Right now I got a 29g..I have one finnex stingray already on it..it seems like it does an alright pretty good job but I was wondering is it worth it to get another? Or should I go with a cheap beamswork? I found a couple for 25 to 30 bucks..but it seems a lot wider and thicker...then my super slim stingray..is it worth it? Or is it a waste of money? Any thoughts?? Not really wanting to buy a 24/7 or Ray 2 since I rather buy one of those when I get a bigger tank down the road...
