Is reverse osmosis water system for home use and for fish tank the same?

Home use often has a tank for the water, but the RO is the same.

Many people often add a DI unit for their fish tank, but this is not used for home.

In addition, sometimes, the RO membrane people use for fish tank is one designed to remove more silicates and this is not needed at home.

Having said all that, the home RO water is fine for fish tanks!
