So then YOU don’t use it as an educational tool. Many folks do, though. It may not be the primary function, but it’s a secondary benefit. I have personally gotten much educational value from mine, learning about marine biology, microbiology, and water chemistry. And if it makes even one visitor to my home more interested in ocean preservation I think it has proven its value. I’ve got family who went home and watched Chasing Coral on Netflix after admiring my tank and learning from me how the world’s coral reefs are in danger.You are missing the my point. Home schooling is educational of course but you are not keeping a reef for home schooling are you? I am not and while my 5 years old can tell the name of most of the corals and fish in there I don’t see it more educational than having a hamster. You can guess my preference
