Hi I have axies in outdoor pond, a month ago it rained really heavy and mud came to the pond (the water became,obviously, dirty, but all the particles sedimented and only get dirty not muddy), but with lot of effort (changing water a little per day) the water became again clean. a week ago my dog threw a pot filled with earth, and the pond became dirty again, i was trying to clean it, but it does not get better (not worse, but not better). may I be worried about axies´ health? do mud (it does not have too much, a little in the bottom but I say it again, the water is brown) affect axolotls?
