I accidentally put about a 1Qt of vegetable oil into our 30K gallon gunite pool. Worse than that, thinking the filter would take care of it, we left it. Now our pool is GREEN. I've done a little research and read that I should treat it with 6X the normal dose of enzymes. Is this a good plan? Should I treat with an algeside first? What is the best product for enzyme treatment? It gets worse with each passing day. Any advise you can offer will be helpful.
