And after having two shoulder surgeries within six months of each other, even the simple act of cleaning the algae off the glass was nearly impossible. Necessities truly are the mother of inventions.

My AWC/Skimmer cup flusher. I drilled a hole on the top of my skimmer cup lid and inserted a standard 360° lawn sprinkler nozzle. A "shrub" adapter converts the threads to standard NPT, then a hose nipple. This connects to a PMUP in the last sump chamber that pumps/sprays water into my skimmer cup when activated. The water flushes the skimmer cup and overflows into the waste canister. The waste canister has optical sensors (high/low) and a PMUP to the house plumbing waste drain. The last sump chamber has an ATK unit plus a high and low optical sensor. I have a 20 gallon roto-molded tank mixed with new salt water. It has a PMUP into the sump and high/low sensors also. Basically what happens is between 9-11pm it waits for the ATO to run (so the level is proper). After that it pumps/sprays tank water into my skimmer cup and flushes it out. It does this until the lower sensor on the ATK opens (which works out to about a gallon based on my sump final chamber size). During the drain/flush the skimmer waste canister is pumping the old tank water+filth out to the city sewer. Then the fresh salt water is pumped in to replace what was drained. After about 20 days I get an alarm that my salt mix tank is empty. I flip a physical switch (breakout input) to turn the AWC off, push a button to trigger a fill solenoid from RODI. When it's close to full I add a specific amount of salt by weight and start a mix powerhead. After a day I turn the AWC switch back on, turn off the mix pump and I'm good for another 3 weeks. It took quite a bit of testing/tuning, and I simulated and programmed for any failure mode I could conceive. I love that I don't have to dump skimmate or smell it when it's getting full in the canister. Plus my skimmer stays pretty clean this way and I only clean it every 3 months or so.

Brilliant!
What's a PMUP?

My dosing tube holder made out of an old air bubbler manifold!

I feel as though I've done quite a bit of mods and custom one offs on my build. But nothing ANNOYED me more than testing cuvetts, syrngins, and all the other testing clutter. So I made my own drying rack to organize the chaos. Pretty happy with it ;D

That drying rack is outstanding!!!

I made a battery backup that is automatic and maintains itself.

runs for about 8 hours, enough to keep everything going in case of an emergency

Looks great! Do you have slots in it somewhere? Charging/discharging batteries generate Hydrogen, which is explosive at very low concentrations. Could be as easy as taking off a cover or two and routing some vent slots or drilling some holes to allow for dilution...

Theres vents in the back where they are hidden better. Also its a Sealed battery. Not saying it doesnt make hydrogen but its definentally not a car battery.

DIY close loop wave maker. Inlet on top, outlets on side. It's driven by a .5 RPM motor so the current changes from one side of the tank to the other in a 2 minute cycle. More of a surge maker than a wave maker.
