Do you just put the test tubes in the water or do you use something else to suck up the water and put it into the tubes???
I have been dipping my risned out test tubes in the tank. BUT I hate doing it that way. What if I have lotion on my hands, what if there are chemical residues in the tubes.
Anyone have problems?
is there such a tool that will suck up the water from the tank and let me drip it into the tubes (like a small nose bulb - or should I just go buy a nose bulb???)
Thanks
