I would be extremely interested in how it works, do you think the size of the bubbles would effect anything? Like using the small tip as opposed to using a bigger opening tip? Nice, my alk is at 170 and I need to lower it but my mom and wife are dealing with most of the chemical stuff while I recover from my eye injury. I had gotten it down from around 260+ to the point it is at now though using the aerating method. I was just pointing the nozzle towards the surface though, it was working but slowly.
