The new technique on feeding and caring for your aquarium fish

My first aquarium tank I bought several years ago was 150 gallon tank in which I learned a lot uncaring maintaining and feeding the fish one thing that I did notice is that while you're feeding them the wasted food that sits up on top and floats around I seen at one time a fish floating upside down food that is left over and it is not consumed up causes bad water quality consumed up causes bad water quality I have come up with a way to feed maintain test and change your water all in one.
