Well it's obviously an air issue.. I think a bottom diffuser system would be alot better than your fountains and sump pumps, fountains in my opinion are nothing better than cosmetic just my opinion.. Nows definately not te time to add cutrine plus it'll just kill more vegetation in turn sucking more air and adding nutrients to your pond.. There's not alot you can do right now I'm surprised you haven't got more response but the forums usually pretty slow on Sundays..

I believe in catch and release. I catch then release to the grease..
