refugium\sump from my bigass sump I took out has resulted in the need
for such a device.
I'm looking for a very basic system, gravity\siphon-fed. I can
build\fabricate most components myself, and have tubing, acrylic and
many other materials on hand.

I wanted the same thing without spending much money .

What I have is two plastic five gallon gasoline containers (they never had
gas in them) I put rigid tubing in each one with a little bit of the tube
sticking out of a hole I made in the top of them. These tubes go all the way
to the bottom of the tank I then put a lot of silicone at the hole to make
it air tight. Another rigid tube goes into the vent hole of each tank, again
I made the holes air tight with silicone. Then I tok an old air pump that I
had and connected it to one of the riged tubes with standard airline tubing.
and connect one container to the other in the same way. connect the air pump
to a timer and voila.
What happens is that the airpump will pressurize the gasoline container and
send water up the airline into your tank for a set amount of time. By
regulating the time that the timer is on, you can reguate how much water is
added daily. Just make sure that the end of the tube is dripping into your
tank and is not actually in the water, otherwise when it turns off the tank
water will siphon back into the casoline containers. This also works for
watering plants etc.

you can use this siphon effect to make an autotopoff without any switches or
floats.

needed:

5 gallon water bottle
plastic waste paper basket
1/2" tubing
small pieces of 2x4 used to make a stand for the waste basket
water crock spigot
small hose clamp

drill hole in side of basket near the bottom
insert spigot
using clamp, fasten hose on spigot
fill basket with water
insert end of hose in sump under water
lift basket until siphon starts
find the correct height of water such that the height of water in the basket
is about 1/2 way
using the wood, make a stand to hold the basket at that height
invert the 5 gallon jug in the basket

when the water level in the sump drops, it will suck water from the basket
through the siphon. when the water level of the system drops enough, the
water will come out of the jug to replace it.

note: turn off the power and watch what happens to the water level in the
basket. ensure it won't overflow.

It's the simpliest possible (this bottle)

I have to agree!

I use kalkwasser in this, but have been told, it mix with water in tank
sooner than it drips to tank. Is it true?
Marx

I would imagine the most concentrated part would pour out the bottle first, and
a weaker solution would drip out as it is needed.

Something like diffusion?
Kalkwasser is well mixed, so there is no more or less concetrated part
in bottle.
