we bought a house with a pool. first mistake. it's a 32000 L shape, salt water, vinyl liner, Hayward C900 filter thing, AquaRite salt water generator.
Pool man says don't put any products in the pool that contain metals, in other words buy from him at a 30% mark up. Pool was sparkling clear for a while, then turned nasty green and learned that d/h had gone to walmart for pool stuff and there were metals in it. Out of the entire summer, the pool has been clear maybe 3 weeks. The green was deemed to be caused by metals, so we put the recommended 'clean sweep' in and vacummed to waste, which lowered the level so we had to refill from the well pump, thus introducing more metals into the water...situation back to green. Shocked, did everything pool guy said but now when we vacuum, the stuff just shoots back out of the jets so we are attempting to move the green crud on the bottom into the deep end so that when we vacuum to waste, it will be faster and we will lose less water so we don't have to fill from the well again, thus creating this vicious cycle. (last time we had to fill, I bought 4 pre-filters for the hose, but that runs into big bucks too as one only lasts for about 1200 gal)
In the meanwhile someone said our filter, the Hayward 900 was insufficient for the 32000 gallon pool. What? So far this year we've thrown over a grand (so far) into this freaking pool, it really shouldn't be this hard. We make sure the salt is at the right level, check the ph and alkalinity but I'm starting to feel like I need a degree in chemisty to have a clear pool. We are considering selling the house just to get away from the swamp in the back yard.
I'm not really motivated to do this much work, as I rarely swim and had I know what a pain in the *** this was going to be, much less how expensive, I would have found a different house to buy. I suggested to d/h that we just vacuum the sucker to waste, and worry about filling it next spring. Cover it and forget it.
