I'm amazed no one has asked this.....especially since we have the developer right here ^^^^
Instead everyone is distracted by the simple things like "no way it works" or "it costs how much??!?" Maybe it's just the engineer in me.... This concept is certainly feasible and by no means fantasy with enough money for mega-fancy sensors and pumps. The hard part is finding "good enough" pumps and sensors that are reliable enough for the job, at cheap enough prices for the masses.
Okay now that we have the skepticism out of the way....
I haven't heard a single thing about how this will integrate with other people's systems. For example,
Say someone has an ATO on their sump. They just drop a grand on this spiffy little tool. How many mL does this thing suck per test? Say it's like many of the standard test kits out there, 5mL per test. Say it's testing only dKH, pH, NH3/4, NO3, PO4, Mg, Sr, I, Ca. The big ones. At 5mL a piece that's 45mL a test-set. Say you have this thing going once a day, your ATO is now backfilling exported saltwater with freshwater thinking its evap.... In about 12 weeks we've already exported a gallon in tests....and back filled with fresh.... Now if you have a BIG system.... This may not be an issue.....
Point is, and I preach this at work probably 5 times a day, automation is good, but over-automation is real. Even with this system you likely will be looking at a different-new kind of maintainance routine. Yeah, might not be testing parameters, but it'll be something else!
Also, the idea of this machine pumping the unused portion of the water it draws in, back into my tank.....if any of you have ever worked in a ChemLab.....or a restaurant filling ketchup bottles, you must know that you never ever pour what's been poured back into the source.....ever! Being that many of these testing Chems are extremely deadly to aquatic life (look on the box or instruction book of your test kits now...) I don't want any reverse flow into my tank. I want a completely separate, sealed location for chems and for the test-product-waste. Far far far from my tank.
