What is the best way to sterilize a tank?
My betta passed away 2 weeks ago and I want to get the tank , heater, thermometer and some glass containers also sterilized.
Several years ago I got some advice from another website to use bleach at one part for every 19 parts water (1:9 for glass) let sit for 30 min and then rinse, rinse, rinse until you cant smell the bleach, then fill tank and add 10-12 times the normal amount of dechloranator.
I did the above and one time it seamed to work good but then another time I couldnt compleatly rid the tank of the smell. The tanks I have are acrylic...I think. The bowed 2.5 gal kind of tanks. Also the heater suction cups and thermometer cups are rubber or silicone?
So is this good advice or is there a better way?
Thanks for your help!
