All clear. Great success.

Water change overflow fresh from the printer. So excited.
Can you explain more how this works?

Well done, really nice tank. Great to see the progression from bare bones through to this.

It’s a HOB overflow, but the inlet is 75mm below the tank rim. Internal baffle design allows a consistent siphon even if flow stops or water line is below the inlet. At 75mm, it’s a 25% water change, but if I were to add more water to the tank once it drains to the inlet height, the siphon will resume. It makes a 25% water change really easy, and if I decided to add more water it will drain without needing to pump anything additional. I’m testing it on the farm tank for now with a ball valve to stop the drain and allow me to fill completely.
I’d like to make another one with the inlet matching the water line so I can just leave it in perpetually.
Also, this is what TWO days of new growth looks like dosing Burr micros.

*So cool*. Have you performed a water change with it yet?
Could you post the link to the library where you discovered this? Any chance of uploading the adjusted model to Thingiverse?

I haven’t tried it on the display tank but worked flawlessly on the farm tank.
I actually found this on Thingiverse. I messaged the creator directly and they modified an STL for my specs. (8mm glass, inlet height, etc.). There’s a 150mm inlet height file uploaded as well that I have yet to print. I don’t have a printer myself, but fortunately the local library next to my office has a 3d printer that will print for filament cost.

Nice! I have a nephew in engineering school who is obsessed with his 3D printer, and would like nothing better than to print up one of these

I have a feeling it’ll be my next toy. My kids are 4 and 2.5 so by the time I figure it out it’ll make for some fun projects. I was once pretty proficient with Autocad and Solidworks but use ArcGIS Pro exclusively now for work. I’m hunting for the best open source modeling software to play around with because there’s like 18,305,792 things in my mind I’d like to create.Nice!

On today’s episode of “Stupid human tricks”…
James impulse buys an unnecessarily large return pump for almost no money.
I’ll either use it as planned for a closed-loop co2 reactor, or turbocharge my wife’s Hyundai.
How do you dial in your co2 in a farm tank with no livestock?
Turn the needle valve knob until you can’t distinguish individual bubbles because it’s just a steady stream of co2 and send it.
And the secret sauce:

Was finally able to sort out my canister filter setup. Was running two in-line through one set of Lily pipes; now separated so one for co2 driven by the external Jebao pump. The other is a dedicated bio filter. Hopefully encourages more frequent cleaning now that I can service one at a time.

Just left my dad’s house to borrow his truck and found a spare filter housing hanging around. Cerges reactor it is.
No hose clamps on your jebao pump? I’m not that kind of brave just yet. It has only been in the last year or so I’ve started trusting push to connect fittings for more than pneumatics.
Safety first. I used to strap my co2 and propane tanks in the car seats when my kids were small enough to need them.

So I’m using the smallest supplied 3/4” barbs with 3M silicone 12/16 hose stretched on them. Had to practically melt them in boiling water for them to fit. I don’t think I could get them loose/off if I tried.
I did the same and still put hose clamps on. I’m a bit nuts though. Probably a form of PTSD from when the turtle tank unloaded over night in our living room due to a filter connection.

Awe you’re using one of the little DCW pumps too. Cute little things that really pack a punch. Could not be more satisfied with this thing.
Yes, the thought of turtle water on anything makes me cringe. Totally get it.
