what water to buy ?

ok whatever, i will "chill" but i will say this again, watch what you say and more importantly how you say it, like i said again, people here are just trying to help...unless they say something like poke your leather to wake him up, thats just silly ;D. just out of curiosity, what size tank do you have, and do you have any pictures? the size is a good indicator as to whether it would be better to buy an RO/DI unit or go to the grociery store like i do. you should post some pics and your inhabitants to give poeple a look at what you have, good luck and hope to see some pics
