Good morning,
Is it safe to leave my dosing setup like this? I'm dosing all for reef do I need like a connection bit for the cap? I'm having a bit of trouble with alk currently. I wonder if all for reef could be evaporating and throwing of my dosing but its more likely the reef flux I dosed a month ago.
