I have a friend who is heavy into Rift Lake Cichlids, and some of his tanks
are maintained at 9.0.  He uses coral in the substrate and a Mardel additive.
His water is at 270 ppm of general hardness.

I have Always been an Amazon kind of guy and so stick to soft, low pH tanks.
I have, in my early days had Angels that developed red streaks on the base of
the dorsal fins.  I was advised this was doe to bad water maintenance and I
needed to get my ammonia concentrations down.  I followed the standard
procedures of water changes and Ammo-carb, and the problem went away.  Ammonia
test kits tell me when I need to get dedicated about water changes.  Sick and
dying fish tell me when I have neglected to take ammonia readings, or have
ignored the warnings I received from them.

I haven't had ammonia related problems in a long time because I now use plants
in my tanks and do my changes faithfully.  Ammonia bit me hard for a while,
but eventually I figured out the magazines weren't talking about water quality
just to fill the text area of the pages.

If you decide that ammonia can't be a problem, you are going to ignore the
basics, because ammonia problems are basic.  That's why you have a biological
basis to your filter, whether canister, UGF, box, or power filter.  The
reduction of ammonia is critical to the survival of your fish.  If you don't
believe me, crowd a tank and turn off the filters.
