Foamy bubbly top layer on L-Carnitine homebrew

[SulekJr]

Ran 600mg/mL L Carn at room temp thru .22 filters. One vial is perfect, and the other has a foam layer on top. Did I blow my filter? I used 10mL syringes with amazon filters

Mine gets foamy if I shake it. Then it goes away. Not sure if that’s your issue or not though.
If you’re thinking it’s a blown filter better to be safe than sorry.

Should just be air.. let it sit and check it in a bit. If it settles after a bit then your good.
