Last night, I cleaned the cartridges in my filter. When I was reconnecting everything, I realized that there was an issue with the clamp ring knob assembly. I ordered a new part on Amazon which should be here tomorrow morning. I can't run the filter, so it will be off for the next 24 hours. The water chemistry is fine, but I was in the process of finishing a SLAM. How bad is this to have stagnant water there for an entire day?
