Overnight is fine. There is really only one reason for low ph and that is co2 wether its caused by a dirty tank or trapped co2 in the home. Either way it will only go so low and probably will never drop to a level of concern. It takes alot of co2 to get to that point. People worry about ph because they can. The ph meter is the worst thing for new reefer to own. The quickest safest fix for low ph is to take the battery out of your ph meter.

thanks for the correction and my question as well. If ph shouldn't be a concern, should it be alkalinity? If alk is good, then it is assumed that ph is good as well?
