I have a 60x18x28 110 gallon tank that houses my eartheaters. So by design it has a lot of exposed sand and just some clumps of swords, as well as java fern and anubias. So nothing too special or complicated. I have the ability to crank the light to 3wpg if I want but have just been running 150w since setting it up.
The plants are doing OK, with slow growth and little algae. It has been 2 months but I only just started occasionally dosing ferts (2x a week the EI dose for a 40-60g tank) because I noticed an anubias yellowing. I had some swords die off but that was due to the light burning them... Since pruning all that off the rest is looking fine. They seem to be doing better than when they were in my 55 with more light and roughly the same ferts (but no CO2).
A while back, before I set up the tank I bought a 20lb CO2 canister and a nice regulator/bubble counter/reactor setup. But I got distracted and never set it up, plus no matter how much I read here I'm always nervous that I'm going to screw something up and kill my fish.
I don't really plan to add any more plants (unless people have suggestions on a good way to hide more of the blue background with something simple that looks good) but I obviously wouldn't mind more growth... but the fish will always be the focus of the tank. If all I have are these basic plants, should I even bother setting up the CO2? Or should I just sell it and use excel instead?
