Good Day:
I recently swapped out my live sand with 20 lbs of Caribsea Arag-Alive Fiji Pink sand from my 28 gallon JBJ tank yesterday and did a full set of water test today (10AM lights off).  I use Reefer's Best salt and do not dose anything.  I typically do a 4 gallon wc every two weeks or less.  I have always had a problem of low pH and Hardness/alkalinty.  It seems low but stable and was wondering if there is anything you would recommend.  The only livestock that I have difficulty keeping is snails for some reason.  I am not sure if this is related to ph/hardness.
Thanks,
Michael
