I really appreciate any help anyone can offer with our pool. It is a 30,000 gallon in-ground pool with a DE filter. We also have a small filter bowl for a ray-vac. Normally when you turn the pump on (it's a Challenger pump), it all kicks in and starts cycling the water within a minute or so...

Hi, Just opened our pool are are relatively new to this process. We had some stains last year, but more appeared over the winter. I dropped a few vit. c tabs on some of the stains and they came right out. The pool store tested our water and said I need to balance it before using ascorbic acid...

Just curious... if I need to increase my alkalinity with baking soda, how do I add the baking soda to the pool? Do I need to mix it with water? Do I just sprinkle it in the deep end? Thanks in advance for your help!

Okay, I feel very overwhelmed by our new pool and trying to figure it all out. (the pool came with the house, we did not put it in ourselves). This morning we backwashed the DE filter, however the valve to the rayvac was open when we added the DE ... does this mean all the DE was vacummed away...

While backwashing the filter we accidentally knocked the bucket of DE into the pool instead of the skimmer. There is now dust on the bottom of the pool - should I just keep brushing this into the drain? Will it ever go away and/or how long will it take? Is it safe to swim? Also wondering if I...
