Chlorinating liquid and bleach (and also Lithium Hypochlorite powder) will add salt to the pool about twice as fast as Trichlor or Dichlor. But that doesn't matter very much unless the salt levels get very high. You shouldn't worry about it. Saltwater chlorine generator (SWG) pools have a salt level of around 3000 ppm, for example.
If you use powder for shocking, which is probably Dichor, then that increases the Cyanuric Acid (CYA) level and makes chlorine less effective. For every 10 ppm FC added by Dichlor, it also increases CYA by 9 ppm. You either need to maintain a higher Free Chlorine (FC) level to compensate, or use a supplemental algaecide (at extra cost), or not use products that increase the CYA level, or dilute your water through drain/refill or more frequent backwashing (if applicable) to keep the CYA lower.
You should invest in your own good test kit -- either the Taylor K-2006 or the TF100 at tftestkits.com.
