Do wenot need the second pump for overflow pool with wet wall effect

[Anfisa]

Good day and I will appreciate your help very much!!.
Could you advise us whether we need a separate circulation pump for overflow pool.
The decorative pool, with pool volume just 3 cubic meter, and glass wall and wet glass waterfall effect on this glass wall.
The weir rate is apprx 12 cubic meter per hour.
We plan one circulation pump with sand filter.
The customer wants this wet glass waterfall effect during all day hours, so apprx. 9-10 hours a day. And we do not want to filter the water all these hours continuesly. But if we switch off filter circulation pump , as using one pump, the waterfall effect will dissappear.
But whether it is good also to add separate pump running independently, no idea how to plumb it..
What should we do in this situation?
Pls help.

A,

So what is the problem with filtering the water for 9 or 10 hours per day??? Sorry, I just don't understand the problem..

Thanks,

Jim R.

Ok Jim,
Thanks for reply! thought the volume of pool too small, will be filtered for many cycles.

There is never too much filtering of pool water. If the pool water is clean then running it through the filter many times has no effect on the filter. And if the pool water has contaminants in it then it is good to filter it out.
