Would someone know why the ph values of water would change in 24 hours? My water is off a well. When I first started this hobby in Sept. of 98 the water tested 7.6 and very hard. Last night I tested the water and the ph was 6.5 and it tested very soft; same water source. I accidentally left the tube on the stand and this morning the water in the vail was extremely blue. Why would this happen? Could the drought affect the water parameters?
