So for my first WC build I used 2 MCP655 pumps in a single loop. Temp wise, these have absolutely done the job. Where they've let me down is with the aesthetics of the plexi case that I threw together. They are advertised as pumping 300 Gph but the reality is nowhere near that. I was expecting enough pressure to push water clear down the top of the case before the waterfall that I built in but it's nowhere close. The water is just tracking the bottom of the run and condensation is hiding the view. I'll try attach a picture here to illustrate it. I'm thinking about replacing one of the 655s with either an ehiem 1262 or an mcp35x. Does anybody have a suggestion for which one to pick?
Here's what it currently looks like:

Here's where I'd like to have the water pushed out to:
