Well....Mine almost do. I just don't want them to go any further. These are the first ones I have researched, so they might be overkill. But then again, they might just be the ticket. I don't know, so i thought i would ask the pros on here for comments about what I jave going on now.So far I have replaced the valves and pipes at the pump. Re-bed the sand filter, (it needed it). Fixed a leak at the skimmer, where it connects to the pool. Got the water balanced and clear. After that, i need advice and help.
