I need some help writing the codes for my Tunze pumps. I have 2 Tunze pumps and the Apex. I understand how to write the codes to get the pumps to oscillate (OSC), but I do not like that way (don't ask me why). I want to have something more like the reef crest mode that the Vortechs have...ramping up and down in a somewhat random pattern. Any input would be great.
