Limiting factors that constrain gH carrying capacity ?

LowConductivity

Trying to harden up some water to grow out fry. It appears I'm able to add enough magnesium sulfate and calcium sulfate dihydrate to get the TDS up to 170ish...but I have undissolved leftovers on the bottom of my tub. The leftovers will dissolve on the next filling. What am I missing here? Do I need someone else in the mix to increase the amount my water can carry?

You can dissolve everything by using carbonated water from a sodastream if you have one or put an airstone in with the mix for 24hrs and see if that works
You could also try grinding the bits with a Mortice & petzel before adding to your mix
Sodastream is by far the best
