I'm going on a 7 day cruise in September and will be gone a total of 9 days. I'm leaving my in laws who are 73 years old in charge of my pool during that time and I guarantee you they wouldn't understand the whole testing of the pool. Is there a timer that I could put on my pump to run automatically? It's 1.5 hp so I'm not sure if there's one that would pull it or not. Also I was thinking I will watch my pool log for a pattern of how much bleach it's taking and bump it up a bit per day and measure it into gallon jugs and tell them to dump one jug per day in and dump the skimmer basket. I normally brush and vacuum 3-4 times a week on alternating days but I know that neither will happen while I am gone because they are also watching my dogs. I know I sound paranoid, but I just brought this pool pool to sparkling clear from a green swamp and don't want to go through that again. Thoughts? Do you think this will work?
