i just set up my vivarium, and after putting water in, i noticed that it's murky and some substrate has made it's way into the water feature. i created a barrier with some rocks, and used some aquarium gravel to fill in the gaps. now my mini repti-fogger isn't working right, and the water is a clear red. i've emptied it and refilled it, and it looks cleaner than it did. any suggestions on what i could do?
