Twist your own mate. I'm not clued up with the squape but 2 strands of 0.32 kanthal works well for me in tanks. You either use a drill to twist or what I have done is get a reasonable length of wire (maybe 1 metre), thread it through the handle of a mug, put the 2 ends together and hold them with some pliers, let the mug hang and then keep spinning it until one of the ends of the wire snaps (either the plier end or mug end). Hope that makes sense
