Vivi nova and other cleros turning my juice dark

[Turbo311]

I have been vaping Highbrow's RY4 as my all day vape, It is a darker juice. The problem I'm having is after I refill my Vivi mini up 2-3 times the juice at the bottom of the tank is really dark and the taste gets off.

I know to just clean the tank at that point but I'm wondering why is it getting so dark? And is there anything I can do to slow it down?

Thanks

Top coils seem to wick the thinner parts of the juice faster leaving the heavier particulates for the end.
All top coils do this to some degree and for me, Vision clearos seem to be the worst.
I would test a top coil by pouring the remaining juice left over from 3 fill-ups into a dripping atty.
The results are always the same, unvapeable.
The wife would just pour out the juice; fill and vape on, of course this can waste a lot of juice over a period of time.

Another reason to clean and flush after each tank. Plus dark juices tend to foul the coils much faster, so frequent dry burns are essential.

I normally get about three tankfulls before the remaining 20% is too dark and thick, which is when I dump it out and clean it. I find that refilling tanks when they are about 1/3 or more full keeps remixing so that it's still fairly thin and light. I'm probably tossing out 5 to 10 percent of the juice overall, but tell myself it's the stuff I probably don't want to vape anyway.

I also think that this is the same material that's in the bottom of a used filler-based carto, but since it's visible it gets our attention.

I just figure it is the way it is, and dump the thick dark goo if it changes the taste. I just factor that into my daily total, and then dumping it doesn't bother me.

Cut back on the voltage a tad. Use the volt/ohm/watt chart to make sure you're not cooking the juice. Cleaning is important as well.

I figured this was the problem on my previous Clearomizer just received my Stardust V2 with long wicks and haven't noticed the darkening of the juice yet but at 2.8ohm and 4.4v this thing eats through my 70%pg 30%vg juice. Is this more of a Nova/Stardust issue or would turning the voltage down a tad save some juice.
