lol, do you have lr and how old is your tank, you may wind up with some, and once you do, you wont have any problems either, it will more than likely get to the point of you needing toharvest it too, in fact, it often gets to be a bit of a nuance, by overtaking it, i actually dont reccommmend adding much to the tank because of this and think you should think twice before really worrying about it too much, because it will do more than get the tank started
