I have crushed coral in my tank now and was wondering if i could remove some of it and replace it with live sand so i would have sand on one side and rock on the other. does anyone have a mixed bed like this and is there a drawback?

Its fine to swap out the crushed coral for sand but I would not use "live sand" I would just purchase dry sand (carib sea seaflor special grade reef sand is highly liked around here).. Rinse it first too very well with regular tap water to get all the fines/out

Live sand has a lot of "dead" in it despite the name and will just cause more problems than its worth on an existing system.
