Boge cartos in a glass tank - does it matter if they have one punch or two?

I use a Supco Bullet Piercing Valve BPV31

Which ran I think $5 on Amazon.

Minimal deformation of the carto as it supports it all the way around while it is being punched.

Myrany! Good to see you, hope things are going great for you. Still loving the Banana Cream, the Chocolate is good too, but I like the Banana more. The pyrex DCT is performing well, thanks for the tip. I hope your sister is doing well.

You could always wait until you see how well the cartos work before getting a puncher.

Ocelot, I just noticed the asterisk on your avatar, the star beside your status I noticed a few days ago.

Oh, to the OP, both of these ladies make a good point. The BPV doesn't deform the carto much at all, and you may want to wait to see if you even need one.

My darling Ocelot - that would be way too logical
