Liquid Soda Ash (BRS 2 part) precipitating even in small doses

[Adam_M]

Tank parameters

Temp: 78
Salinity: 1.025
dKH: 8.1
Ca: 460
Mg: 1450

Total water volume: 190g

I have been attempting to dose 20ml every day to maintain my alkalinity, but the soda ash is instantly precipitating into a solid upon hitting the water. I was not having this issue before when my Ca and Mg were a bit low (mg is actually a bit high now so I'm going to let it drop back down a bit), but now that I fixed those levels this has been my newest issue. I try to just drip in the soda ash slowly, but it seems to solidify no matter what.

Thoughts?

When I hand dose, I dilute it about 20 to 1 in RODI. It can form a white cloud but it dispels quickly and goes into solution.
