If you can't find the extract that seachem offers locally in Denmark and ordering it is too long, then maybe you should go and check out a health store or pharmacy? Garlic extract is readily available
I put some small pieces of shrimp in a Little cup, then i chopped some garlic over it, Then i put it in the cooler, and left it there for and hour with garlic all over it. Then i took a piece out and attempted to feed my front.. No succes, but i just did a massive Water change, like 3 hours ago, so not reading to much into it. Ill let the other pieces lay in garlic the night over, and attempt tomorrow afternoon Again with it. Will that be to much garlic in the food? In denmark we normally use Garlic pills instead of Garlic Extract, but ill take a look in the pharmacy tomorrow.. To be honest im starting to suspect other illness, or internal parasites. Any signs i should look for? Maybe i've slagged a Little on the Water changes, i just dont think so. But Again, i havent tryed other food than frozen shrimp and earthworms.
