Many of the customers that we open and close their pool, we also maintain the pool on a weekly basis. On a regular schedule we will arrive and conduct such services as: vacuum the pool, maintain the pump & filter, recharge the auto chlorine feeder, test the water,make chemical adjustments when necessary, shock the pool occationally, and empty the skimmer baskets. Weekly service is growing for Holland Pools and we want to do what we can to make it grow. Finally, Holland Pools has invested in the very best water testing device available, a spectrophoto meter.
