I am running a 33 gallon tank with three goldfish (one red cap oranda & two
black moors). The filter is part of a 'Marineland Eclipse 3' hood, and
yesterday I added a Fluval 3+ filter to provide extra filtration. In both
filters, I have high filtration polyester 'pads' and there is a biowheel
running. There is also an airstone running.

The water has been hazy since December. I removed the gravel from the tank
in February - no improvements. I recently put the gravel back in the tank -
no change.

The haziness, is actually caused by very fine white particles. There are a
ton of them floating around. You can only see them from up close, but from
a distance you notice a slight haze in the tank (you can still see through
it). I am also running a tropical tank in the same room, and its water is
crystal clear... Both tanks are in a room without direct sunlight, but with
indirect sunlight (reflected) - there is never sun shining directly on the
tank.

I do 30% water changes once a week, the fish are all growing rapidly and are
very active. None of the fish are sick. I feed the fish ProGold goldfish
food (about 4-5 pellets per fish per day which they eat on the spot).

Here are the readings from the tank today:

PH = 7.6
Ammonia = 0
Nitrite = 0
KH Carbonate Hardness = 4 dKH or 71.6 ppm KH
GH General Hardness = 9 dKH or 161.1 ppm GH

I would like to know how to identify the cause of this problem? What could
be some reasons, and can anyone suggest what I can do to get the water back
to crystal clear?
