Dec, ten minutes on the phone should sort that out, but I saw several promising outlets, and I'm sure they could order if you don't find what you need. Or just use the links I provided...
I can make a good argument for NO foods at all, just rinsing the biology off off the compost. Now you can hold it longer (it's still dormant biology) and feed it up just before. Fish is an incredibly nutritive soil activator, and especially in warm weather it can over charge a tea in short order, especially an already low aeration tea, and some of the aquarium pump home units tend towards being underaerated.
I am just saying that this one addition is the one most responsible for tea overreacting and crashing. In summer we have little control on temp, and as noted, aeration can be spotty, so the other side of the "fire triangle" here that we can control is foods. Kelp is more a fungal food, so not so worried about that. Molasses is a quick sugar hit and great for early boost, but it doesn't have the staying power of the high nitrogen fish.
Hydrolysate is a more filtered product than emulsion (emulsion is just fish in a blender) which makes it more stable. I like Neptunes Harvest because of their cold processing and use of a variety of deep water fish species; many of the others are cooked monocultural products and while cheaper, are more volatile yet (break down easily and go bad).
