Carto tank issues, flooding carto?

[dwarfcat]

The first time I fill up the carto and tank everything works great. However I run into issues flooding the carto when refilling the tank. I think im doing it right. I remove the top cap, push the carto down and put the juice in the tank. When I push the top cap back on the carto floods and juice comes out the bottom connector hole and out the top of the carto. By the time im done blowing the juice out of the flooded carto my 6ml tank is almost half empty. Was wondering what I could be doing wrong.

There is no need to remove top cap, doing so will flood the carto when reinstalled.
By blowing into the carto (holes covered by liquid) you're over pressurizing the tank which causes more flooding.
If you need to clear a flooded carto tank hold it upside down so the liquid level is below the holes in the carto, then blow to clear.
Leave it upside down for a minute so the pressure can escape / equalize.

I fill from the bottom and don't run into this problem.

To refill a carto tank you pull the carto partially out and fill from the top. Get a refill tool like the Slap Yo Mama to save your o-rings. If you remove the top cap you will flood the carto putting the cap back on every time. There is other tank tools out there, IBTanked sells one for much less. It's the one I use, but I want to get the Slap Yo Mama for swapping cartos.

On my J tank I do not remove the top cap, just push the carto down into tank & push it over to one side so I can get the fill bottle in there. Fill it up to near top of carto, about 3/4 full & push carto back up. No flooding
