Water turned brown please help!
Last evening I did the standard check for PH and PPM; everything was in a good range. My PPM was around 600 and the PH was about 6.3. I woke up this morning to really muddy looking and bad smelling water. What could have caused this in less then 24 hours? I should mention that I am new at this and I transplanted from dirt two days ago so it is possible that pathogens got introduced but it seems unbelievable to me that crystal clear water could get so "infected" in a such a short time.
