    Left TF-100 test kit in the sun

    Thank you. The kit is 3 months old. Looks like I will get a refill for the whole kit. Will I need to replace again next summer?

    Left TF-100 test kit in the sun

    I accidentally left my test kit in the back patio for a few days. The porch is covered but direct sun was on the kit for a few hours each day. Do I need to replace all of the chemicals? Thanks. This is my first year owning and maintaining a pool.
