I'm not convinced that my plan will work at all. I find the information available online lacking and figure I'll try and fill in some of that gap. If it works, great! Maybe someone can use the info to use coral in their tank. If it doesn't work then the status quo is maintained and no harm done.

you could always do a few coats of a resin to the coral so it does not leach. i would think a marine grade clear resin would work. not sure how long it would take to cure though

Well, my experiment is over. I found that the coral was raising my GH level about 1-2 degrees a week which was resolved with a 30% water change. GH never got over 4 with regular water changes.

Based on my testing I'd say that dead coral is a viable decoration even for sensitive shrimp tanks as long as you are diligent about weekly water changes. If you were to wait a month or more then the GH may rise 4+ degrees and pose a risk for some of the more sensitive shrimp.

I decided to take mine out because I was tired of the look and decided to go a different direction. I will have to add a GH booster to my water to keep my GH above 0 for the shrimp now that the coral is gone.

Was your experiment done in just an empty tank?

Once you add livestock, almost anything organic in the tank will probably be acidic, which will react with the coral and raise your GH. I'd just recommend doing GH, KH, pH, and TDS tests for quite a while, to make sure that the pattern you've currently noticed doesn't change too much.

No, the test was done in a fully stocked fish/snail/shrimp tank. You can see the tank in my signature (12 Long). I tested for about a month with consistent results. I don't have a TDS meter so I couldn't test that.
