PrimoChill ZenCoils Tube Reservoir Calming Coil - UV Brite Green

primo chill zen coils this is a pack of one zinfoil this would be the black one and this would be the red of course i got red and black for the frank build but they do make them in multiple other colors and the purpose of these are calming coils they are to calm the water going into your reservoir as that water starts pumping in through the top it creates all kinds of turbulence through your reservoirs and what these coils are designed to do is to be able to give a surface along the edge to break all that turbulence up and keep that water from just being so active within your reservoir and it truly calms that water down that's why they're called zen coils is to break up a lot of the air bubbles and that kind of thing so whenever it comes out of the bottom if you're routing your stuff out the bottom everything is going to be calm and it's going to have a reduced amount of air within that
