    hi all

    in my previous setup I used a large dsb with refugium and found it to work really well . I am working through some ideas for my new setup and came across something really interesting .

    could anybody gimme some more info on the concept of ecosystem refugiums and how effective they are . what are the best mud that can be found locally to use and where to get it , the best refugiums plants to use that can be easily sourced and that will not leach all the calcium from the watercolumn . I also recall reading that bioballs were used in the mix .

    I consider you guys to be some of the more experienced guys on here
    any advise would be appreciated

    hi...
    your goal nutrient control, nitrogen cycle control or both?

    I would like to keep sps amongst other corals and some selected fish so nutrient export and keeping the nitrogen cycle going would both be a must . A good skimmer and and phos reactor is also part of the plan as well as some dosing of the usuals ...

    if you planning on going a natural route, it will take time for it to mature, while its like a cycle, i would add the refugium and skimmer and let it run for 1-2 months with just LR, algaes, 1-2 soft corals and 5 chromis, this will let the system establish and kick in with enough bio-load for the cycle and refugium to kick in...
    there would be no need to phos reactors etc if you took your time etc

    i am at the same cross-roads and thinking of making my setup run less dependent on chemicals etc


    so maximize sump for refugium, a place for the skimmer and return. i would have the refugium first to act as the mechanical and biological filter with some cuc in there to help with the larger waste. then flow through a mechanical filter then to skimmer and return.

    this idea has endless combinations and possibilities

    From what you're telling me it confirms my ideas to be sound . I had a nice big dsb with refugium over it an in time the little critters populated my sump and then migrated to the dt so in time as the whloe setup matured it worked well .

    One of the things I would love to know is if adding a layer of some kind of mud or peat or something similar on top of the dsb would optimise the system or just botsh things . I also tried all sorts of caulerpa and though it all grew well I couldn't really find the distinction between them ... One thing I did find was that they all love calcium so what reef grass could you suggest

    have you thought about mangroves.. I've read they do a fantastic job on nutrient export and in my opinion a tank or a sump with mangroves just looks awesome.. also they provide very good habitat for all the little critters and clean up crew

    I have thought of that bud . They are , of what I have read great for netrient export and good as cleanup and maint. Goes but the problem is where to find it legally ... Anybody know ?

    I know there were plenty in Maputo not more than a kilometer north from Costa de Sol. also think one of the sponsors might have as a friend of mine was about to buy some recently just that he found them to be a bit expensive. didn't know that they were illegal to collect in SA not sure also about Moz. may be do a sponsor request .. would be awesome to see a mangrove tank on MASA

    If you going the natural route I would stay away from any phosphate remover as this will skew parameters you are actually trying to control. Some form of carbon dosing can help as this would help with bacterial populations, but I would do this in a limiting fashion. Just my 2c opinion. ;)

    Cool . Thanks carlos . You say carbon dosing ... something like biocubes perhaps ?

    Yup. You don't want to remove all your nutrients via carbon dosing. So just use it to keep things in check when your natural systems are up and running.

    only calciferous algae i know of is halimeda, the rest should be fine.

    as for mangroves they deplete magnesium too and grow to slowly to be any help based on what i have seen people say.

    The other thing is the sand for the dsb . Last time I used sand collected below low water mark . Is there a better substrate for a dsb and what's the word on the mud everybody is mentioning

    halimeda is the one you dont want :) it consumes calcium

    i used Carib sea mud on my fuge nano

    hard to say, i used bio-balls and ceramic rings for biological and, the algae did the nutrient export, the mud was great for critters etc, and wasnt thick enough for a dsb.

    depending on the scale you are going.

    cheato is a great algae, and grape caulerpa

    Caulerpa is great. Of all the Caulerpa's grape is the quickest to go sexual, and you don't want this to happen. You can prevent this occurrence by keeping your lights on for 24 hours or trimming the grape Caulerpa on a weekly basis.
    Here is a great read about Caulerpa:
