Home made aquarium auto top off

Two float switches detect when water in the sump or refugium is low. Activates a pump to refill to the proper level. If the upper float switch fails, there is a third backup float switch which shuts down the entire device from working and sounds an alarm until the lower two float switches are checked. Has a push button to bypass and manual fill the sump. Has a main power switch and a switch to turn of the speaker. Not added yet is a fourth switch in the fresh water reservoir which when the water supply is low, will also shut down everything and sound an alarm. See my other video ATO tour.

Updates, this is a great system that my tank needs.

@GroinStabbingPro Someday I'll get around to making a kit of some sort.

Any update on this project? It's been quite a while.

@bbalak Sorry, as you can see from my other videos, the RC boat is my priority and is a long slow build since I have to make EVERYTHING myself. I'm always thinking I want to get back and make a semi-kit of this ATO. My intentions are still there, just don't know when, but since this one I came up with new ideas I want to add to it.

Sweet DIY !!!!!!

@vavoomskill Thanks. It was not easy. Many hours to design it.

@toxicfrost123 This is designed to use 120vac and 12vdc. The 120vac powers the pump through a relay and also powers the circuit board with 12dc from a small brick type power supply.

@rashiidefukazumi The pump is AC, it is connected to one of the outlets on the ATO. It's an Aqua Lifter AQ-20 pump. Low current draw type pump.

@varmman I'd like to find a better sound, but the point of the annoying sound is to notify me that something is wrong, either a float switch is stuck or the fresh water supply is empty. It works, and it sucks when it goes off at 2am. Needs a timer to work during non-sleeping hours.

[varmman]

That sound gonna annoy your fish! anyway,this is brillian though

[rashiidefukazumi]

btw the pump is AC or DC supply??

[toxicfrost123]

can i run this of a 12v or do i need to use a relay?
