Hi, I have a build that is about 6 mos old in which...
the Singlularity D5 Protium Acrylic Top cracked and leaked into my D5 Next pump.
The RGB ring (accessory) which was plugged into the D5 Next shorted before I was able to shut things down,
but the D5 Next (and it's own RGB) was still functioning at the time I shut things down. (I'm hoping it's still ok)

After buying a new EK Kinetic TBE combo/Top/Reservoir and tearing things apart in order to rebuild, I've noticed a film inside my tubing
and in the old reservoir which led to some further googling on the subject.

I chose DP Ultra based on recommendations and the fact that the D5 Next's flow meter is calibrated for it.
However, I now see the Ethylene Glycol base along with my uninformed decision to use PETG hard tubing was a bad idea.

I have a decision to make now and was hoping someone could provide some advice.
Either I switch to a non-Ethylene Glycol based coolant or switch to acrylic tubing (or chromed copper/brass).

If I switch to a different coolant, how will this affect the D5 Next flow meter? Will it still be useful if perhaps offset by a certain amount?

If I re-tube with acrylic, can I be certain I won't have this film on the inside of the tubes/reservoir?
I'm slightly concerned because the Protium Top/Reservoir was supposedly "acrylic" - however the inside of that reservoir looked terrible..
with a 'film' of sorts and in addition, with the top cracking as it did (multiple fractures throughout), I'm feeling a bit wary of
an ethylene glycol based coolant at this point.

Would appreciate any experienced advice..

Thanks much.

Thanks.. so I've decided to re-tool with acrylic..
and after looking at the reservoir of my Protium I'm going to move to a non-ethylene glycol based coolant to boot.

Basically, I want my tubing and coolant to appear crystal clear and I think a simple type formula is more appealing.

So now, I'm just wondering about the D5 Next flow meter.

If I'm using say.... Mayhems X1 (?) How 'off' will the D5Next Flow meter be?

*note - I'll buy the 'High Flow Next' if it EVER appears for sale in the US near retail prices.

But.. until then, if anyone has offsets or correlated info on the D5Next flow meter with alternate coolants,
I'd be interested in an attempt to make that function useful in the interim.

thx again
