    I would like to start of with this link from Practical Fishkeeping:

    Frequently asked questions on Ultra Low Nutrient Systems | Features | Practical Fishkeeping

    With my little experience so far, I find using Vodca and Biodigest dosing very easy.

    Benefits:
    1. Being able to keep SPS.
    2. Great color for SPS.
    3. Reduction of algae growth.
    4. Bacteria serve as food for corals.

    Now, what are the disadvantages from your experience? I am thinking of no need of cleanup crew as there will be no food for them to eat? Surtain corals cannot be kept because they need some nitrates and phosphates?

    Thanks Dallasg. Now, why would many websites say that nitrates and phosphates should be 0 for example the hammer coral? Should they not say, a bit above zero?

    from what i have gathered running the ULNS way is that the water is kept very sterile and alot of food and amino acids etc are added to keep corals growing.
    the sps corals are kept on the edge of living for lack opf a better word hence the great colours, the zeovit additives "burn" away the useless zoo algae allowing colour burn.

    LPS do like good water, with nitrates and phos close to zero, softies and coralimorphs are more forgiving.

    nitrates and phos have to live together to be reduced and kept close to 0.

    I want to have an economical mixed reef. So, Prodibio is easy and economical. Will just go with some easy SPS then.

    Nope, vodka is a carbon source for bacteria aka food

    Some mix vodka, sugar and vinegar

    @Tremayn i really doubt zoas will stop growing because of ULNS as i have seen sps systems with some crazy zoas as well. check out sunnyx 1st rimless reef

    The trick to ULNS is feeding heavily and adding a lot of ammino acids. If you stick to this then you could keep any corals. That's what I believe and it has worked for me.

    I agree, I have a ULNS system that has a mostly Zoas and shrooms and they love the fact that the water is clean, but man, do I feed the tank!!!
