I’ve had that happen before. The air draw was so strong it was just sucking the foam into the co2 scrubber and eventually filled it up and fluidized the entire canister. Ph shot up to 9.5. I did a 40% water change and put on fresh carbon and shut off the lights. Obviously took the scrubber offline as well. Water was white as a Gallon of skim milk. 12 hours later and the water was clear and parameters back to normal. No fish or acropora loss
