Pool maintenance and long absence period

[joeed]

Hi everyone,

 

I will be absent for at least 3 months and I was wondering what I should do with the swimming pool.

 

Currently I have someone who is coming 3 times per week for the maintenance but I don't want to give him a set of keys during my absence.

He is usually cleaning around the pool and checking the water quality with a test kit, sometimes adding some chemicals directly in the water and I think that's it.

 

Can the pool be left unattended for 3 months or do I absolutely need some maintenance?

 

 

Any advice is welcome.

 

 

Thanks.
