    Ive had a small 30l system going for ages (just over 2 years) and its never realy had a plan, or more correctly ive never put the symbiotic shrimp and goby combination plus zoas i originally intended it for. Instead I had some red macro algae come in on some LR which i wanted to save and i place a whack of LR (for its size) with some macro algaes etc and just left it.

    Ive wanted to see how well i could maintain a tank with primarily biological filtration and thus this tank is just run on macro algae, LR and a good sand bed. I had a skimmer but the pumps blown and i havent replaced it again. A key aspect to the tank though is good water movement and thus I put a small tunze power head in, and that keeps water movement through and around the LR going well, although algae does choke it every now and again.
    I do very little to look after the tank. I feed the fish fairly heavily (nutrient for algae growth mainly) and do 20% water change every two weeks.

    Its got a 150W MH over the tank and a heater.


    enough talk, here are a few pics:
    LS are three fish (an clown and two azures damsels, all of which have been given to be looked after from others tanks and the owners never came to collect them again. I'll most likley put the damsels into my larger tanks soon, although they do very well in there for now:)
    Lots of different algaes, two red macro's, three green macro's, bryopsis, GHA, bubble algae and a number of others I dont know.
    Lots of micro stars and a few hermits as CUC
    A few aptasia
    A few asteria stars.
    A few things I dont know:)

    Very cool!

    I have a small 40cm x 20cm tank in the garage and I have an extra Vertex Illumilux 600 lying around, no other equipment though. Perhaps I should just get an internal filter to act also as flow with frequent water changes.

    The large amount of macro algae seems to be doing the trick for you on it's own?

    Do you just manually top-up with RO every day?

    to be honest I am very lazy with this tank. I do very little other than walk past it and sit at my desk. So the water level drops quite alot over a week and then i add new RO. I have been meaning to put in an ATU (i have all the parts) but i never get round to doing it. The water fluctuation is probably the biggest difficulty this tank faces and I realy should sort something out.

    Just to note, the red macro algae is VERY slow growing and the different greens far quicker, so I cut those occasionally and drop them into my reef tank to be eaten, and if the tunze powerhead is choked with algae it get dropped in the main reef tank to be cleaned by the tangs, which appear to eat any type of algae, bryopsis included. I'll try get a pic of them picking off the bryopsis when i next place a piece of LR from this tank into the main tank, although I try NOT to switch the LR around between tanks too much as I dont want cyano in the nano (have it in the main tank) and I DEFINATLEY dont want bryopsis to get a root hold in the reef tank, even with the algae eating machines I have in there. Just not worth the risks.

    they are indeed, i had a spike in NO3 over summmer while i was away and they battled in the main tank so i transfered them over and since then they are doing very well in the nano so leaving them there for a while:)

    Love it when nature is running at a pace it's suppose to be. Imagine a tank without a skimmer? Have read somewhere it was possible, but I have now seen it with my own eyes. Excellent:thumbup:!

    @dallas will have a chuckle that this tank is currently running without a skimmer (i hear the irony myself:)) but to be clear its only running skimmerless due to me not being able to replace the pump in the tunze skimmer I have for the back compartment. The tank would run better with a skimmer in it of that I am sure, and if i change the bioload i will have to sort that out first.

    carlos, there have been some excelent skimmerless systems on masa in the past

    Is that the little nano that was to the left of the tank? (if you stand in front of your tank)

    Surely does look like the tank is happy, even without the ATU

    Very nice Crispin! I have a little Jebo 40L tank thats been sitting empty at my mother in laws place for some time now...you've inspired me to go and do something similar with that...minus the Damsels though! :thumbup:
