Is this a joke?
I got a fluval c2 job filter but the water isn't any less cloudy. It's been 5 days with a carbon filter media. I am so frustrated. I have heard people saying that filter makes their tank crystal clear

Your water could be cloudy from a bacterial bloom, which will not be filtered out. Is the tank newly set up?

In any event, what is clouding the water is too small to be filtered out.

think you are going to have to give the bloom time to work out. 'new tank' is a good question.. is it?

I have an aquariapure filter. every time I feed this filter, I get a bloom. It disappears in a day.

if the tank is not new something is out of balance.

+2 - cloudy water is most often a bloom of zillions of heterotrophic (decomposition) bacteria typically the result of excess organic material in the water.
Often this cloudiness is caused by over feeding but sometimes just a water change triggers it (either organics in the supply water or simply stirring things up).
The other members are correct in that no filter can remove microscopic bacteria.

You might cut back on feeding. If you have gravel, you may need to do more aggressive gravel siphoning during the weekly water change to remove excess detritus from the gravel. Increasing the volume of the weekly water change can sometimes help.
Bacteria blooms usually only last a day or two, but may last longer.

i notice my water will always clod for a day or two after a w/c... im more then sure its due to not vaccuming mysubstrate.

It may also be your tap water, have you filled a glass of water lately? I've noticed that my tap water has been cloudy lately, (I believe someone on this forum said it's just oxygen bubbles, not sure though. I remember the cloudiness is harmless though :lol:) and when I do a water change it clouds the tank.

If not though, I agree with the others that it's a bacterial bloom. Although, what filter media is in the filter? You may want to look at adding a polishing pad (I use Sera Filter Wool, cut to fit) to help remove particulate matter.

hey, i'm the 0.02 round here..
if the tap water is cloudy, that is turbidity.
only problem with turbidity is that bacteria can 'hide' behind it.
and boiling does not make turbidity better, just worsens it (unless you are distilling the water).
trust me, I used to run a very small water treatment plant that serviced the small trailer court my ex and I owned and managed.
