My possible return

Recommended Posts

Well considering last night I bought a cheap Jebao to mess with a couple of ideas I got. So I decided to design a simple system on my cad program. Now just waiting for the stuff to arrive this will be another slow build probably won't be officially up until next year due to possibly having a flight for work a couple of month from now and it being a bit of a long trip to long to leave it in the care of someone else. But I figure I would start a thread to have people suggest any tips or possible problems they see in the system. The tank is around half a gallon as I always wanted a sub gallon pico and my first attempt was a horrible failure as the bulkhead design I did was loud as all hell to the point that I had to take it down because I could not stand the noise. The cabinet is a small IKEA cabinet which will house a freshwater (1/3 of the capacity)and saltwater(2/3 of the capacity) container and the Jebao that is all.

Flow pump will either be a custom magnetic coupling based or a cheap 52gph one I already have.

Float sensor.

Freshwater and saltwater container

Rock:
BRS dry live rock
Substrate:
Mame sand I have laying around

Bought my 2nd reef related thing in years. A small madison float switch looks butt ugly(brown color) but it is the smallest I could find.

5/22/2020 switch arrived even tho the color is ugly I will admit it is quite small.

Noticed I haven't posted my other equipment. The nanobox frame, diametric magnets, new motor to test because the old one was too powerful, and the dual propeller design for flow. The API bottle is for size comparison.

Noticed people putting ketchup in their tank so I did the same

No problem^^ So today I was surprised with a set of diamond bit and didn't really have any slim glass pieces to test them out so the tank was a test piece and this happens. Doesn't really affect my plans I can just 3d print a bulkhead for the PVC to insert the doser tubing but there is something funny about seeing half a gallon with a 3/4 drain. My regret is not drilling it on the other side.

Flow is good tho a little to good

If anyone is wondering glass thickness is 3.80mm or 1/7 of an inch.

Well got a refund for the dosing pump I bought on eBay 80 something since I bought it and still hasn't shown up so plans had to be adjusted, started tinkering with the idea of all in one so I did this basic design. The hole in the center is for a 1/2 inch bulkhead for drainage if I decide to do awc. I will probably 3d print it that is why it is shown cut in half even tho my 3d printer is big enough to handle it together I feel splitting it will give a better result and I will just epoxy the 2 half together.

I'm excited to see how that diy pump does for flow.

Magnetic coupling based pump are actually very simple the only real issue is the mount design as it needs to be a low friction a simple ceramic shaft is always an option and so are more expensive ceramic ball bearing. I just haven't gotten around to 3d print the new mount for the new motor to test the flow. But now that the plans have changed to aio thanks to shady eBay seller I may not even need it the return pump may be already too much since it is half a gallon after all.

So a little update I managed to get a Mame ato for a good price, so I readjusted my design once again to allow for it to be mounted. The 3/4 drain is connected to a 3d printed cube with 2 other hole one is for the awc and the other one is the drain which will have will send water back to the tank with the 1/2 return it has. The cube also has enough space for a 2nd float switch.

 An inside look the bottom bulkhead is for the awc it will have a tube inside to

match the display area water line and the one on the side is the drain for the return
