Oh its really complicated haha you add 1 to 2 teaspoons of kalk to per 1 gallon of RODI. You have to be careful though if you have periods of increased evaporation... I sort of adjust that accordingly. Helps to maintain cal and alk but not really raise it to a great extent.
It is messy and does cloud the tank for a bit so it has its disadvantages as well. I try to clean out the kalk sludge in the resevoire here and there as it tends to concentrate even if circulating with a powerhead.

I only recently started running chaeto but my research told me chaeto needs a dark period to respire in the light. Caulerpa is recommended 24/7 to prevent it from going "sexual".

"Interestingly, three marine microalgae, Skeletonema costatum, Phaeocystis globosa and Emiliania huxleyi,24 were studied for their rates of photosynthesis and carbon uptake mechanisms in continuous light vs. those same species in light/dark cycles (12 h on/12 h off and 16 h on/8 h off). The rates of photosynthesis were nearly twice as high with light/dark cycles as with continuous lighting. In two of the species (S. costatum and E. huxleyi), but not the third, the contribution of bicarbonate to the total carbon uptake increased dramatically in light/dark cycles compared to continuous light.
How this result might relate to growth and nutrient uptake in lit refugia where macroalgae are often grown to export nutrients is not known. However, it is a sign that perhaps continuous light is not optimal, in addition to being more expensive."

Don't worry about cleaning out the kalkwasser at the bottom. The ro/di will saturate itself with as much kalkwasser as it can and the rest will settle at the bottom. After I refill my resevior again i turn on the powerhead to mix it up and the rest which settled at the bottom is now saturated into the new refilled water. The "impurities" that settle at the bottom are nothing to worry about also, they'll settle again at the bottom after its been mixed up. I clean out my resevior once every 3 months.
Forgot to mention but don't continue to mix the kalkwasser in the ro/di. Mix it for 15 minutes after adding the powder to the ro/di then leave it alone. If you continue having it mixed you'll be adding an unabsorbed kalk slurry to the tank and then you'll get that white cloud in the tank. Ive experienced this the hard way lol.
Another negative of keeping it mixing or mixing it too long is that the kalkwasser water will actually lower its own pH. As it is exposed to air it will absorb co2 and lower its overal pH. I learned this from Randy H. Farley, I'm not trying to sound smart, just regurgitating information LOL
Sorry Dave for taking your thread off topic. :laugh:

Ok, here is my plan. I have a 40 gallon topoff reservior that I refill when needed with 5 gallon buckets. So if I mix the kalk in the 5 gallon buckets til dissolved, will I need to re mix at some point in the 40 gallon reservoir? If so how often?
And what are the benefits I should expect from this? Thanks Dave
And I am the king of OT, so derail all you like... HAHA
