I recently bought a house and it has a pool. My pool knowledge is pretty much at zero. Up until recently we had a pool guy come and look after its needs but he will no longer be helping us out. The pool equipment that came with the house was quite outdated, a single speed pump and a Zodiac vacuum. So, I went the pool store and after talking to the sales person bought a Hayward VS pump and a Pentair Rebel vacuum. I have read a bit on the forum already, specifically about CYA levels, and this looks like a place where I can learn quite a bit.
