Preventing Seiryu leach

Hello friends! I've attached a shot of some of my beloved Seiryu stone. I purchased the stone being aware of the issues associated with it leaching, and so I also purchased some UNS aquasoil to remedy the carbonate leach. Unfortunately, the aquasoil was either very overstated in its ability to prevent parameter changes and adsorb carbonates from the water column, or the amount of Seiryu was just too much for it to handle. Either way, the soil did very little and I'm dealing with the dKH climbing to 10+ between weekly water changes. I'm typically doing 70%+ water changes with 1 dKH remineralized RODI water, so there's a significant amount of leach occurring. This means that I either must remedy this leach, or say goodbye to my Seiryu stone.

Here's my possible remedy - dipping the stones in a clear concrete epoxy, like what I've seen people coat concrete tanks with. The stones would be dipped or painted with the epoxy and allowed ample time to cure, then they could be reintroduced to the aquarium.

Can anyone think of a reason this may not be a good idea? I don't know long term outcomes on epoxy sealed concrete tanks. I don't know how/if the fact that this is a high-tech tank running abundant amounts of CO2 would cause problems for longevity. I don't know if my pleco will cause damage to the epoxy and potentially ingest bits while trying to eat algae off of it.

Any insight on this would be appreciated. I'd love to keep my stone, but I can't have parameter swings like this.
