if you still need one message me. I'm 90% sure I have one in my pile of them.

Take a look or picture of the back of the controller or better the label of the power supply and it'll be easier to answer. It probably is 12V, and I personally have a bazillion of those in Redwood City.

For reservoirs, what I've done is buy the glass lids at Petco. They have a plastic section on them which is easy to drill for creating holes for tubing or float valves. Doesn't warp, but not as clean as what you did. Has other benefits though such as they have a hinge so you can open half...

I've actually designed a couple of those myself, friction fit without a screw. I had a similar style with a screw once, and it rusted. Nylon (or stainless) as that person mentions likely works well though. If interested I can track down the files.

I can't commit right now, but man these seem like crazy good prices ($60!!) for these pieces!

Some shots from today Things growing solidly. I've found another couple aiptasia, but this time I'm killing any I come across. I may need to get berghia again at some point, but I'll wait that out. I do need to clean the tank up, but haven't gotten around to it. Main issue has been I...

I can print one today if needed. Redwood City. Currently have something printing, but could be ready by afternoon. Text/messenger me (or dm if you can't find my number)

A couple interesting points ChatGPT in research mode found regarding the potential benefits of parallel: Here's the full result, but note that it seems to not be grok'ing the idea that in parallel the proposal was run the flow at half speed, so it's giving incorrect info about the dwell time...

Not to gotcha you, but if it's two pumps each putting out 300gph or a single 600gph pump going in parallel to two UVs, that's the same no? Both are just different mechanical configurations of the water routing. RE the sizing and what not, maybe I'm misinterpreting the original post, but I...

Sorry to belabor the point, and ignoring the extreme version I said and instead the one about the roads, if the consideration is maximizing time the stuff is exposed to UV light, the parallel and serial setup are the same then right? Assuming all other things the same, if the water is flowing...

If you pump water though two in series at 600gph, that's the same amount of dwell time as water going through two in parallel at 300gph. There's two roads that are 30 miles long running parallel to each other. The speed limit is 30mph. I send a car down each road. The cars will dwell on the...

I'm not completely sure that makes sense to me. There's likely some exposure curve to this, but if going slower doesn't matter that much, then generally there'd seem to be no reason to slow down flow either. Eg taken to the extreme, you might as well run full speed through the UV at max flow...

If you were running two, I would think in parallel is better. 600gph running through two in parallel is 300gph each. Less gph means longer dwell time. Longer dwell time means kill more stuff. If something gets through the first UV at 600gph why would it get killed by the second one?

I usually bring in a soft cooler. Will be a bummer if I start having to do the whole "leave it at the door" thing. That being said, this seems like a best case scenario for how this could've happened. Dude on 4k looking quality camera, obviously stealing. If anyone can get caught after a 1...

Zoas are pretty hardy. You can always do a high strength peroxide dip to clean em off. Either if you wanted to sell, or the next person who picks them up free, or getting em ready to try and sell to Neptune.

Future hack: if you have a gas stove or gas water heater you can float bags of hot water in the tank to try and boost the temp. Similar to floating bags/bottles of frozen water to cool it. A secondary electric source of course is an ideal, eg an ecoflow or a generator or just a neighbor you...

My experience is the inkbird probes. It starts as a little and then quickly tends to get out of control. One of mine I replaced the probe with another equivalent one bought from Amazon or AliExpress and it went back to normal. I am a big fan of frugality, but these inkbirds kill me. The Wi-Fi...

Can I get the chiller?

Do you own a multimeter? The most direct way to debug would be unplug both ends, connect the multimeter to both ends of the cable, and start wiggling things. When set to resistance mode, you should see it register 0 when the multimeter is connected to both ends. If the connection breaks, it'll...

Made some hexagon lights for my kids' desire to have a gamer room. Pretty stoked with how these turned out. 3d printed black outlines, white covers. Individually addressable LED light strips that I cut into 19 LED sections and soldered connectors to so it can be reshaped and pieces...
