If the pond does not have bottom aeration, then all regular specialized pond bacteria will not work very well because most of the best, fasting working decomposing bacteria thrive in well oxygenated warm environments. Ponds without bottom aeration develop during the warm season cool anoxic (no oxygen) sediments that kill all the good aerobic bacteria leaving behind anaerobic bacteria that work very very slowly - 20-30 times slower. Mixing the sediments in all areas of the pond bottom when aerobic bacteria are added will result in the fastest decomp of the leaves and organic sediments.

A clear water swimming pond goal that receives lots annual tree leaf input is a problematic mess. Even swimming pools under trees receive lots of leaves that causes lots of extra work and extra filtration effort Both IMO, are bad situations.
