Pump on or off?

[hydrofiner]

I curently have a home made undercurrent system with 5 3gal. pots and 1 18gal reservoier. The girls are doing fine just started bloom phase. My question is now that i'm 12 on 12 off do I keep my pump running while my lights are off? I have been, I hope i'm not messing up. They seem to be doing just real good. PH steady 5.3 slowly increasing to about 5.7 over 2 1/2 days. Just wanted to know about my pump running. Thanks.

bubblers and pumps should probably never get turned off as they regulate the even distribution of ph, nutrients, water temps and o2.

Turning pumps on and off regular shortens life expand of equipment... keep it running 24/7 for best results
