Hello. So after a long battle with contractor, I am finally getting my pool replastered. Currently it is SGM River Rok Lucayan Blue, well it was supposed to be as it never looked like Lucayan Blue. Long story short, I am now working directly with the pool plastering company, and the guy, an ex SGM employee, told me the only way to have Lucayan blue correctly is to be a slave to the pool by checking water levels every several days, brushing, etc. He recommended for me to go with Diamond Brite, cool blue, and add additional stone chips to give it a deeper blue. I on the other hand, since I paid extra for River Rok, I prefer to stay with such brand. He told me if that was the case to then go with River Rok Imperial white. My fear is that it will be too white. Any thoughts or recommendations? Thanks
