KH doser blockage

[bkelly]

Hi Mindy, right now im using Elis soda ash. i read maybe the tubing can cause problems with restrictions (something about the silicone line and less friction?), do you use air line tubing im using the white RO tubing but do have it feeding into the sump water. Although the doser on my nano is dripping above the tank and gets build up. so perhaps the chems? both can crud up in a week .
