A place to discuss aquaponics

wow check out those tommies on the home page

FF: Fancy that, me and aeldric were at gardenworld today, and I bought some smartvalves... Did you see any geriatrics whilst you were there?

Steve is your pump on a timer, or continuous flow. I can't get my head around using autosiphon's rather than EB's method without having a smaller pump on continuous flow?

A better approach might be to use a float switch (I made one using a piece of suitably carved PS foam and a mercury tilt switch) and relay to turn a pump on whenever the top tank isn't full.

Asitis, yep, i have comapratively small pump (35W) running 24/7

Mecury tilt switch next to fish tank? I once broke a thermometer (mecury) and found the mecury a year latter when I changed out the carpet. Icky stuff.

mmm, not the best option

A safer alternative is to by a "reed switch" from an electronics place like jaycar, they are actually smaller than a mercury switch and all you have to so is incorporate a small magnet into your "float on a rod"

If you found the mercury a year later, it doesn't seem so bad.

what about the float setup out of a dunny.am sure they are readily available secondhand

Except that kids sitting on the carpet may have been in direct contact with mercury

Mmmmm! Murcury poisoning!

yeh, i can remember pushing pretty little balls of mercury around the kitchen floor when i broke the thermometer as a kid...............explains why i'm mad as a hatter

CHANGE PLACES!!!!!!
