I have decided to start a 2nd (new) tank. Thinking 75 gallons or so? My very, very old 46 gal bow front worries me. So, before it blows- I can take my time in getting the replacement up and running. Can any of you very nice experienced people recommend any particular products. I have chosen the spot. ( 5' in length). My current bow front is 21 inches tall. I am samll and can NOT reach the botton of the tank to clean the glass! I have had to use stool -what a pain! Hoping to find a new tank that is longer / and not as tall. Thanks
