"Cloud Wars" an ongoing battle to the depths of he

So before my tank was cloudy and white particles were sticking to my glass. I would wipe down the glass and it would stick right back on.

So I then proceeded to vacuum the gravel, wipe down the sides, and then add Accu-Clear which got rid of the white stuff that kept sticking to the sides.

The next day the tank is still cloudy so as the directions said I repeated the Accu-Clear treatment.

The tank is still cloudy!

So any information on how to get rid of this would be great.

Also if anyone mentions to do a water change, I have this one question for you.

How many water changes can you do in a certain amount of time were it is safe for the fish so I don't lose my cycle in the tank?

I have a 20 gallon tank with Guppies, swordtails, platys, a snail, Otos, Corys, and an Birchir.

first thing I should ask is what are the ammonia, nitrite and nitrate readings in your tank?

Water changes can sometimes cause cloudiness in the water. It can also be caused by excess feedings and recent gravel vacs. What happens is that whenever there is a sudden increase of nutrients in the water, you get a bloom of heterotrophic free-swimming bacteria. These are not the same as the beneficial bacteria that grow in the filter and on other surfaces. The cloudiness is not harmful except for the fact that the waste product of the bacteria is ammonia so sometimes you see a sudden increase in ammonia, so its good to test the water. To answer your other question, water changes will not really affect your cycle because the beneficial bacteria is not free-swimming and so you arent really getting rid of the good stuff when you do water changes. You can shock the fish if you change too much at once and changing too much at once also puts a lot of saturated gas into the tank which can cause respiratory and osmoregulatory problems.

Personally what I would do is let the tank be. Usually the best way to solve cloudiness is to let the heterotrophic bacteria do their thing and fade out on their own. Cut down on feedings as much as possible and if you have to do a water change, try using distilled water since is contains little if any nutrients. Remember if it is a green cloudiness then you are dealing with algea and that can often be solved by keeping the lights off more.
