That's what we're here for.
change the actinics and search the for sale adds on fish forums or craiglist for a used co2 setup..they are always someone selling and you can get a good deal. the paintball thingy is a hassle better get a 5lb tank so you dont have to worry for awhile
While I would avoid a paintball tank on anything 40g or more; a paintball co2 tank will last a long long time on a 20g tank.
That depends on how high you run it. Regardless, if a paintball tank lasts a long time, a 5# will last longer.
Also, I know there is an adapter that connects a paintball tank to a standard regulator, but I don't know if you can easily convert a standard tank to a paintball regulator if you wanted to upsize. Does anyone know if you can do that?
I agree with replacing the actinic with a 6500K.
Actinics tend to make planted tanks look bad/cheesy. It goes against the whole 'natural' theme that most people try to accomplish.
