Hello, I'm redoing my tank and had to order some csm+b and the ei package was only 2 bucks more so I went that route which is good for you! I have an extra .5-1lb bag of k2so4, kh2po4, and kno3 that I want to ship (US only, no Hawaii or Alaska) to someone who is possibly just starting out and is looking for some dry ferts. I got these about a year ago from GLA. I really want to keep this RAOK to people who actually need it. Shipping is on me too. Start a numbered list and I will pick a random winner tomorrow Sunday by 5pm eastern time, shipping Monday or Tuesday. Thanks!
