i was wondering if anyone knew of an in-tank parameter meter kinda sorta like this one that i can use for my reef tank. where shops might carry something like this? any help is much appreciated.

Those are not very reliable and the drop testers are less expensive over the long run. Once you get your levels in check, just test once a month. That is unless you have a large enough demand for CA Alk and Mg.
