DIY aquaponics help

Hey yall take it easy on me if I sound stupid here.
I have a duck pool that I'm transferring into a a.p. System i understand that duck poo creates a high ph. Do yall know of another critter, possibly fish, crawfish or something along those lines that will still help with nutrients but cut my ph. Also it is my first time growing and I'm open to any and all cost effective solutions...
