I re-read the article about adding DE to a sand filter.
I posted previously about a nasty algae problem, have been shocking like it is my job (funny, wife seems to think getting the pool straight should be my sole occupation ) and it is starting to make noticeable progress.
However, in terms of improving filtration I am considering adding DE to the filter.
Good idea or bad idea at this point? Clarity is better but still not where it needs to be.
Lastly, if you agree with this thought, where would you buy DE? I assume a pool store but are there better places to buy it as it looks like I will need a relatively small amount for the summer.
