I am installing an aluminum above ground, 26' pool and I would like to reduce the chlorine used to clean the pool. I thought salt water would be a bad idea given the aluminum pool so I wanted to research a UV system instead. I would like any information on this

Is this a good system for this size pool? What manufacturer(s) should I be looking at? (I want to be sure that I can still buy parts in 5 years). Are the bulbs standardized or is a custom bulb that i must buy from the original UV light company? i am just learning so any information is appreciated. thanks
