My main objection was CHEAP FISH, this phrase would imply that you would not care if they die during cycling? IF you are strapped for cash, why rush? Impulsiveness is one of my faults, i have been making mistakes for years and will probably continue. This is why i joined this forum. Why do you not try to save some money before you make the change to marine? Then, when you have the money, you can purchase the LR (LIVE ROCK) you need. Patience is a virtue, so the time you spend saving can be put to good use researching, which in the end will result in a better tank with happier inhabitants!
good luck.
