algea in pool

[tara15]

I have a sand filter. The only problem is that the pressure guage is broken. My mother in law didnt bring in the filter last year and it cracked and broke in the ny winter. Is DE earth? should i try to add some anyway? Its been so cold and rainy here on long island that i might just close up the pool anyway. If i do, should i try to change the sand next year and if so, do you reccommend any type of sand? I heard of this stuff called "zeobrite". Have you heard anything about this type of media? sorry for so many questions.

Tara,

Before you invest in zeobrite (or anything else), replace your pressure guage. It is a valuable tool in pool management and will cost you less than Ten bucks.
