  1. Default Is this a proper water change

    Everytime i do a water change, i do about 50% every other week, the water clouds up really bad a few hours later and remains cloudy for about 12 hours. I am growing out 4 peacock bass in my 120 gallon tank, then moving them to a 265 gallon tank in about 6 months it looks like. Anyway, here is what i do. I unplug everything, then syphon about 50 or 60 gallons out. Then i put stress coat dechlorinator in the water (enough to treat the whole 120 gallons). After that i attach the hose to the sink and start putting water back into the tank. When its all filled up, i plug everything back in and its done. ABout 2 hours later the tank gets all cloudy and the water smells horrible. I can't figure it out. Any advice would be helpful. By the way, i have had tropical fish in this tank for about a year and it was perfectly cycled. I had just community fish and i would say the tank was about half full of fish ( about 50 total fish, all small). About 3 weeks ago i took all the tropical fish out, and put 4 peacock bass in there ( all in the same day). So the tank should still well cycled, but i am detecting .25PPM ammonia most of the time, so i do small but more frequent water changes in between the big water changes. My little peacocks are eating very well and don't seem effected by all the commotion.

    If anyone could help out that would be appreciated.

    Try a different water conditioner like Seachem prime or Kordon amquel plus. The stress coat maybe reacting to something in your tap water, causing the cloudiness to appear.

    What are your current nitrate levels ? You can also gauge how effective your water changes are by the level of nitrates.
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    I once tried going the cheap route and bought some generic dechlorinator and it would make my water cloudy for a day. needless to say, I switched back to the good stuff immediately.
    Thar she blows!!!

    Nitrates are between 5 and 10.

    How are you refilling the tank? Does the hose swill the bottom or blow water into the tank too hard? In my experience, cloudiness is normally caused by sloppily pouring water back in and stirring everything up. Always refill the tank gently if possible. Hold a plate at the surface under the hose nozzle when refilling or try to slow the flow with your hand.

    In addition to filling the tank up slowly, how often are you vacuuming your substrate? Is it possible there's a ton of crud underneath that the new water is kicking up? When I do a water change and there's lot of stuff floating around, I figure I didn't get my siphon down deep enough in the gravel or get to enough areas. Just an idea.

    I fill it up very slowly. Usually takes about 15 minutes to siphon water out and about 25 to put it back in. Its a very bizarre thing going on. I have had tanks for 20 years and never had this happen. I think it may have something to do with removing the tropical fish and putting the bass in there, but i cant think of what exactly. Also, the ammonia has been hard to keep under control. Before i had the bass, the tank went about a year without an ammonia reading ( i check weekly at minimum.) Now, i am getting ammonia readings all the time. Very wierd. Bass are ok though, i change the water when its gets around .25

    5 to 10 ppm of nitrate is pretty good and sounds like you are chaning enough water.

    How do you test the ammonia ? What type of test kit are you using and have you had a LFS double check your results ?

    The reason why I ask is that sometimes, it can be hard to tell the difference between 0.25 and 0 ppm of ammonia on some test kits.
