Has there been a correlation yet with elevated levels of Calcium and faster growth rates? I usually just keep it between 400-450. As for the Phosphorus, is that a direct 1-1 conversion to P03/Po4? Or do you have to multiply it by a factor similar to the Hannah checkers?

BRS did an anecdotal study showing that elevated Major elements yield faster growth rates. As far as the phosphorus conversion...I'm not sure if you're not talking about converting from PPB to PPM.

Ah cool with the BRS study. I'm curious if you get a direction correlation between phosphate to phosphorus levels? Or is there a conversion factor.

The short answer is no, however I would personally trust the tests as a ballpark number. Phosphorous can exist in many organic and inorganic ways. We have all kind of figured out the limits of what we should ball park and know which relative level works.

Having said that, I would highly recommend everyone understanding the difference between organic (compounds bound in organic matter) and inorganic (reduced to the compound and floating in the water column). The difference is significant because corals are able to get to organically bound nutrients in a way that algae is not. This has made me a firm believer in high import, high export. Put more food in your tank and pull it put before the organic stuff breaks down to the compound level and your algae has a shot at it.

I am using AWC to try and keep them stable.
Which salt? Regardless of salt, your parameters will be stable with a daily water change. Just curious which salt is producing those results for you.

How many gallons a day? Hopefully not manually [emoji4]
For daily water changes, you want to stick to the 1-3% range.
