Johannes,
Greetings. Sorry for the delay in getting back to you. We do not have T. Iso paste but do grow cultures that are very dense, un processed, no preservatives. The density is usually 12-30 million cells/mL and can be used to start your own cultures or fed directly to a tank. The T. Iso is a good microalgae, it is rich in essential fatty acids, has been used successfully to raise clams(food), copepods, mussels, etc.
I have not shipped to Germany or Australia yet but we can work something out I am sure. We have other products you might be interested in as well. You can contact me directly at
eriks@algagen.com and we can go from there.
I appreciate the inquiry
all the best
Erik
