Algae stuck in corners

[kp1783]

Hey all.... need some help..

I've vacumed and brushed and cannot remove algae stuck in the corners for a above ground pool. I've even gone as far as using the broom from the garage and it still doesn't budge... Any other ideas ??

thanks

Are you sure it's algae? Try rubbing it wil a chlorine puck - if it comes off it is organic, if it doesn't try rubbing some crushed vitamin C tablest in a sock on it, if it lifts or gets lighter it is a mineral (metals) stain.
