Thanks for sharing.
I am trying to do the same with my altum tank.
I got a pool timer from amazon, but it did not come with any cord.
So, where do you get the power cord?
Another question is: did you use the box coming with the timer and just bending the edge to firm the bottom round table?
Thanks.
you can purchase an appropriately sized cord at home depot
yes, just modify the utility box that came with the timer
good luck!
