10x would normally be considered high, but is suitable for certain
applications where there is a high degree of mechanical filtration needed
(strong pickup power), or there are a lot of obstacles in the tank (mbuna
in rockwork). For biological filtration, you do not need high exchanges,
x2-x3 is sufficient. This might help you.

Hmmmm.... I just noticed the Whisper is rated for 330gph ( adequate for
30 to 60g tanks) at my LFS. I read somewhere that a flter should turn
the water over 10x the tank capacity. Could be wrong, would not be the
1st time LOL ;-)

A reading of GH of 150 is not considered hard, over 200 would be. I am
curious as to your KH reading. Also do you currently treat your water,
ie water softner? I am also a bit leary of a NO3 reading of zero.
Under
10ppm yes, or even 5ppm, but I have never had a reading of zero,
myself.
You mention your water chemistry. Do you add chemicals for PH ect?

With the amount of fish currently in you tank. I would recommend
weekly
water changes. Overfeeding, is only one source of extra ammonia in the
water, all fish generate ammonia by gill action, urine and fish waste.
Your whisper 60 rates at 240gph, if memory serves me correct, which is
just a bit weak for your current tank, 300gph would be better.
