I started this 20 gallon natural in February 2015. It's my second planted tank following my 10 gallon. Many thanks goes out to you APC members for helping me along. I couldn't have done it with out you! Noteworthy is that I stocked this tank from a local LFS and it bloomed some nasty BBA. I read a post from Michael and consequently added a second HOB, have kept my NO3 <10ppm, and trimmed the plants some. It's all but gone now! Yea! I also use pure RO water and buffer it for GH & KH. It's not a high tech show tank, but I'm very pleased with how it's evolving.
