Fish Tank Hard Water Spots

what is the best way or product to take the hard water ring off of your fish tank or clean the glass ?

i’ve tried the little sponge thing but it still leaves like water spots….anything else that will make it crystal clear? that wont hurt my fish & turttle?!

you can actually buy a scraper from your aquatic shop or pet shop that will do the job it wont scratch the glass and is made for that purpose!
