One thing i just realized,in that link someone says the shorter top cap wont work,but the taller one will.I'm not sure on that,because if you look at the listings for the short and standard ones,the short one has an o-ring to seal the chimney,which is what the orchid has,the taller standard cap looks like it is for a threaded chimney.Also i just realized that they say the reason the shorter one wont work is because the chimney sits to high for the drip tip,when i put that nano on the other day,the chimney stuck way up there,and my drip tip slid right over it.There are probably some tips that wont fit over it,but mine is a wide bore tip and fit just fine.Instead of ordering both caps,i think i am going to order the small cap,mainly because i like that drip tip that comes with it haha,plus that tip looks like a wide bore,so it should slide over the chimney just fine.
Don't worry,i didn't forget about ya,i'm working hard to finish this tank so i can do that nano fill test,it's taking longer than expected though,because i keep having to set it down and regain my composure due to the way this thing hits,plus it's wicked with rayon.I really need to lower my nic level now haha.
