Having only one return in my IG pool and an AG pump to boot, I looked at this thing a few years back in hopes of boosting my circulation. I was getting some mustard algae in my deep end walls, was convinced it was poor circulation. The $99+ price tag scared me off. I've since found out my problems were pool store related, not circulation.

However, for $25 I could be interested. Especially if I can direct the flow upwards and vigorously aerate my pool to help with alk issues.
