so...
i had this idea for a new kind of water pump. Don't know if this is the best place to post this though....
any way here's my idea.
Remember, i know it'll sound crazy....
Take your fish tank. Make it a bottom drilled tank, with the refugium and other goodies underneath. Then off the refugium make a special tank.
This tank has a single hole on one side near the bottom of the tank, so this tank will always act as a reservoir that can be drained if th water in the refugium or sump is low.
Then take and place an under gravel filter in this tank. Put a layer of crushed coral down, but then cover over with a layer of Silica Sand.
In Place of the standard plastic tube on the undergravel filter use a glass tube.
now for the craziness.
Take an electrical cord. Add a adaptor so your putting DC current through this 'pump'. take the positive wire and soder a capaciter to it. make sure this capacitor is no where near the water....
Then some where after you've done this take a graphite disc. solder to positive end, below the capacitor.
next step on negative end solder a thin graphite rod.
put the disc at the bottom of the undergravel filter, just as if it were an air hose.
basically this would act as a Ionic breeze for your fish tank, but only in the small reservoir...
If you used an adjustable capacitor and experimented with some resistors, you may even be able to get a water pump that doesn't put the water through electrolysis, but is still capable of breaking down certain harmful chemicals (sulfides, and such.)
any way....
just a bit of craziness. seriously though don't try it with fish....
