Is it ok to do small water change during 7 day treatment?

I’d recommend no water changes till treatment period has finished.

Can you this in a pond?

The instructions say for all ornamental fish only and the dosage is for aquariums, so not sure about ponds.

Will i need to take anything out of my filter?

I didn’t take anything out of the filter, just worked out how much treatment to use, it worked well fish were fine after a while.
