    Hi everyone,

    I'm in the planning stages of my next scape and I have a question with regards to the substrate.

    I'm going to have a bright sand foreground and I'll be using ADA Amazonia in the back but I won't be completely covering the back with plants (I'm after a Vallis nana curtain effect 3 t0 2) so some of the substrate will be left bear.

    What it be Ok to sprinkle black sand over the Amazonia so the shrimp when added won't disrupt the aquasoil and leach ammonia? Sorry if this is a bit of a stupid question I was just wondering incase the sand effected the soil in any way.

    Thanks in advance

    Hi Mark

    It shouldn't be an issue using sand on top of Aqua Soil, but eventually it will become buried beneath it, as the grains of sand are smaller and denser than Aqua Soil.

    IME shrimp don't cause clouding with Aqua Soil Amazonia.

    Valisneria nana is a real sprinter :)
    i have this on my large tank but every week i need to fight with it. will be super dense and sending all ower its roots.
    as a tip i would consider vivipara probably less trouble with it.

    Thanks George, probably won't bother with the sand then.

    You've got me a bit weary about the Vallis now Viktor :?

    A great example what Nana can do on the TGM ADA demo tank:

    very nice plant but really grow dense and send root everywhere.
    for me this taken 7 weeks to be super dense, and that's the point when Nana is too much, other plants not pops out really from the layout.

    Cyperus helferi is a popular alternative that's easier to mangage, and gives a similar effect.

    It can attract algae in less than favourable conditions, especially as it adapts to submerged growth.

    Thanks Viktor, I see what you mean, looks great but very dense very quick and mines only a 60cm!

    Yeah I love the look of Cyperus helferi George but I'll be using liquid carbon only, do you think it'll be OK still? The substrate will be the same as my Iwagumi (Serenity Peak), I still have loads of the additives left (aquasoil, powersand special, tourmaline bc, penac P and W)

    Cheers

    I've seen this scape before very nice. It's a lovely plant and It'll look great as a backdrop although the care of the plant marked as DIFFICULT on the Tropica website scares me a little :? ....cheers George!
