I havent wasted one penny. knowledge is priceless.
now if you want to ask how much money I have "lost" good god, thinking about it would make me sick. so i am just going to suffice and say i have a lot of spare crap that I wouldnt even sell to someone who didnt know better even if I hated them, and no one has ever had a 100% success rate, if they say they have they either havent been in the hobby long enough to kill something (empty tank) or they're lying.
