I always have a hard time finding these so I thought I'd throw them up here for everyone. All of these are from the Betta4all forum, I don't know anywhere else to find them but if someone has like an IBC handbook or something I'd appreciate them going over these and double checking that they're correct. (Though I'm actually very confident in they're accuracy.) EDIT: Study break is pretty much up I'll be back in a few hours to continue. Please let me know if I should or not. Thank-you.
