Setting pump to run for 10 minutes every half hour

[mgpro]

Hi,
I want to run the circulation pump in my Calcium reactor to run for 10 minutes every half an hour. The timer functions are limited to 8 settings each, and the dosing pump functions are limited to 24. Is there a way to do this?
thanks

do you need both current pump groups?

if not - use one group for a 10 minutes ebb/tide-cycle use function "current pump x" for switching the pump

Thanks again!
