re: Any of y'all have an intex type pool?

My wife bought an 18' round one on clearance about 2 years ago for $149. All I put in it is a bag of shock once a week during the summer and this thing. I run my pump over night and change the filter once or twice a week. It stays clear year round. Before I vacuum I make a whirlpool to get all the trash to the middle, makes it easier to vacuum.

ETA; forgot to mention, about every 3 week I take the copper rod out the ionizer and brush it with the wire brush, wear gloves when you do this.
