Auto water change setup?

[elzool]

Sorry I bought this guys. Sorry for you, not me, I love it, even if I cannot figure it out on my own. :)

I'd like to automatically change 2 gallons of water every day.

Socket Function S1 - Dosing Pump 1
Socket Function S2 - Dosing Pump 2

At Dosing Pumps I have the same settings for both 1 & 2.
Flowrate 60, Rate/dosing 400, Dosings/day 19

How do I get this to start?
What did I do wrong here?

[elzool]

Weird... it just started the change. Took about 20 minutes from saving it. I just thought it would be immediate after saving.

Nevermind.

Thanks!

Ok we are now heading into areas not even i have tried to program!

As far as i can tell you will have to program and event timer function to this socket

I will get Matthias to take over from there. But will have a look myself also

[elzool]

The settings I had make it work. It just didn't start immediately after clicking Save which I had expected it to.

Everything is fine now. Thanks!

Hey Richard,
Why do you have flow/rate set for 400.. ?\

This is my next step:)) Water changes....:)

All working, panic over - Back to bed!:o

[elzool]

Mike,
400 ml dosed 19 times a day equals 2 gallons. So I put 2 in a day and take 2 out a day. Maybe there is a better, more scientific way I should be doing this, but that's just what I started with. I suppose I could do a higher ml dosing a day and dose less often to equal the same amount. I asked FishieNut what he is doing via PM, maybe he'll chime in here as well.

Sorry to wake you Michael. ;)

[MSHUR]

Ahhh...Got ya..:)

I think 2 g a day is good. Of cause it depends how many g tank you have. Good luck with new fiture..

I figured with a 75 gallon tank changing out 14 gallons a week is pretty good. I'll just keep on top of my testing and see where it comes out the first few months. :)

[Fishie Nut]

I pm you.
I have mine set with the four dosing channels on sockets 1-4,then I have the analog powerbar set at 5 through 8, the the doser is daisy chained to the digital power, which is set at 9 through 14.
I have 900 ml as the rate and I have it set at 12 time per day.

The doser starts whenever it feels like it, but it will dose the amount the number of doses you set during a 24 hour period. It's like got a mind of it's own... LOL.

[elzool]

you can say that again ;)

I tried for an hour tonight in the rain to shove the ro tubing up through some existing tubing that runs from my s/w and top-off cans to my sump. After an hour I gave up as it kept getting stuck about 12' from the end. Apparently when it's raining I have no patience.

I'll put it through in the am if it's not raining and then fire it all up and measure my flow rate per minute.

Then I'll be set.

Hey Fishie, did you happen to measure your flow rate per minute and if so, were they right at 60?

[Fishie Nut]

You know, I didn't measure, but I have a 50 gallon reservior container and I mix salt every other Sunday, so that about right.

I figure 100 gallons a month on a 300 gallon system is pretty good. If it's +/- a few gallons, no matter.

True. My only concern would be that one pump was pumping a dramatically different amount that another pump increasing or decreasing the salinity a significant amount.

[Fishie Nut]

As you say, True.

I check my salinity every once in a while and it's pretty steady. Moves up somewhat, probably from salt creep. Actually I have my Saltwater Out a little more than my Saltwater In, and the ATO will dilute the water a little and it keeps it pretty steady at 1.026.

Now you've got me spending more money for the conductivity interface/probe... LOL.

[elzool]

Hey, if I *have* to buy one, then you do too!

:D

[elzool]

Measured my flow rate/min last night.

Pump 2 (Saltwater In) 45ml/min
Pump 4 (Saltwater Out) 50 ml/min

The incoming saltwater travels out of its holding can about 15 foot up, then 20 foot across and then 15 foot down. Give or take a foot.

The saltwater is output about 4 foot away from the sump.

Measured each line three times using the same equipment with the same results each time, so at least it is consistent.

Now I just need a bigger SW mixing container.

I sure love this gear. :D

Thanks Matthias!

[Matthias Gross]

...and therefore you can tell ProfiLux the "real" flow rate. Did you change it according to your research? Then ProfiLux is able to calculate the on/off times precisely.

[elzool]

Yes, I changed it to the actual measurements.

My biggest problem in setting up the dosing pumps wasn't with the pumps or your equipment at all. It was in finding an accurate enough measuring device to measure the flow. Took a few minutes but then I found a beaker that was graduated in 2ml increments.

Thanks again!

[Chrisrush]

Very nice research Richard. I'll have to do something similar when I get my dosing pumps setup. Did you just use a normal stop watch and a graduated cylinder?

[elzool]

That is exactly what I did.

I think if my holding container wasn't so far away up,down and across I wouldn't have been as curious about it. But having done it, it really takes just a few minutes and then you know it's accurate.

[Chrisrush]

That's the same situation that I'm in. Both my water change container and drain are in the laundry room, some feet away.

[Matthias Gross]

There is another way to measure the flow rate:
Use your kitchen scales!
First weigh your container.
Then fill it for exactly one minute with the dosing pump (you can press the red button).
After that weigh again your container.
Now you know the amount in one minute (assuming that 1l = 1kg is exact enough).

[elzool]

You know Matthias, I wondered about weighing it, but I had the cylinder out already.

Does 1l=1kg for fresh water or for saltwater or is there a difference in weight?

[Chrisrush]

I'm not even sure I have a kitchen scale nor a graduated cylinder, but I know I can get a graduated cylinder at work easier than I can a scale.
