I'm setting up a easy and extremely cheap auto water change. It takes no dossers or any of that equipment.
This is the stuff that is needed:
1/2" Drill 15$
2x 1/2' OD bulk head 1$
10 or more gallon toat 10$
2x 1/2" Tube adapters 1$
1/2" OD Rubber Tubing 5$
1 Internal pump anything above 50GPH Depending Used or not 10-50$
Any stop watch Assuming you have one
Some Egg crate 3$
Zipties 2$
Outlet timer that goes down to seconds 20$
Drip Auto top off 10$
How:
You need to find out what height in your sump is 10 gallons so use the equation: LxWx"X"/231=10, If I plug my sump dimensions into the equation I get 7 inches. My water level is at 10 inches so when I get the pump I will make a 3 inch stand and stand the pump upside down onto of it. So it can't suck a overly large amount of water the timer is used to make sure you don't get over 10 gallons as the sump refills from the DT. So get a stop watch put pump in a bucket of water and time how long it takes to fill 5 gallons. Take that number and double it, set you outlet timer at that amount. Set the timer to repeat this at any time that suits you, I am going to do this every week.
Next, setup your toat some were above the sump and hook up the bulk heads to the bottom of the toat and have it run into the hole you drilled in the sump
with the Auto top off installed.
How it works:
So when the timer hits it will drain for the amount of time you have it to go pumping 10 gallons out of the sump. These 10 gallons are then replaced by fresh saltwater from the Auto Top off.
It only cost me 65$ Were some other designs use 2x dossers witch range from 50$-150$ each.
