Is that a new flavor for you? Hope you like it as much as I.I use Xl cartos in all of my standard size tanks.They do stick out about a half an inch above the endcaps but they make refilling SOOOOOO much easier if you have a tank with thick pyrex walls.
All I do to refill is pop the top cap off by rocking it gently with my thumbs and then slide it up the carto until theres enough room to pour right from the bottle. Unscrewing the tank and blowing through it gets rid of any air bubbles. A slim drip tip the same diameter as the carto helps with this as well.
Just be warned that tanks with thinner glass/plastic and/or thinner endcaps can crack from this method.I actually wouldnt recommend doing it with anything but a Phiniac.
Thats Kona Velvet Milkshake beside it too Bad![]()
I cringe

I guess it just shows that there is no one way that is correct or an only way. If your method works for you, keep at it.
