Yeah man, spend all your money setting one tank up correctly instead of spreading it out into 10 different tanks. I can't barely keep up with the cost of keeping one tank, let alone four or five tanks like you have. The first time that I quit last summer, I got tired of the hassle it take totopping water off on four or five tanks. I sold off my RO/DI and had to go to the store to buy RO water. You're a young guy, you still have the world to travel (but don't travel right now) and many ladies to conquer. Don't let all those tanks make you into their slave. Concentrate on one tank at a time, and do it well. B4 I buy my stuff, I usually research it out thoroughly on my own. Don't just rely on the word of the one fish store owner.
