I was in the process of precoating my filter with Diatomaceous Earth. However, I had left both return line valves to the pool open. One shunts water through the filter and the other directly to the pool. I should have had the return valve to the POOL off. Upon adding the six pounds of DE to the SKIMMER poolside I noticed the jets shooting out white DE. Some made it to the filter, but most made it directly back to the pool.
I am going to suck it up. It has been said that DE is potentially a Carcinogen. Does this create the need to empty the pool? Do I need to pre coat again? This was a stupid oversight, but Asi es la vida!
