Our flow light on the intellichlor is red. It did this before, and I asked my pool builder about it, he said I needed my pump running at a higher speed, it has ran since September (when pool was installed) at this same speed and has been fine until now, so I turned it up to a higher speed, the flow light turned green again, but the pressure on the filter showed that it was time to clean the filter. So I took it apart and sprayed out the cartridges, this was about a month ago. The flow light is now red again on the intellichlor, is it normal for the cartridges to need to be cleaned again this quick? Or is it possible I need to clean the intellichlor? He told me I should not need to clean the intellichlor yet.
