The gunk is definitely from the Mayhem, since I see it forming in the foam if the water is run fast through the loop (even on day 1!). The precipitate in the image formed over about 2 years time.
There are plenty of additives that won't gunk up your loop....it's the plasticizer that is gunking up your loop in this case.
Can you find me anywhere, just one single place that Primochill (and not a random poster in a forum) claims that Advanced LRT is plasticizer free? It's not. Never has been. And you are probably the fifth person I have seen post that it is in the last week (and, of course, showing a clear plasticizer issue and saying that it must be something else.....). What is up with that?
This is straight from Primochill, not a single mention of it being plasticizer free:
PRIMOFLEX™ ADVANCED LRT™
PrimoFlex™ Advanced LRT™ Tubing has been designed, formulated, and manufactured for today’s evolving standards in the PC water cooling industry. Advanced LRT™ has been carefully formulated to perform in a wide range of closed loop cooling systems, creating the most compatible water cooling tubing ever created.
LOW RADIUS TECHNOLOGY
PrimoChill’s proprietary blend of notably low durometer PVC and more rigid polymer resin provides PrimoFlex™ Advanced LRT™ with an unbeatable bend ratio and durability. PrimoFlex™ has been tested in exacting laboratory set-ups. This included tests with abrupt small radius bends and multiple directional changes. Advanced LRT™ tubing resisted both twisting and collapse in test results. This allows for tighter bends eliminating kinking that can cause cooling failures and reduction in system performance.
CLARITY IN SIGHT AND MIND
Smooth inner walls improve closed loop sanitation. Advanced LRT™ smooth surface inhibits particulate gathering or entrapment onto the tubing wall. This reduces the potential of bacterial growth and contamination. With this technology, Advanced LRT™ will keep your system looking and feeling as clean as the day it was installed..
SysPrep & Liquid Utopia™ INCLUDED
COMPLETE RETAIL BUNDLE
Included in the package at no additional cost is a 15mL bottle of SysPrep – Cooling Loop Pre-Treatment as well as a 15mL bottle of Liquid Utopia. Any successful venture into water-cooling starts with a true cooling loop preparation which can only be achieved by using Sys Prep™. It will “flush” your loop and its components of any debris left by the manufacturing processes of your reservoir, block, pump, or radiator, leaving your water cooling loop clean, clear, pristine and ready for any type of coolant. Once your LRT tubing is crystal clear the Liquid Utopia offers a full line of protection against algae and corrosion.
START TO FINISH
PrimoChill has you covered from the beginning of your build to the end. For the first time a bundle is available that harmoniously matches a perfect tubing solution with a cleaning solution as well as a distilled water additive that ensures a clear, clean, and protected cooling loop!

This tubing is designed to work with 1/2in. x 3/4in. compression fittings or 1/2in. Barb w/ 3/4in. Clamp.
Note: Due to a lack of tolerances in fitting design, we have seen some minor issues when using LRT tubing along with strict size brands such as Bitspower.

SYSPREP™ – 15ml (Cooling Loop Pre-Treatment)
UTOPIA™ – 15ml (Algae/Corrosion Protectant)
With the use of different components, materials, fluids, and flow rates, results may vary with the appearance of your tubing. Although Advanced LRT is designed to work with a large variety of cooling components the use of alcohols, Ethylene Glycol and as well as any other harmful chemicals is strictly prohibited and will void your warranty. Tubing will stain if dyed coolants are used. PrimoChill is not responsible for any damage caused by or when using this product.
If your fittings seem extremely tight when using our tubing there are some methods to navigate around this issue. One method is to dip the end of our tubing into very hot (not quite boiling) water prior to installation. This will make the tubing more pliable allowing tight compression rings to be mounted easier. Using this method will also create a seal between the tubing and fitting once the tube cools creating an added layer of security.
PrimoChill is not responsible for any hardware damage. Use at your own risk.
If you don't want plasticizer issues, get yourself some Tygon A-60-G or Tygon 2375, both of which are actually plasticizer free.
