Alk at 20kh and CA at 200ppm

these numbers come straight from my ro unit!! it is a cheap 3 stage unit that came with the house when I bought it. The filters were just replaced last week. The source water is coming from a well. Will adding a DI stage fix this and make it 0?

API ALK and CA test kit used

Something is bad wrong. If the tap water is really that hard then you shouldn't be able to take a shower without clogging up the shower head. I'd be checking that out with another test kit.

That's what I thought. I tested the ALK in my tank multiple times and it come in at 10dkh every time. That's higher than I want so I started trouble shooting and checked my RO unit. I guess I'll try with a different test kit and possibly by a new RO/DI

I would get a better kit, API isn't the greatest. FWIW I live in limestone country, growing up we had a well, it did clog shower heads every 6-8 months. The main line from the well pump had a gate valve on it with a bad stem packing, if you turned the valve off and back on, it would leak from around the stem but would seal itself back up in a couple days, just from the buildup. It is possible that your alk is that high but your ro/di should be removing that so I would also double check to make sure the membrane is seated properly.
