adding water to aquarium

Question
OK I am really new to the aquarium world.  we just purchased a house with a built in fish tank (freshwater).  The water level is getting low- what do I need to do?  I know that the water needs to be changed periodically also- any advice?

Hi Stephanie,
Thank you for your letter. I have posted a page of easy wholistic aquarium care instructions:

Please print it out for future reference. Everything you need is on that page.
Write back if you want to discuss further.
