Quick update. Spent pretty much all day (outside of church) cleaning the garage and building my wife a shelf/stand thingy for her flower pots. Looks pretty good, considering how 'recycled' the wood was. I also rinsed the gravel as best I could before my back said 'no more'. Can't believe how much dust is in that stuff (Flourite Black gravel).
I will try and get out to pick up that plexiglas today...definitely going to have to reach into my welder savings now. Dag. Hm, maybe I'll take one more stab at an easy fix.
Here's a clearer view of the pump flow rate. It's also fun to watch the little waterfall.
