Can you test your tap water ph and your tank water for comparison. Post the results of each.
Where the fish acting fine, before the water change?

The fish where great before thwe water change. Tap water PH is 7, Tank PH was 7.5 before the water and is 7.5 now. I also lost 4 more fish last night, and the tank is so cloudy now i cant see the fish in the back. ( im hoping more are not dead back there.) Could the problem be that i put 2 new plants and 3 new zebra danios in??

Did you dechlorinate the water used?
What's your Ammonia, Nitrite & Nitrate in this tank?

I highly doubt its the plants causing this issue and if the Danio's brought in a sickness it would more likly be something like ick, not cloudy water,

The tank did not appear cloudy till after the water change? Did the water from tap appear clear? Did you preform a gravel cleaning during the water change?
As Angel already asked, did you dechlorinate the new water?
What test kit are you using and how does the tank test for ammonia, nitrite, and nitrate? How does the tap water test for ammonia and nitrite? Also, can you post a picture of the tank?
I know, lots of questions, but hoping the answers will lead to a fix.

Ok here we go lol, yes the water appeared cloudy after i did the water change, the tap water was clear, I DID DO A GRAVEL CLEAN AND MOVED THE DECORS DURING IT, yes i dechlorinated the water, im using an API 5 in one test strip which test GH, KH, PH, NO2 and NO3. GH=120, KH =180, PH 7.5, NO2= 1, and NO3 40ppm, thats way to high isint it??? I dont know what the ammonia is, im going to have to go to petco and have them test it to make sure, untill then ill just use a dose of amquel plus to remove it. But yea from the pic you can see my model pleco, and that its rediculously cloudy.

Ok, two more questions.
How long has this tank been setup? Did you wash the gravel before using it?

Please post the results for ammonia, when you have it. IMO, your no2 "nitrite", is too high. I would do another water change of 50% to lower the nitrites.
When cycling a new tank, I try to keep both ammonia and nitrites under .25 ppm.

I lied, another question. What filter are you running?

What kind of fish died?

Perhaps you have disturbed the tank too much?

I dont know how long this was set up for but if it was running and well established, sometimes by disturbing deep substrate may have release toxic gas where such fast death may occur. i am not saying this is what happened but possibility.
Denitrification process involves dead area (under the ormanents/rocks over period of time) and nitrate reduced back to NO2 and then to N2O then N2 which is simple nitrogen gas escaping to air. Perhaps nitrite reading from such process if no ammonia is present?

If tank is new, less than a month or 2, tank may not have completely cycled yet.

It is hard to speculate exactly what happened but finding out the rest of testing should shed some light as to what happened.

Hope tank settles w/o further loss or complications..

Keep in mind that "Cloudy tank does not necessarily means water is bad nor crystal clear water is good water".
Thus dont judge the water quality by its clarity.

And obtain better test kit than strips when possible.

Well I did also do a filter change and used one of those carbon filters. Perhaps I dint rinse it enough before using it? The tank has been up for about 2 months to. I also lost bala sharks , black Molly, glo fish, but not all the Molly and glo died.
