Hi, I'm really new to fish tanks ; I started in Sept 2012 because my daughter asked for a Betta Splendens. After setting "her" tank, I started "mine". I'm a big fan aquascaping and "natural" tanks ; I don't want to add "chemical" product nor technical filter, etc... So this is my second low-tech tank : about 20L ; 50x17x25cm. Ground using "Sable de Loire" and white Quartz, pieces of wood called "Asia" on the website I ordered, Ohko stone and "easy" plants : Vesicularia Ferriei Weeping Moss, Eleocharis sp Mini, Vallisneria Americana Mini Twister. Light is provided during 10H per day from a LED bar (Lumivie SJ). First, I did change 50% of water every week. Then slowly decreased as the water remained more and more "healthy". To add nutriments and CO2, I have a bunch of Daphnia pulex, Physa, Planorbella and Asellus aquaticus. I also added Neocaridina heteropoda 2 weeks ago. So far, it runs pretty well. Here's a quick sum'up of the first days of the beast Day #1 : White, grey and brown. Day #2 : A touch of green. Day #30 : Needs of bit of triming. So, what you think?
