best time of day to change out my cartridge filters

[charsand]

Since health issues have slowed me down, I imagine it will take me a few hours to insert new cartridges in my filter. I am in the middle of a SLAM and need to change out the cartridges. I was wondering what time of day would be appropriate to lessen the effects of not having the pump running. In the past, I was able to accomplish the task in about an hour, now it might be 2 hours or longer.
Any suggestions are welcome.
Thanks

Whenever it is easiest for you. The water will not know much difference.

I know some members have a spare set of filters on stand by. That way you can quickly exchange out filters and then clean others at a time that is convenient.
