Well @Sotex....... I do believe you just nominated yourself to oversee an AWESOME thread here. Well done.
As far as a whole forum goes, while I agree in both the need and coolness...... it’s hard enough to get active members here discussing all things in the pool universe, muchless a small specific offshoot of it.
But you’re off to a good start so let this be the new place for all things landscaping.
Good idea! We’ve been through a few different landscaping re-dos, so I suspect you’ll find interest in the topic. One thing I’ll add, which is a little off-topic but related, is the use of misters to cool down pool water. Lots of people try them and some have success. I was able to cool my water temp by 3-5 degrees, which was great, but the wind would blow the mist onto surrounding landscaping and it was killing my plants, thus the re-dos referenced above.
