This isn't really something we monitor to be honest, so I don't have a good number for you. If he's not drinking much water or eating very wet food, he likely is getting slowly dehydrated if he's getting 200ml water subcutaneous and urinating that 200ml out, since he will lose water through his feces, breathing, skin, etc. I'd recommend letting his vet know what you're seeing, checking in on his kidney values, and consider increasing his fluid levels slightly. However, I wouldn't do this without guidance from his vet, because there are other issues he could have at the same time that would require taking a more moderated approach to the fluid amounts.
