That's actually really funny DB! (Not that you flooded your floor.) But I used those EXACT same words somewhere here in the RI forum. That my design worked perfect on paper, but obviously it wasn't perfect until I flooded my floor a few times.
If you have any pictures left over from those builds I'd love to see them and discuss them!
No doubt the CAP system is plug and play. But for the price I can't justify it for what it does and the components it contains. All of the basic elements are very simple, and it's a shame on me that I suck at general circuitry. For me, timers, pumps, check valves, etc are the easiest way to accomplish the system without getting down to the knitty gritty. I would also hard plumb everything to make sure tubes don't pop out of grommets under pressure.
In the past I built a 55g, bottom in-top out sand and gravel filter for my old man's koi pond. There is some decent plumbing work on that to make it work correct, 3 or 4 CV's, some ball valves and different line splits to skimmers, drains and other tanks. Anyways... I flooded the garage floor some many friggin times with that thing before it was done, and even a couple times after while I dialed it. But once it was right it was fine - and it works better than any commercial filter on the market. Partly because it's impossible to market something that you need to spend 20 hours hooking up yourself. There is 100's of these exact filters going around the country, all of our water looks like gin!!
Like I said, I'd love to chat with someone who's tried it before for cannabis.
