> If tank fails, you are liable for water damages and home insurance DOES NOT cover that.

Whether an aquarium is covered by home/renters insurance is specific to the policy and aquarium size, not consistent enough to make statements like this. This aquaponics system is essentially a planter on top of a low stock aquarium.

I will say that the shelf supporting the aquarium seems inadequate to the job, increasing the risk.

Structural support in the floor? There are people that weigh more than this. It’s only 20 gallons

This is covered in the post (emphasis mine):

> With similar concerns in mind, we also decided to limit the tank size to 20 gallons, as the grow-bed above also contains an additional ~10 gallons of water. Since a gallon of fresh water weighs roughly 8.34lbs, we estimate this puts the entire weight of the system’s water somewhere between 170 and 250lbs. Considering the weight threshold of the industrial shelving, and given that we live on a high floor in our building, we decided to constrain the system to this size to minimize the flooding risk.

> home insurance DOES NOT cover that

Citation needed. Very bold sweeping claim

And people are wondering why being landlords is often such a bad investment.

Imagine the lawsuit if you rent out an apartment that you own, and your „very intelligent“ tenant produces water leak damages, in a nyc high rise with potentially ALL owners underneath you affected.
