Toxic Salt Buildup?

I'm starting to show toxic buildup on my hydrotons and pots. I know flushing them will get rid of it, but it takes a little while to completely take care of the problem. So are there any additives I can add to my water to disolve the salt faster?

I use Clearex from Botanicare every two weeks.

Right on, thanks alot.

clearex or flora kleen, i recomend you do a flush using one of these products atleast once a month, salts build up fast and can throw your grow outa whack
