Hello. I have a fairly new tank; 10 gallon; 1 inhabitant (a blue lobster or crayfish or whatever you want to call it). It's been clear for 2 weeks, but over the last few days it has gotten very very cloudy. The TDS was 150 ppm this weekend; today it is 490! All other parameters are low (Ammonia, nitrite, nitrate) all below 5ppm. What is the cloudiness? Is it a bacteria bloom? Should I let it be or change the water? Thank you.
