Kalkwasser anywhere in the equation Scott?
All the topoff water goes through a kalk reactor.
I'm amazed at how I am still constantly learning and refining/tweaking different aspects of the system. For example, the topoff water used to flow via gravity from the 55 gallon drum reservoir, through the kalk reactor and into the sump via a float valve. On more than one occassion, the valve would either clog, or get stuck in the closed position.
I finally realized that this arrangement was a disaster waiting to happen. I removed the float valve, and added an additional shutoff valve so that I could fine-tune the drip through the kalk reactor to match the rate of evaporation.
So far, so good. If the sump gets a little too full, I can just shut off the drip for a day or two.
Another plan I have is to elevate the skimmer above the sump in a rubbermaid tote. This will allow me to always keep the skimmer in the same depth of water (for consistency), and will also allow me to have it drain into the sink (instead of a salt bucket). With this arrangement, I'll be able to implement the "wet-skim" water change.
Gary- That regulator is oh-so-sweet. I've got that baby dialed in like a laser, especially since I'm using it in conjunction with the AC3. Too many times the old needle valve would get clogged, then suddenly burp way too much CO2 into the reactor. I dodged a bullet about a month ago over a weekend where I could tell from my internet connection on the AC3 that the needle valve was gummed up. (The effluent pH matched the display pH.) Then on Sunday, I could only helplessly watch (via the AC3 graphs) the display pH drop to 7.6 and the effluent pH hit 5.3. The solenoid on the regulator was stuck open! :fun5:
The building was locked, so I couldn't go in to stop it. I was constantly watching the webcam, waiting for the inevitable crash. I lucked out and things were fine by Monday morning, but I pooped a little in my pants.
Basically, any changes I make to the system will be to implement failsafes and/or improve the safety and reliability of the system components. The webcam and AC3 combo are really going to help with peace of mind this summer!
