automatic water change

Yea thats the one so 4% loss on a daily vs once a month...so that *could* get significant at hourly perhaps...

That was more of a comparison between a removal then replacement water change compared to a simultaneous change like is bring done with these pumps.

Right, so does the rate matter though? I found this link which kind of implies that it doesnt...

Too bad I don't know how to do differential equations. I blame my Jr high school guidance counselor for putting me in the wrong math class in 8th grade.

Then I found this article which I'd read before where the guy is using a litermeter which changes 150x over 24 hours!

So, does rate matter? Or is the loss of efficiency just between bulk replacement and small batch/continuous?
 
Rest of the Diagam as promised :)


This is why I'll be using a ReefAngel lol. I can't even begin to critique, but I'll say that it looks awesome. I will be referencing it a lot as I have a lot of wiring still to share the 24V power supply with the two relays I'm using, the solenoid valve and the pump.
 
Well, I made an offer of $85 on the lot of 4 120v pumps ($100 shipped) and they took it. So, I guess we'll see how they work for this setup, pretty excited to get them into my setup.
 
Should be easier to hookup, but you can't control those AC pumps like we're doing with the DC ones.

And yea, isn't that little tiny 5 dollar board the best zachts lol. Like I said, I like this better then a fixed rate stenner with how quiet and adjustable it can become. I've also been using mine for aclimating stuff as well too. I programmed in an override in my apex and just put the waste water line into a bucket

:) but what could be easier than flipping a switch and programming a lamp timer, LOL! It's pretty bad though once I start planning these projects I just have a terrible time settling on what will actually be built, I'm already tossing around improvements and what if's for how I may want to use the system and how to make that possible from the start..........

But let me know if you have questions, If you do something similar in function you basically just replace the lamp timer and switch with the Reef Angel otherwise very much the same.

Now that is a fantastic Idea! I might never have thought of that, just like I never thought of this pump setup until stumbling at random on this tread. If I ever finish this build I've saved tons of time and cleared out a large section of my basement that was once full of mixing buckets and boxes of half used salt. I can then use this new found time to start a new project instead of finishing all the other projects that I should be focusing on......
 
yea, and the override still works with the safeties just in case you leave it on. I've got a few virtual switches for stuff like that in my program so that the actual outlet or variable speed port does not have to be taken out of automatic

So do you throw a float in the acclimation bucket to keep it from over flowing and shut things off if you walk a way for too long?
 
The acclimation is on a max timer (2 hours) so no float, and then locks out for good after that. I've never gotten remotely close as I normally do it in a 5 gallon bucket, which would actually take 10 hours at running non stop to fill it up. It's also nice because as you're pulling water out of your tank to bring the levels from the shipping or QT water to your tank levels, you're also doing a small water change :)

However with all that, and leaving it in auto, you're still protected if you run low on NSW during it or something like that. I need to play with the programming some more but I'm also going to set it up to where if I call for top off too much to shut it off as a safety too, and try and set something up in reverse too like a normal top off window and then not seeing it to alert me I may be putting too much water back in.
 
Acclimation is perfect and goes along with my idea of having the qt tank setup. I can move the fill/drain from the 10g to the specimen container and sit that in a 5g bucket. Basically doing a water change on the pet store water. Love this idea!!!
 
I don't know if I'd put any of my lines into their water at all lol. I have a small 1/4" hole in the side of the bucket and i let the line drop into it.

It's about the only time I've had to carry a bucket of water since I installed this since anything from a LFS or my QT goes down the drain :)
 
anyone have a suggestion on what tubing to use on the heads, and beyond?

Depends on the size of the pump tubing. those ones you ordered look like they probably use 1/8 inner diameter tube, (ie. air line tubing roughly) If that is the case the fittings I'm using will work nice. You'll have to wait and see when they arrive.
