For the safety of your frog's health you will need to change the water daily. Any urine from the frogs will be in the water and the amonia levels can become deadly. These frogs urinate A LOT! I know this seems like a lot of work, but it must be done. You could just give them a shallow water dish rather than a pond area.

Also be careful of moss. If they accidentally ingest some while trying to catch their food it can cause an impaction(intestinal blockage) which can lead to a prolapse and death.

I agree with everything you say

I usually put a water dish, the pond in summer only
Also be careful of moss. If they accidentally ingest some while trying to catch their food it can cause an impaction(intestinal blockage) which can lead to a prolapse and death.
I feed the frogs out on a large plate
