How much to use for 200l?

Not sure, however I seem to remember it worked out at 20ml for 100l so that would make it 40ml. It tells you on the label I'm sure

Can one use api stress coat with purigen?

Yes, I use purigen bags in my canister and use stress coat when doing water changes

Where it says "5ml per 40L of water" does it mean per 40L putting in a per 40L that's already in the tank? How much should I put in a 10L bucket?

******20 drops for 10litre******to remove chlorine and chloramines...#### To replace slime coat and repair damaged tissue 10ml per 40litre of water###...So on a water exchange use *******when tank is full use #### I do hope that makes sense. But the instructions are clear on the Bottle.It is an excellent product. Good Luck.

How long do have to leave the makeup water in a bucket before I can use it.

Hi. You can use treated water straight away. I get freshwater ready first then empty out old tank water then put in the new treated water back into the tank. No harm is done to your fish i have always done it this way. And all my fish are healthy n happy swimming around. Hope this helps. 🐟🐠😄
