so what exactly is reverse osmosis water? is it just purified water?
What are the filters made of?
Answer The faucet mount, countertop, and undersink cartridges are made of carbon and an active agent to remove lead. The carbon and active agent are bound in a block form. The new 2 and 3 Stage filters for Faucet Mount units also have a sediment wrap around the carbon where larger particles are removed.

For a small aquarium, buying distilled water is more practical, or possibly collecting rainwater, if you don't have acid rain.Just check your hardness to start with, then dilute it w/distilled or rain water until you get ac acceptable mix. Distilled water contains no minerals, and is as soft as water ever is.
