This is the main problem for me here. Bought several brands, all of them smell really nasty. Washed and run water through for 30mins. Nothing change, It still smells nasty as before. Dish soap only masks the odor for few days.
There is no food grade vinyl tubing here where i live. Silicone tubing is too expensive for me. It costs 10-15x more than vinyl tubing. 30cents/meter for vinyl tubing and 4bucks/meter for silicone tubing (food grade).
I tried to give more distance for my Iridomyrmex anceps (long time ago). Plug the two meters tubing and left them for four hours (more or less) and when i came back, a lot of them were fainted. I used the same tubing brand before but it's only around 15cm and there was no problem.
Any tips or suggestions?
Thanks!
