Dissolving powder additives?

[njparton]

I use Seachem's Equilibrium powder to add mineral content to RO water prior to adding it to my tank.

I replace water in batches of about 35L but I have problems getting even 1/4 to 1/3 of a teaspoon of powder to completely dissolve in the RO water. This of course has a knock on effect for the GH readings I take. No problems with the 1/2 teaspoon of baking soda I add though.

Does any one have any simple solutions for making sure 100% of the powder dissolves?

I've tried adding small amounts to mixing jugs and stirring etc, but no real joy...

I would heat the water up a little first, just like making a cup of tea the sugar dissolves better in hot water than cold.

I would do like Scales

Get some of your water hot (i'd boil it) and mix your powder in there then mix it in with the rest of your RO water

OK - good idea - I'll give it a whirl
