Hi, I think I am interested in getting a pool cover. I live in Texas, so freezing really isnt an issue. Previously I have just left the pool uncovered, but I have a lot of trees nearby. Every winter the algae ends up taking over cause of all the leaves, and I don't have time to keep it clean. Any recommendations on a mesh cover vs a leaf net? Also, my pool is L-shaped. Is it okay to just get a larger rectangle cover? It would be cheaper than getting a custom made cover.
