Yes, I use already peat for gardening in sock in harveyi tank but I think that it passed, I’ve 6,30 of pH…
My peat has pH 4. I’m looking for a gardening peat with lower pH that mine.
I’ll try to put peat socks in 30L barrel and I’ll see after a couples of days.
But the Kati Ani is the more simple way to have water with low pH…
