Hello and thank you to all who created this site as I can see it will be greatly helpful as we learn this world. We're almost done with construction--coping and tile this week, deck and surface next week and then.....FILLING. Standard brick coping and tile work, 3 sheer descents, pebble finish and we're trying out the new-ish UV system. We were leaning toward salt but heard that the UV system kills all biologicals and is considered the new "green" way. We'll see. Very excited and hoping that Memorial Day weekend will be the "opener". Fitting as we're both retired military!!
