I never had this issue in my previous tanks, but this issue seems to be buggin me, perhaps others who share the same concern as well. I have a 90G tank with a pair of 350 penguin HOB filters for mechanical filtration and a 30G sump for biological filtration. As for stock, I have 9 JDs(1" in size) and a 7" pleco. I found out the issue and it's coming from my HOB filters. If i unplug them, the mist of tiny bubbles don't appear anymore. I figured my HOB filters aren't doing a good job at mechanical filtration, so I inserted some floss infront of the filter cartidges. It made no difference. Anyone else having this issue with these HOB filters? I thoroughly cleaned out the filters too. I hate looking at this tank with mist floating in the water that eventually rise to the top.

Anyone else know what I'm talking about?

Cheap sugesstions to keeping water crystal clear?

thanks in advance!
 
filter socks ?
might want to try something around 180-200 micron, they are pretty cheap too. under 10 bucks
 
I like filter socks also how much of a waterfall is coming from the HOBs? I am assuming there is no air running at or near their intakes?
 
There is no air between the intakes and the filter itself. The filter sits nearly a quarter inch in the water. Before, the water level was much lower than the filter, but after raising the water level, the microbubbles have decreased. Still, it's noticable and i WANT CRYSTAL CLEAR!!!

How effective are the filter socks?

It sounds more like the intake is getting air or something.... Like not from the water column but somewhere in the intake process.
 
i have no idea.. the only tank i do any water polishing on is my planted tank... and for some unknown reason thats the only tank that ever has "stuff" floating around in the water....
 
looks like you air is getting into your filter or somethin... how long has the tank been running
