The is the second thread about this, the other started a few days ago. See post #170 onwards.
Did your dad drag you onto the forum to back him up when he's losing arguments? Are you a little loopy like your dad, or normal like the rest of us crazy people? :) @TheLavenderBadger, don't mind @Colin_T he's always a little loopy 🤣🤣

Get a portable room air conditioner, your gonna need it in the future.
Keep doors, windows and curtains shut during the day.
Open house up at night to let cool air in.
Turn off any electrical appliances you don't need on, including tank lights, TV, computer, anything but the fridge, fan and filter.
If you get too hot, stand under a cold shower with your clothes on and then sit in front of a fan. As the water evaporates it will cool you off.
If you have to go outside in that heat, put a long sleeve shirt on and stand under the shower to get soaking wet. Wet your hair as well. Then go outside. The wet clothing will help keep you cooler for longer.
Wear a broad rim hat outside or use an umbrella to keep the sun off you.
Avoid going outside between 10am and 4pm.
---------------------
With the fish tanks, Byron covered most of it. Do a water change and gravel clean the day before the heat is due so the water and aquarium is cleaner. Clean the filter too.
Increase aeration to maximise the oxygen level in the water.
Remove coverglass if it's safe to do so.
Keep tank lights off during the main part of the heat.
If the water hits 30C, it's fine. My tanks would sit on 30C+ all summer and the fish ate normally and did their thing. Lots of aeration is the main thing to keep oxygen levels up.
---------------------
Most water companies will add more chlorine or chloramine if there is a heat wave. If you do water changes during and for a week after the heat wave, make sure you dechlorinate the water before adding it to the tank. And use a double dose just to be safe.
You should also vigorously aerate any new water for at least 5 (preferably 30) minutes before adding it to the aquarium. This will give the dechlorinator enough time to come into contact with all the chlorine/ chloramine molecules in the water and neutralise them.
