so i bought a tank and stand upgrade , from my 10 gallon to 29. got a used light on craigslist with teh tank and everything, one of the parts for the lights doesnt work and the other light does. so my roommate has another light ballast that he does not use. i decide to change his bulbs. due to a crack salt has infested the inside and i guess i broke it trying to switch in my new bulbs, does anyone have any suggestions of where i can get cheap prices on ballasts. needless to say im ready to explode after this episode.
