What's with my water clarity?

[BigDaddy]

Should I stop vacumming my gravel for a while?
I have been adding a couple fish at a time since may.

In between what time spans?  When you add fish, it is usually a good idea to let about a month pass before you add more fish.  This allows the biological filter to grow to handle the increased load from your fish.

white will eventually turn green if you leave your lights on(ime)

not agree
when the water satr by beeing brownish , yes you can say that, but white i dont think so.

well here what i do :

in a 90g gallon tank well planted , i start getting the water trouble (like someone add some milk , not a lot in the water).
i decid to try GreenX but i think of it (dont like adding stuff).

so i buy some polyester foam , as fine as i can (wall mart or any othe shop have that) and and put a very nice shunk on a aquaclear 200.
add on more tube to the entry of my AC200 to be able to reach the bottom of the tank

and i put the filter on the tank.

2 days after i notive the water getting more clear

few advantages :
- mecanical filtration
- and moving more the water
- you can check the color of the foam (originally white)
- add a bit of biological filtration

of course if you have CO2 , stop it , it will be waste of CO2

ok why i take a AC200 and not a AC300
because i want move the water but not my tank becomming a torrent, i already have 2 filter (ehiem) and 1 power head.
and second , i dont want when i remove the AC i remove a nice peace of filtration.

try it , no matter what he can hurt
ok take time because the 200 is small but ....never know
