How often do you run the Polaris? No trees in the backyard, other than palm trees, so no leaves to worry about...but MANY critters...frogs, lizards, and bugs in Florida...
We leave Sherman in the pool all the time, just pull him over to the side when swimming laps.
M cleans out the skimmer and there's almost always a frog in it. In the beginning of the season, it's not unusual to find a small snake....which is another reason I don't even take the lid off!!!
It doesn't have to be emptied out every day, nor does Sherman's "bag"....just when needed.
The chlorine tablets go in the skimmer....they are about 3" long and 1.5" in diameter.
We've had a real problem with "yellow mustard" in ours....I think it's some kind of fungus or something like that. Since we took over doing it, instead of the pool company....we haven't had it back at all. (knock on wood) We were told it has something to do with all the trees we have....lots of maple and oak....and the frogs.
We empty it every fall(put an electric pump in the deep end), put the cover on it(we have one of those green ones that supposedly an elephant can stand on). Then first part of April, if the weather is nice enough....we take the cover off, pump out all the water...usually it's at least half full again of really nasty water!! Pressure wash the whole thing, pump out that water, then wet vac the rest out. Then refill it. It's been working really well...this was the 4th winter we've done it this way.
When the pool company did it, they'd pull of about a foot or so of water, throw some chemicals in, and cover it. In the spring, they'd tell us to flip a corner up, and fill it up to the tiles, throw a bunch of chemicals in and tell us it was fine. Ha!! The last time we had them, the yellow mustard got so bad, we had to empy in mid season, they came and acid washed it, we refilled it, and we still had problems....
$300-350 a trip.
