  1. IIRC, the Aquabus 12v power has very low amperage and is only capable of carrying a signal; not powering a device. Neptune goes to great lengths warning people not to plug their USB devices into the Aquabus port.
  2. I would research their natural depth and environment to help narrow your search,
  3. Remove the sediment filter and carbon block from inside their housings and re-run your checks. If TDS is still higher, then it's an instrumentation error. If TDS #2 drops so that it's the same at both locations, then the filter or carbon block is releasing tiny amounts of dust. You can run additional checks with different combinations to figure out which is causing the increase. Either way, I wouldn't worry about a slight rise in measured TDS _before_ the RO membrane. The sediment filter and carbon block aren't intended to reduce TDS anyway. The RO membrane will take care of nearly all the TDS, and the DI will remove whatever gets by the RO.
  4. I crosschecked it with calibration fluid, but I may mix up some of the RHF just for fun. Good idea about mixing the salt mix. My first batch of water was 50 gallons. I thoroughly shook up the bucket of remaining salt, and my next 50 gallon batch was just as bad.
  5. 35ppt salinity, and 640 Mg. Tested with refractometer and Salifert test kits.
  6. I don't normally test my new saltwater for water changes, but I recently mixed up a large batch of water using IO salt and just happened to test. Alk was only 4.5dKh, and Ca was 250. I point that out because variability in water change water can also mess with your alk trend.
  7. You need to replace the fitting. The fitting will be under pressure with any kind of an auto shutoff valve. Grip the broken part with pliers and unscrew the fitting. Or use a slotted screwdriver to unscrew the fitting. If that doesn't work, buy an inexpensive bolt extractor.
  8. I had to tighten mine a couple times at first to get it to stop dripping, but it's held fine for the past 5 years.
  9. That's a great idea. Make a 5 gal bucket worth of saltwater and 5 gal for the Brute trash can. Put them next to one another in the same room, and compare ammonia between the two. If ammonia rises in the Brute and not the bucket, then the problem is with the Brute.
  10. If you had a wide diameter pipe and a mostly-closed valve like in Alan's sketch above. And the end of your drain pipe is not submerged in the sump. Then water would fill the upper portion of the drain pipe, but only a small stream would squirt past the valve into the bottom pipe. The water would "fall" through the bottom pipe into the sump due to gravity, instead of flowing through the pipe. You'd never get a siphon below the valve. Of course, that's a poor way to design your overflow.
  11. Is it possible we're using the term "full siphon" differently? When I say "full siphon", I mean all water and no air, regardless of the flow rate. It appears to me that you mean "a full-rate siphon, unrestricted by a valve". Because, if the tank-to-sump plumbing is filled with water, it's a siphon. In which case, we're all in violent agreement that a pipe full of flowing water is silent.
  12. I expect the sand-bed-sump arrangement works best when the sump is elevated enough to put plumbing and a pump under it. That's a more difficult arrangement for most people than a simple sump-on-the-floor setup. Also, you probably need to change out the sand or vacuum it periodically because all the detritus will settle there. Like what most of us see in the bottom of our sumps, but more because there's no skimming or other mechanical filtration. Not bad, just different. Finally, skimmers provide a lot of oxygenation to the water. You have to be willing to give up the extra buffer that provides when something else causes a reduction in oxygen I suffocated some fish once when I turned off my skimmer and a noisy MP10 in my Red Sea Max. The return pump was still running, but it wasn't enough on it's own to keep the tank oxygenated.
  13. You might add a few pipe hangers to prevent the torque Zygote2k warned about. They're a couple dollars each.
  14. I put a tee just underwater on the discharge end of my full siphon drain. I found it greatly reduced turbulence, noise, and salt creep.
  15. Looks like ich. The white dots are sores where the parasite burrows in, not the parasite itself, so you can't scrape them off. Concentrate on feeding the fish healthy food and provide good water quality. Your other fish have definitely been exposed, and may have low level infections.
