Dumb question alert.

Which are better, the 3's or the 4's? Any noise/size issues, etc?

Thinking of getting a couple for my 75, yet another example of breaking my own rule about buying everything twice due to inadequate research.
 
Or...you could test it and let me know if I should buy one. :grinyes:

HAH! IF I do that and it goes well then I will end up paying way to much at my LFG for 2 extra nanos! If I do it before you I will let you know! I got my 2nd overflow in earlier so I will be setting that up tonight. Doubling my return should do me some justice. I might even have enough flow in the sump/refug to still the nano!

I have 2 4's. 1 on each end. The only problem I have is aligning them just pefect and not messing up the sand bed. There is no noise/size issues with the 4's at all (granted they are rather large). I have almost convinced myself I should have gone with 2 3's so that it would be easier to control. Either way you are going to be happy.
 
Just a FYI :

I got a nano, and while they put out less then the #1 they are great. But they don't have the aiming ability as the #1's, since they use a much cheaper type of joint on the nanos..

But it is great for sticking in small places.. And it's a little more directional then the others in the line.. I'd a good purchase if you can find one for a good price..
