    Hi guys... Im currently in the market for some specialist advice on keeping LPS corals in a SPS dominated ultra low nutrient system...

    Some background:
    Ive had my 130l DIY nano aquarium now for almost a year now. It has been running very stable since day one & ive had some great success in the aquarium!
    My goal for this aquarium from day one was to create a brightly colored SPS only aquarium with some LPS corals to fill the gaps. But having a very busy year in 2012, i decided to keep to a mixed reef until i could start the LNS SPS tank...

    Currently:
    November'12, i decided it was time to start the transformation to low nutrient system & moved all my fish to my refugium/frag tank.
    I removed almost all my polyp, mushroom, LPS & gorgonian corals to the same tank & added ORCA Nitra guard normal + titanium to the tank to start lowering nutrients,
    Within 2 weeks, my nutrients were undetectable on any of my test kits.
    This was just before i left for holiday. So i left my sps corals in the tank while i was gone...
    When i returned from vacation i january, all the sps corals colored up beautifully & almost all the algae i use to have vanished...
    So 2 weeks ago, i started transforming my aquascaping for the new setup.
    I built a new "improved" sump & replaced my 150w mh bulb.

    My question is this:
    Im still busy with my scaping & adding sps corals.
    I want to create a LPS "corner" in the tank (especially euphyllia species) as i have 9 different beautiful specimens which i have been nurturing for a while now.
    Will the LPS corals survive in a ultra low nutrient system or will they fade away...
    If possible, what procedure should i follow to keep them happy?

    Looking for some specialist advice here please as this will determine my whole aquascape & coral placements...
    @irie ivan, @Nemos Janitor ?

    This is a picture of my tank before i started the transformation...

    im tagging along...I found that when i dropped my No3 and Po4 to undetectable my LPS went into a sulking mode...Would love to know if there is another way...Freaking Nice Setup....

    I suppose low nutrient is defined by the test kit. Or is it defined by the lack or food presented to the corals. Or the filtration system.

    Please give indications of nutrients at the stages you talk of.

    Tank looks great BTW.

    A small input from my side.... Been running my system the past few months on "low nutrients" , but not ultra low as I cannot seem to get it to ultra, but had to raise the nutrient levels a bit as the corals all looked fine in the beginnining, exposing nice colors, but for some reason it was looked as if the colors of the Lps almost "washed out", not talking about bleaching though, but similar color.... Coral are all happy now again, seems to me the corals who suffered most, was the torches, frogspawns and hammers with one or two doughnuts in between....
    I do understand the effect of low nutrients wrt algae strains etc preventing photosynthesis to properly take place, blah blah blah (Irie Ivan can go into this)... But again, this is what I have noticed in my tank, I am no boffin when it comes to ULNS! , I did check my parm as I thought it could be something else, the parm were all in check, as a matter of fact, the tank has been very stable over the past year or so.....
    @Irie_Ivan, question for you, when running LNS, would algae die off completely? Or also bleach?

    I am thinking along the lines of the ambient nutrients in the tank are LNS and the inflow nutrients are fresh new nitrates. This requires controlled filtration. Time will tell here.

    However in this tank I feel the halide has a big say in the success.

    At 10ppm you could keep the color with a mh, even 5ppm should be fine, more feeding will help corals, goniopower or the likes, I ran my tank at 4-5ppm NO3 and 0.05 - 0.1ppm PO4

    Coloring can also be a response to high uv and bright light , think sunscreen , so by keeping Params stable and water clear you should be able to keep great sps and lps

    Nutrient control is very important in coral growth and reproduction. I am going to stress this....Depending on species kept, it is the nutrients feed rather than the ambient nutrient level of the water column.

    In other words, one could have a LNS by having a very efficient filtration system and have a very high nutrient input. Or one could starve the corals by having a LNS system with a zero nutrient input and poor filtration or very efficient filtration. All are considered LNS systems.

    It all boils down to controlling. Feeding your filter to maintain nutrients or controlling filter to maintain nutrients.

    The point to consider is that a Tupperware box with lunch four days old is killer food. Marine life feels the same, they need fresh nutrients not some some weeks old built up crap.

    Damn... Should have gottn in before the old man..... Yes, keith is right.... Its all about the light... But i was gonna blah blah until i get there...

    LNS, ULNS, I have to wonder when somebody is going to put an actual definition to it... At which point of N and P does the water in our pseudo reefs make the transition from Low to Ultra Low? The question has been playing havoc with my last remaining brain cell(s?) since the advent of mainstream probiotics and carbon dosing....
    Probably due to these systems allowing us to reach what Gary White puts so nicely as pseudo ogliotrophic conditions in our tanks.. When one looks at the word ogliotrophic, one can See where the terms ulns or lns comes from:

    Coral and Coral Reef - Environmental Setting And Requirements - Water, Corals, Growth, and Light - JRank Articles

    [/QUOTE]Corals thrive in oligotrophic water; that is, water with low concentrations of nutrients such as phosphate, ammonium, and nitrate. Currents and wave activity help supply the continuous but low concentrations of nutrients that corals and algae require for survival, while also removing Waste materials.

    I did the whole ULNS system. NO3 and PO4 were undetectable. My frogspawn, hammer and trumperter candycane took a major beating. Since my new tank, NO3 is higher and all are looking much better and are recovering.

    I am not chasing numbers anymore, I have good colours in my tank, and good growth.

    Please could you give us more info on how this is done and where one would get no3 and po4 from. Ive read about this before and have always wondered it

    A good skimmer, ORCA nitra guard biocubes, gfh and as much flow as i can afford.. And ATI easy vital, a filter sock and some GAC.
