Mixing Feser One UV with Mayhams/EK pastel?

[Johny]

I'm pretty sure this is a bad idea, but just incase: is it okay to mix feser one uv coolantwith mayhams or ek's pastel additives?

Is there any other solution? I already have the feser one coolant in my loop, but it's not what I expected it to be under UV lights.

Thanks!
