Few day ago, I decided to go to pressurized CO2 route. I ordered a regulator from Orlando, and it came the next week. The regulator is solid and work so well, my plant pearling so crazy, which i never seen in my DIY CO2 setup.
Just want to share my happiness with u guys

Minor update for the tank
I will have riccia, HM, and dwarf hairgrass ship to me next week. Cant wait to do another scraping.
