I work in a float center, and one of our pods has been unuseable for around a month. I do the general maintenence and cleaning, and this pod has given us trouble since day 1. It recently had the water chanced, but we must have done something wrong, as crystals formed EVERYWHERE almost immediately. The filter intake, the hair filter, the ozone, and the pool filter all grew crystals within a week. I was able to flush them out with some scrubbing and some very very hot water, but I fear the cryals have formed in the filtration pipes, as well. Is there any way to ensure the pipes are clear without calling a specialist? I am not a professional as far as maintenence goes, but I have been working with these pods for roughly two years and have picked up a few things along the way.
