If you find the red ones let me know where, please
the red ones have a flat surface the jet hits before fanning out, all of the others I have found do not,, and make a fan shaped cone instead of a flat spray.
The blue one is a 180 degree

now my one concern is over heating the solution by running the pump 24/7 as its a eco 185gph and might get warm,so if it does can I run it intermitantly?? 1 min on/5 min off
