    Hi Fellow planters
    Here is a pic of a unit I made for a customer for automating water changes.
    This is a normal washing machine 220v solenoid that can be connected to pumps or water supply.
    one can connect a float switch which controls this unit which will automatically fill your aquarium. The unit needs modification, if you have friends in the engineering side like I do, they can machine parts that can be mounted inside a box an adapt the exit to accommodate a pipe.
    Just another crazy idea, i had, i enjoy making gadgets.

    Fixed the image link for you.

    Image tags were correct, just the link that didn't load.

    I've always loved the idea of automated waterchanging. The thing is, I'm rather terrified of the tap water in centurion. If you fill a glass out of the tap, within 10 to 15 seconds you can barely see through it because of all the tiny white bubbles that come out of the water. They are so dense it looks as though milk has been mixed in to the water.

    What would you suggest in places where tap water is really bad Phillip?

    I suggest you connect to water purifying units in tandem,1 x 1micron prefilter and another with a carbon block.
    The units are not expensive. the cannisters look like the r/o type,but the clear.your cartridges are cheap, 1 micron R 45.00 and the carbon R 150.00.
    Going the R/O route is too costly, the amount of water wasted via this system is great. 2:1
    let me know if further assisstance is required, will gladly assist.

    the bubbles you see floating around are CO2. they will disapear after awhile.if you shake a jam jar with the newly tapped water inside, it will dissapate even quicker than just leaving it for a couple of hours.using water from the tap (as long as the parameters are ok) you should see your plants pearl more than normal after a couple of minutes.you could test this by using a pH test.the pH should raise slightly after the CO2 has left the water.
