Been thinking about running kalk in addition to my calcium reactor.

What do you guys think? I've seen lots of successful tanks run kalk in conjunction with a reactor and have seen some impressive results. I've always either ran kalk or a reactor, but never at the same time. Kalk has lots of benefits such as increasing ph, precipitating phosphates and maintaining alk and calcium. Here is my question. Instead of using a kalkreactor, I plan on simply dumping in some kalk into my 30g topoff reservoir. The reservoir feeds into my sump via a Kent float valve. I would also hook up a small mj pump to keep it stirred 3-4x/day via my AC3. I know that I have a risk of the kalk plugging up my float valve, but it is an acceptable one. Does anyone see any flaws in this setup?
