i want to get a ro/di unit, but man there expensive i was wondering which one should i get. i saw some on ebay but not sure if there good, never used one either, but livestock is doing ok 11months lol
is there really a difference in quality? coz i am thinkin bout buying one too, i've been using filtered water all this time. whats the difference between a brandname one like coralife or one from ebay? thanks
