Heh... I only suggested it because the quartz kit has a bit of a design flaw; the stainless rings with o-rings that hold the glass are just a smidgen too wide, which causes a slight problem with filling, though it's possible with a syringe, and a huge problem with draining, which so far I've found pretty much impossible without wasting whatever is left in the tank. Of course the smallest needles I have are 18ga; possibly a 20ga or even smaller needle could pass by the tank's rings to actually get into the tank, so it could be drained via syringe, but I know that an 18ga needle won't pass those rings, the space is too small. I suppose if you blocked the top end, you could get the bottom of it off without wasting what's left in the tank, or least not wasting all of it.
