I've been using the Osmolator for the past 1.5 years with no problem. It never clogged or got covered in slime. You can locate the the 'eye' and 'fill line' seperatly from each other in the sump. Thats not a problem. You can even put the 'fill line' in a location where the drain is to mix the kalk/RO top off and dilute it better. I was just seeing if anyone connected theirs to a reactor before. Tunze sells a (simple) container to run inline, but I'd rather tinker and make my own reactor.
