I have 3 cubic feet of OMRI listed 100% Canadian Sphagnum peat moss that I use to brew tannins for my 55 gal. It’s much more “cost effective” to me. Are IAL tannins required for conditioning and spawning? I was thinking of using those tannins and floating java fern for the bubble nest. I’m sure I can find styrofoam somewhere in my house too. Good plan?
