It took about six teaspoons in maybe 350 ml. of cooked food to get the consistency I liked. It gels real fast. I tried with less and the food broke up in the water a bit so I reheated it and added more agar. Ten minutes later it was set and worked great. I though it seemed better than gelatin but who knows? I'd like to try gelatin at least.
I'm not sure, lol. I bought it from chad320, he said a lot of the serious crypt growers use it to grow crypts and since this is almost a crypt only tank I figured that it would probably do me and my crypts some good.
