Hi, I had twelve Norman’s Lampeye killifish and after subsequent dosing with Colombo Floragrow. I dosed when doing a 10% water change with RO and a day after, one or two fish are hyperventilating and hanging at the waterline. They don‘t survive quarantine. Is this sensitivity to fertiliser in general or could it be specific to this brand? Has anybody else had this experience? All water parameters are normal and stable.
