Just wanted to plug these sterilizers for anyone looking for a smaller, budget-friendly UV sterilizer option that is also in-line instead of submersible. I got the 7w for 80 dollars on amazon and they take 7w phillips bulbs. Plus, the product is UL listed in the EU unlike most chinese-made UV units (main reason I bought this over other no-name brands). This unit has cleared up my dino problem in my 30c cube quite well.
