How do you protect your fish tank from toxic fumes?

I had a client who lost their entire tank of discus to toxic when they had someone re-do their wooden floors. How could this have been prevented?

You could move your entire tank somewhere else? Re-home them? What if it’s not possible?

What I suggest (but wonder if it’d work) is to do the following:

– stop feeding fishes for 2-3 days prior tithe event to decrease the tanks’ oxygen demand.

– turn off the aerator to prevent the toxic fumes from being pumped into the tank.

– heavily plant the tank and turn the lights on for the duration to ensure oxygen supply by the plants.

– keep the filter running and also run charcoal through the system to adsorb harmful chemicals.

– seal the top of the tank with several layers of glad wrap and tape all the edges to ensure there are no gaps.

– cross your fingers that it’ll all work out well.

Any more precautionary measures you can add would be most appreciated.
