Once your dosing enough two part, you wouldn't need the valve anymore either.

Basically what I did today was run it with just water for 1 minute into a small measuring container, adjusting the valve until it puts out the amount I want in that minute. Got it to xx ml per minute and will have it turn on every 2 hours to dose this small amount throughout the day. Alternating alk and ca. So one hour is alk and then the next is ca.

I would be really careful with these pumps though and check them every once in a while. I use one for my ATO and it sometimes doesn't turn on when its suppose to.

They are not designed to do this really but we'll see how it goes.

They are great for a cheap ATO. Just need to get a float, splice the wires into one side of the aqualifter power cord. When the float drops to the bottom, it restores the circuit and turns the pump on, once the float rises, the pump shuts off. Im sure most people here know this but for those who don't (I heard ATO being mentioned before). It cost about $25 to do.

I wouldn't use the aqualifter for Kalk...I think it would clog up pretty fast. Even with two part, I would imagine the pump needs to be cleaned out with vinegar a few times a year to keep it running properly.

OK, Thx, I got timers that can run Miliseconds

That's great then. Makes everything even easier and less chance for things to clog or go wrong.

Can I ask where you got them?

MMMM Pumping of jugs.

What? All I said was "Pumping of jugs." We are still talking about dosing right?!

In a futile attempt to reclaim my honour now (I realize that ship has sailed long ago, I may as well ask for my hair to grow back, but I digress), I'll add to this that I held off doing the Aqualifter pump dosing for the longest time because I was *certain* I would need timers that could do sub-minute intervals. In the end though that was a moot concern: in fact I'll probably switch the durations to two minutes per cycle because I'm having trouble keeping my Ca steady for some reason (just keeps dropping and dropping).

Plus, if the fluid is being pushed up a foot or two, it almost is only a drip. My ATO is a few feet and its a steady drip without a valve.

I knew that would come up. I'm serious though! What is all this talk of jugs and the pumping of those jugs?

Siemens LOGO's bacically, a little PLC. Has inputs, controllable output relays, and a host of functions, timers, counters, even analog possibilities for temp controll too. I get them off Ebay. If your looking, look at the last 4 numbers of the model eg OBA0-OBA6 OBA6 is most current, and OBA0 is the originals. the amount of functions and possibilities increase with each model. Like the OBA0 cant have any Analog, I dont think that came into effect untill the 4 series. Have to watch the letters after too, some dont have internal clocks in them. You want a RC in the name, like Logo 230 RC along with the model number

search ebay, some can be found cheap. They even have a little LCD display that works with the OBA6. called the Logo! TD

All part of my master controller plan. presently I have a few OBA0's one doing lights on the 150g, another handeling ATO duties fro both tanks and the 3rd as spare. Programing is easy too, all Block Function logic. mostly Boolean with some premade functions. The PC programming software, LogoSoftComfort is real easy to use, even has a simulate function so you can test without plugging into the unit itself.
