    Anyone doing it in the style of Diana Walstad or close to it? Care to share?
    How about those filter-less ones? Or simple tanks with plants growing well without much intervention.

    Wow - this is beautiful! So matured already. How long have you kept it?
    You got some substrate in there since you planted Hair Grass? What did you use?
    Do you do water change?

    Hi juggler, this tank in office for like almost 1 year + liao. The last water change was 9 months back. Typically only add <5% water every Monday due to evaporation. Nothing else needed.

    Hairgrass ah? I juz planted a few strands inside the ADA soil and it took off by itself. One of the easiest plant to grow Of cos, initially 2 months had some DIY CO2 to kick start. After that, took it out and just left it like this.

    - water change frequency and how much
    - tank dimension
    - lighting W/L and how long each day
    - Is the moss "Taiwan moss" ?

    when i started, i was blur like a shrimp ... so juz took a few clumps and plant at 5 spots ... first few months it was real slow ... then it went wild and gradually crept over the whole tank ...

    oh ya hirowen, i did use some DIY CO2 for the first 2 months or so to kick start the plant growth ... took it out after that due to plain laziness

    this was how it looked like long time ago

    Frankl speaking what is the purist way of Diana Walstad? Can anybody explain? Did anybody actually buy her book.

    I saw some people's tank planted according to her treatise and also gian of doing. If i am not wrong, he recommends just grow and leave it. No CO2, fertiliser and even Light (i think).
    Me also gian of doing. I bought a 6"x8"x8" tank filled with moss, using shrimps and ambient light. Hope can grow till look like Joe's

    actually DW do use light but also allow sunlight into the tank as well ... she does preach not using any fertiliser and CO2 ... let the critters provide these

    Hi,
    this is my 30L (40*25*30cm) Crystal Red shrimp tank:


    The set-up of this tank is only one week old on the picture but I used all the stuff and the water from an old tank, which was too small for all the shrimps after some months. It's a breeding tank for my CR shrimps, not a display tank.
    I use no substrate, just a 15W FL, 3 bubble filters (1 would be enough but the other 2 were left over and I didn't know what I should do with them, that's why I put them into the tank, too) and a heater, so that there is a water temperature of at least 21C. There are several Anubias sepcies, java fern on drift wood, java moss, European frog-bite Hydrocharis morsus-ranae, Willow moss Fontinalis antipyretica var. gigantea and star duckweek Lemna trisulca. The last three plant species are native species in my region and there are doing fine in this tank (because it's relativly cold with a water temperature of 21-23C). From time to time I introduce some liqiud fertiliser and I do a water change of 40-50% every second week. The CR shrimps are doing fine and show the best colours I ever saw of them.

    regards

    Robert

    Hi Joe,

    Filtration: Nil
    CO2 injection: Nil

    Fertilisation: 1 drop trace once in a while.
