Are any of your fish at the top of the water gasping for air? How is your Air Pump? Plenty of bubbles? How long does it take for the bubbles to burst once they reach the surface? Do they sort of look soapy? Do they accumulate, get big and take a few moments to burst? This is a sign of Phosphate, a deadly killer.
