Co2 -> excel only
My mini m setup depleted the co2 tank while I was on vacation. It's running a ray 2. I ordered a co2 refill online (I use the fluval kit but I'm modding it to accept pb tanks) and they won't be here until 5-8 business days. The plants aren't looking so hot either. So I was wondering if I dose the crap out of my tank with excellent and metricide, what kind of lighting is okay to avoid algae. I've never really worked with these chemicals without co2. Thanks!
Also, this is a plant only tank.
