I have successfully completed my Baqucil conversion. I am here to tell you I have not seen my pool look so good since we first put it in. Anyhow, it is time to change the sand. I priced all around, but hardware stores, for the filter sand. Can anyone tell me if they have had experience with the expensive Zeobrite ( may be spelling wrong?) about $45-$50 for 50 lbs, but equals 100 lb.? Also has anyone just gotten silica 20 sand at a hardware store? What are you pros recommending? Zeobrite is suppose to do a wonderful job, but that was salesperson online???? LOL OR should I just stick to going to the Pool Store, and pay $10-11 a bag? They may be going under beings we have not been in much at all this year!! LOL
