Reef Aquarium (Auto Water Change) using DIY Controller & Custom Sump.

Video of Custom [DIY Ardino based Aquarium Controller] running AUTOMATIC Water Change, using Measuring Section/Compartment of a Custom Built Sump, for a 65 Gallon Aquarium.

All the [Aquarium/Controller] details are here on this [Tank Thread].
A video of the [Sump/Build] and test is here.

The [SUMP] running when originally installed here.

The Controller was built primarily as a Custom Doser, but kept adding more feature and Functinality to make it Multi-Purpose.

Here is the [DOSER Test Run]

Pardon the SHAKY VIDEO PARTS, I had no help running demo and filming.
Plus had only one shot to catch the test, so filmed it from START to FINISH to give idea of timing (Thus no editing).

Whoa this is some serious DIY! Nice work.

Got the Auto-Station Area Setup. (Here is a picture. When I'm completely done I do a New Video of Everything working)

Still have to do the doser lines.
I went small bins (FILL/DRAIN) to handle a months of weekly water changes.
Eventually I'll integrate a Large Salt Water Mix and Auto Drain into a nearby House Drain (for Total Automation)

If you want all the detail with ongoing updates...
Evertthing in in this Tank Thread.
