Hi everyone, pretty new to new custom water cooling parts bought indivudally.(Got a kit last time) I've recently completed a built - Late September. The Parts are below. EK Velocity CPU Waterblock AMD Nickel Plexi EK Quantum Kinetic TBE 300 D5 D-RGB Reservoir Pump Combo Acetal EK Quantum Torque 6-Pack STC 12/16 Black EK-AF Classic Angled 90 Black EK DuraClear 7/16ID 5/8OD Tubing 3m EKWB EK-CoolStream CE 280 Dual Radiator EKWB EK-CoolStream PE Classic 360mm Medium Copper Radiator EKWB EK-AF Angled 2×45° G1/4 Black Adapter Fitting EKWB EK-AF Ball Valve (10mm) G1/4 - Black Adapter Fitting EK Quantum Torque Plug Black EK Quantum Torque Micro Plug Black EK AF Extender 6mm M-M G1/4 Black EK Quantum Flow Indicator D-RGB Black Gigabyte Waterforce 3080 (Rev1.0) WB version (Confirmed it's nickel-plated copper) The coolant I'm using is the EKWB EK-CryoFuel Clear Premix 1000mL Coolant. I've flushed the loop twice with distilled water prior to filling it with the coolant. I've noticed that some of the tubes are going a bit green (See pics below) and there is a build-up of what I believe is corrosion on some of the blocks. I have a few questions that I'm not sure on; Can I confirm that I need to take everything apart and wash it clean? Ideally, I would prefer not to so I was thinking of flushing it with 5% vinegar and distilled water prior to replacing the coolant. Does this work as an alternative? For the prevention of future growth, is it worthwhile putting a strip of a Silver coil in the loop? The images below, That's corrosion right? I'm not sure what in the loop is causing it. Images here, let me know if you need any further images.
