If I want to dose approximately 2oz/day is there a pump / tank available to accomplish this? I am imagining a small tank with tubing to a pump. Then tubing into pvc. Might have to inject upstream of filter. With such a small amount I wouldn’t think this is an issue. The filter is full of water so it would dilute. Putting the pump on a simple timer is fine. Don’t need it tied into Pentair logic. Just have it come on during one the pool run
