We have a Triton II sand filter with a G3 Barracuda. Our pool is in serious need for replastering. About 2 years ago, we had a new motor installed as well as replacing all of the sand. It was determined by the professionals that the sand particles had become too rounded and were not effectively filtering anymore. Subsequent to replacing the sand, there was a sparkling clarity for about a week, then a return to a cloudy and eventual greenish color despite adherence to standard chemical maintenance efforts. (Cl between 2.2 - 3.4; pH between 7.4 - 7.6;). I've had numerous and various pool experts analyze water samples and they have all offered their strategies for this problem. None have worked. In my reading of the Triton product, it may be likely that one or more of the laterals got damaged, either by the new sand installed, or just wear and tear. In any event, after I backwash, a huge plume of material blasts from the returns when the pump is returned to it's normal filter position. I've resorted to sweeping the pool while back washing to completely remove the sediment/algae/detritus, but this is time-consuming and wasteful. It seems then that I must remove all of the sand from the filter to see if my assumptions are correct. How long will it take to do this; can I save most of the sand for reuse; can the filter be emptied without disconnecting all of the leads? Thanks for any suggestions~

This may be true for Florida, where the water table is higher than say, Arizona, but surely, *never* would then rule out ever replacing the water when it cannot absorb any more chemicals. I suspect that the sun would do more damage to the plaster and possibly the gunite as well in the southwest, more so than any hydrostatic pressure.

Any swimming pool contractor (especially in Florida) will tell you never-ever, ever drain any swimming pool regardless as to what the pool is made out of. Hydrostatic pressure under a swimming pool can have a very devestating effect if a pool is emptied. A very good example of what I am talking about can be represented with a empty glass in a sink. Take the glass, flip it upside down and hold it there while filling the sink with water-the upward pressure on your hand is similar to that of the water table affecting a pool. Hydrostatic pressure can break pipes, break the pool itself, make the pool rise out of the ground, break surrounding decks, to name a few. Homeowners insurance usually will not cover such an incident if it is caused by owner error. I dont know if you had the pool installed your self or it was in the house when you bought it; regardless, the point I am making is the same-good money was spent on its installation. Pools are getting more and more expensive every day, protect your investment.
