we have to skimmers, two jets, and two floor drains. There is also a cleaner line on the wall near the deep end. We don't have a robot yet, but we have the hook up...hopefully get one before the end of winter (Maybe a little cheaper!)
We have a salt system and the nature 2. The salt system was nice on the skin, but i do not think we will use it again this year. The salt has already ruined our brush that we used to brush the plaster. I can't imagine what it is doing to the inside of our system. My wife is actually pretty good with testing the water and she just tells me what to add.
With the Nature 2, we really like it. It is so easy to use and requires no maintenance, just checking the water like you would normally do. The salt was so much to get it right and actually working, we are not even going to bother with it this season and my just have it removed. We got it for free as an incentive (The controll panel was not hooked up yet at the time of the photo i posted). After researching everything on line about both types, there were postive and negative about both. After just one season, we like the Nature 2 better.
Along with the system, they hooked up a few things with our lines that make it easy to use. Not sure if every system is like this or not, but we have a solar re-currculation set up that pulls the water from the surface and pumps it out through the floor drains to warm the pool faster. It also has a brush mode so that when you brush the plaster it sucks it down through the floor drains, robot mode and regular vaccum mode. It was very confusing at first, but they gave us a guide so we can reference it to ensure that the valves are set up the proper way. Again, it could be something that every one has, i just thought it was pretty nice to have all of the options available with just the turn of a few valves.
We are still learning and will probably think differently by the end of next summer, but for right now we are very happy with everything and can not wait till the spring.
