Re: [APD] Micron filtration and nutrients

I have a HOT Magnum that I like to put on the tank once a week to polish
Which elements, if any, will be stripped from the water column from a
filter. I believe Marineland says the filter is good for particles down
Would any of the macro nutrients be removed? What about traces?
Just curious... Otherwise I'd run the micron all the time as a secondary
some additional movement in my 75 gallon.
Atoms are way, way, way, way smaller than 4 microns. If your filter could
get anything like the size of elements, it would be filtering out the
water molecules as well... i.e. it wouldn't let the water through (this
technique is regularly exploited in many household objects, such as
kettles, saucepans and cups!)
Most of the macro nutrient, such as NO3, PO4, CO2 etc are simple, small
molecules, and are (at a very rough guess) at least 10,000 times smaller
than 4 microns?
It's not going to remove anything that is dissolved.
