I looked in my sump today and theres like foam or i dont know how else to explain it in there... i checked my water parameters and ammonia, nitrite, nitrate are all 0. Last addition to the sump/tank was just adding some chaeto to the sump that i got on ebay. Anyone know what this is or why this is going on?? Theres a pic below.
