The WP 40 will help with flow, but might bother your LPS a bit, so you might need to get creative with placement.
You don't need a Ca reactor unless you need to supplement levels beyond what your water changes provide. You do regular good sized water changes, right??
If things aren't growing fast, Ca/alk won't deplete fast.
But you need to test regularly to determine consumption, then once it's significant, you can look at ways to replace. 2 part liquids, dosing or reactors are the most common methods.

I'm doing 20G water changes every 1-2 weeks. I keep my KH around 7 I think. How u suggest me to improve my parameters?
