Snap......i have cloudy tank syndrome as well, dont know if there is a lot you can do its probably some type of bacteria in the water, i have read that this can happen if you have a new filter running (as in my case) but i dont know how true or accurate this is.
Mine is a type of milkyness in the water, its cleared a little bit but not much, ive been running the tank for about 2-3 weeks but only added plants in the last week or so but the cloudyness hasnt changed one way or the other with the addition of the plants.
I have kept the carbon filter running for the moment, i know this isnt ideal for plants but i want to try and eliminate the cloudyness of the water, but by the end of the week im going to remove the carbon filter and leave it out as i dont think its doing that much to help the problem anyway and by that stage the carbon will have been running for 3 weeks.
Im sure it will go eventually and in the meantime ill continue to do water changes etc just like normal.
Is your tank running long or have you made any changes lately, filters etc or did the cloudyness just appear quite suddenly?
EDIT: my plants seem to be fine with it, they are pearling etc im sure if the water was clearer it would help the plants lower down the tank but the cloudyness isnt that bad that i would worry about it .
Its more annoying to look at than anything else.
