Hi everybody i'm Don and new to the forum.
This weekend my wife put bug repellent and sun block spray on my kids. my son who loves turtles decided to play in the turtle tank up to his elbows every day since Saturday while i'm at work. I noticed a funny smell coming from the tank and when i started inspecting it it smelled like a swamp and chemicals. the water was a cloudy murky yellow and my step niece's res(2 inches) that im baby sitting hasn't eaten since saturday and stays tucked in its shell. my 4 and 5 inch res are the complete opposite they're swimming around eating like pigs and full of life. idk if the filter crashed i've done one 100% water change and 2 50% water since saturday and put the baby in its own tank and still nothing
idk what to do any ideas?
