I used a bag of Caribsea Floramax, Root Tabs, Flourish, Flourish Excel, DIY Co2
, cheap incandescent hood with 6500k 13w CFLs, and an Aquaclear 20. I do 25% weekly water changes and never vac the gravel.
I trade in my Cherries, CPD's, and Rabbit Snails in at the LFS
for credit, I've gotten probably half my corals in my reef tank off the stuff breeding in this tank.
For the DIY Co2
I use a Hawaiian Punch bottle and it lasts usually around 2 months, takes about 5 minutes to mix up a batch. Don't do the cheap paintball Co2
method, I had a bad experience and it's very dangerous.
