I'm restarting my 50gal after it got a bit neglected. The CO2 ran out about a month ago and with my new job and always having more important projects, the only tank maintanence I did was keeping the fish fed.
Some needle leaf Java fern, not a huge amount but maybe ~30 leaves or so
Crypt. wendtii red -or- Crypt. lutea
Petite nana, ~6" of rhizome
Oh, and if anybody has an extra Rhinox 5000 diffusor, I'll buy it. I forgot to clean mine before reusing it and apparently the disc was clogged, thus exploding inside the tank.
