    Stunning tank!
    This guy must have a lot of time to be able to keep that tank in that condition & feeding all those gorgonians!

    why? its simple, this hobby is not that complicated :)

    he even adds PO4 and NO3 to his tank

    Wow indeed - are you considering something similar with your new setup dallasq?

    i never do water changes, i run a mix match of things that work for me. bio-balls, ceramic rings, bio-cubes etc.

    WHY do people do water changes?

    thats what everyone tells them to do :)

    i will get shot for that....

    all i know is that they cause in-stability and i can see it in my corals
    i wont start this debate again, it goes no where

    I think its more to do with his brilliant understanding of water chemistry.....the fact that he doesnt do water changes is rather insignificant....

    I think the larger the tank the less need for waterchanges due to biodiversity and bioload

    Interesting setup.
    But looking at his fish, he do not have a lot. Something a lot of use reefers cannot say at all. He is running a very light bio-load as far as fish is concerned.

    The difficulty is not the problem at all... Its the time it consumes to keep everything running (I run everything as simple as possible on my nano systems & it still takes up a lot of my weekends to maintain them!)

    & i don't fully agree that its "simple"!
    It took me at least 2 years of marine keeping & continuous studying of write-ups, studies & tank threads before i could even consider myself a successful reef keeper (not even well experienced yet). Ive been keeping reefs for 4 years now, & only now start seeing the bigger picture of all the aspects of keeping a reef happy! ()

    Lol, ive also added no3 to my tanks before, but that was for a whole different reason...

    exactly that can hold true for everyone

    my nanos receive the same treatment, in smaller water the change in params etc is greater so bigger in-stability

    thats irrelevant, doing WC for nutrient export will never work unless in weekly large percentages, having nutrient problems is because generation is exceeding consumption, so making 0.1ppm of PO4 a day, a week that 0.7, and if you have a starting PO4 at 1ppm, thats 1.7ppm at the end of the week, and do 20% waterchange that leaves us with 1.36ppm, then the next week we have more to remove... so while we wasting money on salt, RO and time, i have cubes which remove most as my test kits show 0 and it cost me nothing in time and cheaper than salt. never mind the param swings in Ca, Mg, Alk etc

    most do water changes as that is what advised to most beginners, same was told to me, and yes in the beginning i did them until i ventured to dig deeper...

    obvious that his current filtration system can handle the waste by his fish numbers. He got a big system, a lot of rock. So the amount of PO4 added to the system can be handled.
    How can it be irrelevant?
    Overstocking that same system with fish, and lets see where the PO4 reading go. Instead of 0.1ppm of PO4 a day, what happens if it is 1.1 per day? Will the same filtration system, still be able to handle that extra fish poo? Even your bio-cubes at some point will not be enough. Have to add more cubes, bigger refugium, or what not.

    He also has a very good understanding of water parameters and test for a lot more things I ever done. Plus dose a lot of things.

    Your remark of irrelevant on my comment of lightly stocked tank, could be seen as an OK to overstock systems and believe that your filtration would be able to handle it. Does not matter what you use. There is a balance point.

    the amount of time I spend so far this year on my tank, doing any maintenance other than cleaning the front glass, is minimal. I simply do not have the time to spend per day, doing water tests and dosing, that is required to run a system as successful as that tank. It is simply better, quicker and less hassle to do my water change.

    I sure believe that it can be done, his tank is proof.

    I might achieve / replicate his success, if I reduce my fish numbers.

    Look at Irma system, beauty of a tank, best of it all, its runs without a sump!. With hang on back skimmer. But look closely, no big fish, but a number of smaller fishes popping out everywhere. That is her "secret"

    looking at Irma and Glennf, that is a similar thing between them.

    Those are Indo-Pacific photosynthetic species, Rumphella and Pinnigorgia. Same requirements as tree-type soft corals and they don't need feeding.

    for those who dont do waterchanges...what do u add to replenish trace elements etc?

    i havemt done a water change in months..lol

    i had a few problems..but then i just left the tank alone and stopped fiddling...The tank has now settled down on its own...it actually found its own balance without my fiddling around..
