Here you go:
The first 3 sentences have nothing to do with the situation and as such do not help. The last sentence is simply bad advice.
Fish are already stressed from being at a higher temp than normal. Your advice to do a daily 50% wc with temp lower than the regular temperature a few days in a row would increase the yoyoing of the unusualy higher daily temp for already stressed fish. It is bad advice for that situation.
Guess we will disagree then. It is solid and practical advice.
