That's a shame that they're 14mm. I'm really hoping to find the smallest one because I don't want to try and rig them so that they stay on my glass pipes. I would imagine that a good tight fit is important on these, I have a hard enough time keeping the sponge filters over them!Ugg....I bought one size too big from ShrimpLab....I think mine is 14mm and I have two brand new...
I'm in Issaquah if you can make a 14mm work for you...
Thanks but I am specifically looking for the ones that The Shrimp Lab sells because of the tight rubber fitting at the top. I have even seen some on Aquabid but I don't think they look as nice.
the ebay ones are also pretty diy looking as well..There is a seller in Asia on Ebay (probably the exact same ones but it takes several weeks to get them) and also someone that makes their own on Aquabid.
