We have a 75g planted tank with roughly 20 smaller fish. It's been running for 6-8 weeks, cycled, no problems etc.
The tank is pretty clear except when you're sitting next to it looking up towards the light. There appear to be tons of really small particles that are not being filtered out by a fluval 405 containing the prefilter, carbon, biomax and polishing pads.
What could be causing this cloudiness?
A view of a portion of the tank:
a poor attempt to capture these particles:
Thanks in advance for any ideas
