Well today was a "dumb" day.
For example, did you know that when you have one set of pumps pump one direction, and the other set of pumps pumping the opposite direction, that it doesn't seem to work very well?
Yes, I spent a good while fabricating/bending acrylic tubing to connect my MCP35x2 pumps only to discover I had it hooked up backwards when I did a leak test.
Pretty much went through a stick of E22 tubing.....well not ruined but not fitting anything at the moment.
Anyway I had to stop and ordered 2 Bitspower fittings I needed for hard tubing. "Bitspower G1/4" Silver Shining Enhance Multi-Link For Acrylic Tube OD 12MM " Thought I would try these, the rest of my hard tubing fittings for 12mm are the EK brand. Probably have them by the weekend since they are coming from PPCs on the other side of Florida.
