Cement washed off into new fibreglass pool

[VanD]

Hi
The surrounds of our pool was concreted and I was worried that excess concrete was scraped into our newly constructed fibreglass pool by the pool builders. They also washed off excess cement into the pool. Should I be concerned? Will this be a health hazard and how will we remove the cement and stones?

Thanks in anticipation

Tell the total idiot builders to vacuum it out as they put it in there and don't pay their bill until they do!
No long term worries, just vacuum it to waste and not through the filter
