper has been published on
It’s often used but I can’t remember the name “ redit “ or something like that - mind you could be way off

It explains the ratio of elements in sea water and is a basis for how marine tanks work

I am after a bit of help if possible. Yesterday and today my sea cucumber keeps doing this, going flat. Does anybody have any idea why.
