The ice ring is melting daily and there is no water in the bottom of pool, assuming leak but can't see one (yet). Do I bother with patching? or just buy a new liner, any recommendations for where/what type of liner to buy online for our above ground pool? I was told "20 gauge thickness" liner by installer. I know we could possibly get a prorated discount since our liner is only 6 years old but might end up getting better deal online versus the pool store where we purchased the pool.
