Hi all. First time pool owner, have a few questions. First- I have a taylor k2005 test kit ordered which should be arriving today. So plan to post test results for advice. Second- I have what seems to be calcium deposit build up on spa water fall and ring around the pool. Can anyone give advice on easiest way to remove/clean? If I do a 5/1 acid wash, will gloves/mask suffice for PPE? Is it ok to let chemicals and residue fall in the pool then remove after the fact? Any pointers much appreciated.
