Does anyone know of a reason why a phosphate reactor could not be used
completely submerged? I'm thinking of hooking one up directly to a powerhead and
dropping it in the trash can I use to mix up water for water changes. That way
the phosphates will never get into my tank in the first place.

I cannot think of a reason why not submerge it, but also,
I cannot think of a reason why phosphates would get into the clean water.
Especially if you are using RO/DI filters to prepare your salt mix.

Let's not get paranoic - you add more phosphates to your tank
with one feeding than you would with the filtered tap water...
