Do I need a dosing reservoir?

[Sick_man]

So I bought a dosing reservoir but I think the part where the rigid tubbing connects onto the top is not air tight because I keep getting bubbles moving through, giving me inaccurate doses. Right now, I just put the tube straight into the container of All for Reef and my doses are spot on with no bubbles. However, I am concerned whether or not the All for Reef will evaporate causing much more potent doses since I can't close the top with the tube in there.

Is the all for reef container designed like the Red Sea containers which have a top made for connecting to the doser?

No, it is like the opening for a water bottle but kinda bigger

If it were me I'd find a way to seal it up and poke a pinhole in the top...if it's airtight it would create a vacuum. Or something like that.

I use these dosing containers. Fairly cheap and hold like 90 days worth of alk and cal
