ATO with Profilux

GHL Mitras LX7 Club
Hey everyone, I am looking to setup an ATO system for my tank. Since I already have the Profilux, I figured that I may save some money by buying some GHL pieces to setup an ATO device. Exactly what do I need to setup an ATO setup and to make sure that I am as safe as possible from potential sump overflows?

To quickly describe my setup, I have a 29g sump and plan to use a 5g bucket as the RO reservoir which will be right next to the tank stand.

Thanks
 
Depends on how far is your source of RO\DI water?
3 options

1st get a 3 dosing pump, to pump fresh RO\DI from your reservoir. That way you will also be able to do automatic water change as well, Really sweet!

2nd Get a regular pump an put it in the reservoir and set a socket to be configure to ATO

3rd you could get a NOrmally close selonoid valve hooked to your RO\DI unit and cofigure it the same as #2
 
The 5g bucket will be 1ft from the sump and will be replaced with a new 5g bucket of fresh RO water as needed. If I use an Aqualifter pump would that work for bringing the water from the bucket to the sump and not cause a backsiphon? Would the solenoid valve have to be connected somewhere on the pump's feed lines?
 
My selonoid is conneted to the output of my RO/DI unit, when the level of the sump gets low, the profilux energized the selonoid (open the valve) of the freshwater output of my RO/DI Unit! My sump and my RO/DI are close together!
 
I use a 5G water jug and a Tom aqualifter... it is connected by a optical sensor and it works like a charm...
 
Maybe that's what I'll do. Use an AquaLifter since I have one that's lying around somewhere.

Would it be possible to have 2 float sensors just in case the first fails or is that highly unlikely with the GHL ones? If I wanted to have a backup float sensor would I just need the Y-Splitter and the second sensor?

Also, which sensor is more reliable, the float sensor or the optical sensor?
 
I still dont have mine setup but I will be running 2 optical one in my display and one in my sump.... I will run a floating as a backup in my sump as a fail safe...

So on my Ex I will have one of the optical and one optical and one floating to the main unit using the Y floater splitter...

They both have their down side, the optical will require some cleaning every now and then (coraline and algea) and the mechanical might get stuck (happened to me small piece of rock on the shaft prevented the movement)
 
Yes a splitter is all you need for 2 floats or optical sensors.
They both need cleaning. I like the floats myself. If it gets stuck its usually stuck in the off position, and if it happenes the other way the timeover safety catches it.
I clean my float every 2-3 weeks by making sure salt creep is washed away and is free of obstructions.
I just use a maxijet 900 set up on a outlet for top off feed pump.
 
Another question, if I buy the GHL Water Level Sensor Bar are the fasteners included?

I just realized that I don't have an available outlet on the powerbar, I guess I'll have to buy a 4-outlet powerbar.
 
No they are not you need to order a PL-LF-Base and a PL-LF-S*

* relates to whether you get an optical or float sensor
 
If you are using a tom's aqualifter you can get away without even using a controller. Just put a good quality airline valve on the output line in your sump from the aqualifter. (keep it above the water line). Then you just have to set the drip rate to match your evaporation rate. This can fluctuate based on your location & season but it should need fairly minimal adjusting.

Of course using a controller is fancier... but this would get the job done.
 
I would spend the extra money on the 6 outlet digital power bar if I had it. IMO, for just 2 more outlets the price significantly goes up, what makes the 6 outlet powerbar worth it as oppose to the 4 outlet powerbar? Convince me and I may get the 6 outlet instead. :D
 
You can daisy chain it saving the use of an additional port and you can also add the dosing pump station to the daisy chain.
 
Michael, covered pretty much all of it :c)

I'm saving for one right now... I know it's more but it's also more flexible... you never know what the future will bring on that will connect to these... plus you get 2 extra socket :c)
 
Well, it looks like coming up with the extra money is going to be difficult. It will be at least another month or two before I can have enough money. One question though, if I have another 6 outlet connected to the first 6 outlet powerbar, do both these powerbars share the amp load and use the second's 15amp if needed?
 
Each powerbar will have their own 15 amp max, but obviously need to be plugged on a different electrical circuit!
 
Remember that it's only "sharing" the control line... the power source could be any wall receptacles in you’re house... or close to :c)

So if you connect it to a separate 15amp breaker line it will be able to supply a extra 15amp..
