Salt & Chlorine feeder inline

Hi. I’ve recently converted my pool to salt. In doing so I removed an inline chlorine feeder which I would use stabiliser tables in. – like this one: http://spartanpools.com/images/Rainb...r_InLine_1.jpg

I find the chlorine levels in the pool are fine but the stabiliser levels are now low.

My question is, is there any harm in having both the salt cell and the chlorine feeder inline?

Thanks
