Thanks for the tip! Is it even possible to tell which way it goes back in otherwise? Also will the red gasket stay in while I clean it or should I remove that as well? Is it really that difficult to get back in place?
Which tank? Rev 4?
The glass on Boro tanks has a bevel on one side, that lets it slide to do its job.
The Rev3 glass is asymmetrical, so it's foolproof in design.
The Rev4 is symmetrical, so if you get it flipped over, it won't do its job very well, if at all.
Unless you have a very keen eye, I've heard it's almost impossible to tell which is the front or back...until you assemble it and it doesn't work.
As far as the gasket, I've had ZERO issues putting it back in.
Now, putting the Delrin tank gasket back in was a bit of a challenge, because of all the fiddly screws.
I typically just wash my tanks, and if the gasket pops out, I put it back in. Most of the time it doesn't pop out.
After a light scrubbing in warm soapy water, I let the tank soak in running warm water, so any soap left in/on the gasket will go away.
