this tank with the current substrate has been up for about 3 months, it will need to be broken down in about 1.5-2yrs from now. the substrate is Aquasoil 'amazonia', sold by Aqua Design Amano (ADA). this is the BEST aquarium substrate in the world. unless you have tried the rest, its hard to understand why this stuff is soo much better, but it is.
aqua forest aquarium
is the website for the flagship store, and foremost distributor of the ADA line of products in the US. The store opened 2 years ago in San Francisco, and is run by my friends Steven and George Lo. The store is also conveniently only blocks from my house! (which is good for me and very bad for my wallet). all the products made by ADA are very expensive, they are not designed for your average aquarium keeper on a budget. this stuff is like the Ferrari of aquarium equipment, no expense is spared. the cost of the merchandise reflects the attention to form and function that has been put into every piece sold by ADA. the very best stuff period, nothing even comes close.
after having said that, i would add it might not be the best soil for your first planted tank... aquasoil works best in conjunction with a few pieces of fairly $$$ equipment... if you don't use all the required pieces, it probably isn't worth doing at all.
aquarium keeping is a daily challenge, and requires constant! maintenance. if this sounds like a lot of work, its cause it is, and a whole lot more.
but yeah... Takashi Amano is the dopest aquascaper ive ever met, an incredibly savvy business man, an absolute visionary, and a very cool guy to boot.
