Automatic Water Change System

[d3adlydesignz]

So with a lack of being able to do water changes all the time when I wanted/needed to. I have decided to go about a automatic water change system. The way the system works is I have 3 tanks. 1 75 gallon, 1 100 gallon, 1 150 gallon. Each pump has a submersible pump that's on a weekly timer. I can set the day/s I want the pump to turn on as well as the time I want it to turn off. Then to refill the tanks I have a float valve in each tank. Once the float vale drops past the set position the water automatically refills itself.

Also the pumps in each tank are different flow rates. Due to having 3 different sized tanks and only one timer.

Here is my calculation

75 Gallon
180 GPH = 3GPM x 8 mins on = 24 Gallons = 32% of the water

100 Gallon
240 GPH = 4 GPM x 8 mins on = 32 gallons = 32% of the water

150 Gallon
317GPH = 5.28 GPM x 8 mins on = 42.2 gallons = 28% of the water

NOTE: The darker photo is when I officially ran my lines. The first ones are just s trial fitting..

Hello; How do you deal with source water chemicals such as chlorine/ chloramines?

I honestly don't have any issues with my water. Its well water and for months never added anything. Lately I just add stress coat for the metals. I just go down when water change is in process's. Or after it and add as needed.

brilliant idea I also use automatic timers for my indoor tanks. I have the new water pretreated and ready in buckets behind the aquariums and I just run the pipes into with old water down the sink in the basement.

Nice! Yeah mine is in the basement so I decided to this. I'm waiting on 2 pumps and 2 float valves. Once these come in I'll post a video of the entire setup.

Bump?

Not trying to bash this idea but, how is this easier or better to setup than a constant drip system? It seems like you're really counting on the float switches not to malfunction and, if they do, there is no emergency overflow to allow the water to be directed outside or to a drain.

Hello; this would be a concern on a wood floor. In a basement with a drain not so much.

So as soon as the pump comes on and starts to drain the tank the float valve lowers and start to try to refill the tank? So is it possible that you are also removing some of the new water with the old?
