It was a new heatercore but I didn't wash it out (I did rinse it, but that water was just filtered and sent back into the system sans Cascade). Could I get the black stuff off with ketchup? vinegar? New G5
.
I ordered a new inlet manifold from reefgeek.com as I can't find any pumps that perform as well at that price level (the Swiftech pumps are close but cost twice as much as a new pump and 15 times more than the new inlet). I have only become more unimpressed by all the work I put into this external box, and Now am pondering a new system with one of the Boniville 4x120mm fan heatercores and more efficient tubing layout hopefully in a lighter, more unified package.
*boo hoo*
