If i did this right the pic should be one corner of a temple after being drained, I all ready have sand walls from the ocean floor to the top of the water. I set the partitions 3 blocks apart instead of 5 because I'm working with only 24 sponges and I'm lazy and i don't wanna dig any more sand than i have to, so i figure if I'm gonna have to dig, empty a section and move a wall. yes it's gonna take a while but i think it will be well worth it in the end. I also invested in 2 beacons, thanks to Buda on smp7 for having acouple in stock, makes the guardian annoyance less annoying. Half slab walk ways and capping the sand walls keeps mobs from spawning (make sure they're upside down.) creepers kinda put a damper on the build.Draining the inside was done by Gawadrolt. thankswill try to keep this updated if anyone is interested in following. mind you this is a learning experience for me and I am all ways open to suggestions and ideas.
