Cant get KH and Ca powders fully dissolved

[See Gee Sea]

Hello all - I'm using Seachem's Reef Builder for alkalinity and Reef Advantage for calcium but whenever I mix either - no matter how long or how aggressive, I always get undissolved power at the bottom of my ATO. I'm mixing them individually and in a separate container before adding them to the ATO. Even 72 hours later I can still see aggregate swirling in the tank too. Any suggestions?

Those two chemicals may need to be kept separate at all times.

Their most likely binding together and precipitating.

Have you contacted SeaChem?

I haven’t yet. Thanks for the suggestion!

The better method would to be to dose kalk with an Auto Top Off system.

Pharma Kalkwasser (Calcium Hydroxide)

Ultra-pure Kalkwasser for Reef Tanks! BRS Pharma Kalkwasser is not your typical calcium hydroxide. It is made from an ultra-pure source that contains extremely low amounts of aluminum and compared to traditional kalkwasser you can actually see the difference. If you are adding Kalk to your ATO...

for each solution, try to heat it up in microwave then stir till powder completely dissolves.
I do this with 2 part and always get clear alk and cal solution.

If your pouring them into the same ATO container then they’re precipitating. They need to be dosed separate

Update: THANK YOU for all the suggestions! I dumped the RO tank and mixed each separately and problem solved. My brother the PhD polymar chemist didn't mention to me to mix them separately (I can blame him ) No cloudy water, no precipitation! Now of course I need get that participate off of the rocks it settled on. I was ecstatic to see coralilne algae growth on the marco - funny how little things make us excited.

I wouldn't be so kind to him. I'm a polymer chemist too. lol
