I can't stand cartos with filler, but I love carto tanks. I use the Ravens, still on the first 3 I opened 2 months ago, they can be cleaned and dry-burned. Also the cartos from Ikenvape have the reputaton of being the best filler cartos. Seems a shame to pitch your tanks, these might be worth a try...

Well that certainly is intriguing! Hmmm. Guess I'm gonna order one of those too. Since I'm in the mood to try something different, that certainly is worth a shot. Thanks
