Is this powder diatomaceaus earth? this is used as an insect killer and its "chemical composition of diatomaceous earth is 86% silicon, 5% sodium, 3% magnesium and 2% iron" (some random internet minerals source).
Seems like an unecessary risk to put a substance, although seemingly inert, into your tank that is primarily silicon. We all know silica/silicon causes diatom growth so why add nutrients specific to grow the organism you are trying to get rid of...?
If you have a diatom problem there are many other solutions (ie: cleaner organisms to stir sand, silica removing resins, various mechanical filters that dont use silica, UV)
If your issue is water clarity try to improve the efficiency of your filtration system by cleaning it, adding a micron mesh bag to the sump return, and regularly cleaning sponge filters.
