@Polo I always remove the same amount of water not all and refill. Then smaller amounts between large water changes. 
@Snowboi Your right the tank is looking better today, think  it just needs some time to cycle through. I  dont use dechlorinator while change waters. When i orignally got the turtle I did some research and was told it was not needed.
Thank you both for your advice.  

Edit:Fliter crapped out on me this atfternoon, bought a new one.
