What kind of diffuser are you using? Have you tried to squeeze the yeast/sugar bottle and see if any bubbles are coming out? Did you "cure" the silicon as directed?
None right now. Its not in the tank, I have it going from the yeast mixture to another bottle to act as a bubble counter and there's nothing even coming out there. Reading the silicon it says cures in 5 minutes fully bonds in 24 hours, I let it sit for 3-4 hours. Would I need to wait the full 24 before it makes an air tight seal?
