(Actually now that I think about it, Magnesium is even better than zinc, its lower on the table)

That works until the beneficial magnesium gets to the RO membrane, whose job it is to remove any solids, including the beneficial ones... My source/tap water has fairly good calcium and not bad magnesium levels. I worked with it for quite a while, but am glad I went to RO/DI recently for my system, I can see the improvement after three water changes. Too bad there isn't a way to extract all the good stuff before the RO takes most of it out, well, there probably is, but I reckon you'd need quite a chem lab to make it happen.

Thanks for all your help. But I hope you can help me now, I found a small stumbling block...
Most of units I am looking at are 15-18" tall and I only have 11"-12" max height to work in under my sink.
Does anyone know of any units that are about 10-11" tall and can put out 25-55gpd?

I bought the aquaticlife power unit works great...what I like about it everything is enclosed and you change the filters from the top. But it’s around 15” tall however it stands on its own base so you don’t have to mount it.
