No, though I did get the pellet making kit, I haven't gotten around to making any yet. Everything is doing so good with increased traces via Plantex CSM (thanks, Rex) that I've gone on to other projects for now. I dose the traces and KNO3 separately. I'm experimenting with both the K2SO4 and NaPO4. One tank is doing nicely, the other is suffering a bit, perhaps lighting is the true culprit there however.
