This stuff can be confusing. I think I got it though, and if I have really hard tap water, a lid could actually help lower pH, so all in all probably not a
bad investment for a newbie.
I think I am sold on the 40 gal breeder tank though. I laid out a bunch of tank footprint cutouts last night at work (yeah I had some free time after the supervisor left
) and it really does seem like the most bang for buck type thing to me. I'm a hands on type person though, and will have to see an actual tank on a stand to really get a feel for it, but for now, that is what I am thinking. However, I am a girl and reserve the right to change my mind!
