I have a 24` by 52" above ground pool.
with an aquaflow 1HP pump
currently I have a small sand filter wich I got from craigslist a few years ago for $50 but the 4 way valve is starting to leak and it does not seem to filter good enough. I have high Iron in my water. I am debating getting a DE filter will that be beneficial for high Iron? or would a cartidge be better? I do not have alot of money and will be saving over the winter months. so it will be for next year.
