Hello Everyone

I'm planning to set up a small system in the Los Angeles area, and I have concerns about the high temperatures during the summer (winters are very mild so no worries). The area I have is full sun (south facing slope) and can get to 105+F regularly during the summer, and I'm concerned with hot water hurting plants and fish. To start I was planning a 50-80 gal tank, is this amount of water enough to deal with summer temps? Would a small shelter and or running fans over the fish tank cool the water (used this technique in my reef & fish tanks)? Do I even need to be concerned about these temps if I plan on raising tilapia?

I plan to start with:
3-6 strawberry towers
1 6'x2' grow bed
sump (like a salt water wet dry trickle system)
50-80 gal fish tank

Thanks!
