It's currently low tech, but might go CO2 depending on how the plants adapt. How do you attach moss to dw?
That's got to the most costliest tank...+price tag of a house, lol
Sorry I missed this Zenche,
To attach moss to driftwood you can use fishing line or cotton string (which is what I use) and wrap it around the moss to the wood then tie it off to secure it.
I've had the best luck with separating individual fronds of the moss and laying them facing the same direction on the wood with a slight overlap, making sure I never just pile it on. I prefer the cotton string since it'll deteriorate after a period of time and by then the moss will have attached itself to the wood. [I tried just throwing some on my wood before and tying it but ran into issues with it just not looking good and not growing how I wanted it to, since then I separate it and do it in the above way with success]
I've also used superglue to attach moss before with success (with flame moss). You can see the glue till the moss grows over it though.
I've also known people to cram some moss into the cracks of driftwood and left it alone and had it grow by itself, just have to make sure there isnt too much flow that will knock it out of the crevices.
Another option, one that I plan on using on a couple of pieces of wood I have soaking right now is to drill some holes in it and stuff some Mini Pellia I have into the holes and let it grow out that way.
The tank is looking great. Glad you got some CO2. How are you getting the gas to the tank without a regulator? I dont see how you could given the high PSI coming out of the CO2 tank itself. Are you referring to a needle valve to adjust the CO2 rate?
Not sure if you are able to use Ebay or something similar in China but there are alot of good regulators online. You can build your own for a reasonable price at least here in the states. You could also try to get a basic paintball regulator and get the Adapter for a regular CO2 tank to adjust the pressure. Needle valvles are available online as well. ADA has CO2 systems as well but I havent used them. I've only used their tubing and diffusers.
