When I had a solid PVC cover on my pool of similar size as yours, it cost 16k , 3 years ago. The cover is great , but not suitable for large pools as ours with funny shapes. Was an absolute torture to remove. And the length made the poles sink into the pool.
Last year I finally had enough and called some other companies to find out about other nets. The guy that saw my pool immediately told me that DPS plastics had done my cover. When I said how he knew, he said they were the only company that would install a solid PVC cover over such a large wierd shaped pool and they are not suitable for them.
Anyway, finally dumped the thing and installed a leaf net cover in the last month, which is so much better and now that wild oak tree finally lost the battle. I can now manage the cover by myself , whereas with the solid PVC cover, we needed three people minimum
