    The more I use the cubes, the more I am fascinated to find out exactly what we are dealing with....
    I am realising the article I wrote was really just scratching the surface... We are way past the point of determining whether it works, its more about the how...
    My primary interest is on the biomass and i would really appreciate a bit of assistance to gain insight..
    Although it took a bit to realise we are not dealing with the commonly accepted nitrogen cycle, the succes in a high O2 environment pretty much screams aerobic... Which kinda got me thinking....

    the word yeast and not bacteria has been toted around a bit too.

    Where does the yeast come from?
    Does it naturally exist in our tanks? Are cubes innoculated with it?
    Is it a marine yeast? Or is it a non marine yeast which can survive in NaCl and thrive in the presence of a carbon source...?

    Did a bit of reading yp and info is a bit scarce....

    as far as i am aware it's part of the "plastic pieces/bits" of the media, it's mixed with a special material that serves as the carbon source, well at least that's how the older versions worked.

    .. u've got my attention! i have ordered a kg for my 1000ltr even tho i'm still skeptical (although every1 is screaming 'success' on the other thread)..! surely these q's should be put to orca labs, after all it is their recipe..?

    i would say that the "plastic" obviously only would be plyable or "accepting" of the "yeast" once it has been heated, but the "plastic" needs to be a special "plastic" because it needs to be somewhat bio-degradeable, if not bio-degradeable then non-toxic to feed/accomodate, and also allow for new surface area to be in contact with the water, and it also needs to be a plastic plyable enough as to be heated to a lower tempreture to maintain the effect and effectiveness of the yeast or bacteria "food" without damaging/burning the "yeast"

    my english sucks today.

    most certainly found everywhere, evey the air we breath. I neeed to test air samples and do spore counts in the burchey to ensure suitable levels!

    Ok.... Thought about it did some reading and.....
    it is a Yeast .... Scientific papers have stated almost all yeast can grow in NACL concentrations greater than NSW....

    Also did some searching, it seem that yeast cells seem to obtain energy from parts of the Nitrogen cycle, but NO3 seems to have the greatest effect on their growth. Hey I could be wrong, I'm just glad them cubes work! Going to need a whole bunch for my new tank!

    Agreed - some of them really benefit from No3 and detritus recycling. There are heavy concetrations of yeast in sand beds. This is getting interesting.

    Yeasts are anaerobic organisms that require sugars for growth so ( and I might be speaking a a huge amount of rubbish here) the cubes might have a molecular structure similar to sugars, thereby providing food and the and NO3/PO4 providing the building blocks for growth of these yeast cells. So what do we get?Cubes start to get smaller and unwanted nutrients are used up as building blocks, giving off N2 and biomass that are used by corals?
    Ok, ok, I know there is a large amount of flow over cubes, throwing the thought of them being anaerobic out of the water, but maybe we have two types of yeast growing here? Bugger you @irie ivan and @KillerWhale. I am going to eat, my belly hurts!

    @KillerWhale ..... You gonna make us do all the work here?

    Any particular reason why yeast would colonise before bacteria..... I undrstand that in tank bacterial populations create NO3 (aerobic respiration) which in turn feeds the yeast again in a high O2 environment for assimilation of the Nitrogen in NO3.... ???

    A thread about effect on in tank populations comes to mind..... Are they working synergistically towards our goal....?
