Yeah I think that's the one where rhizome recommended I use GH's SubCulture. I thought it was extremely expensive. ($65 for 6 little packs.) But then I figured out it's 1/10 tsp. per gal. so it's not bad at all. It comes in a water soluble pack ready to throw in your 50 gal reservoir.

Ha, I'm such a dork. I'm supposed to add 3/10 tsp. to my set up and last time I added 3 tsp. I wonder what 10 times too much will do?
