Have you guys ever tried to childproof your tanks?
I can tell one (of many) curious little story of how my little cousin, 6yr old at the time, was at my house. He sneaked out of sight for two minutes and I found him watching my tank as a million flakes go through the water like snowflakes.
He managed to CLIMB the tank stand and dump the entire flakes can in my tank!
I have managed to keep him away from it ever since, but I was wondering what if one of these days... so have any of you somehow put a lock on your lid, reinforced your stand, etc. to successfully keep children from wreaking havoc on your aquarium biology?
