ATO from autotopoff.com

I got no pics of this one but a float switch from chicago sensors and am currently using a toms aqualifter into a 2.3 gallon resvior,(carribsea Sw with RO water in it), modded extention cord retro'd for the floatswitch to tie right into it and it works just fine. I fill that jug about once a week along with a 5g water jug for my 2 weekely water changes. It cost about 20 bucks since the aqulifter was a freebie and the airline tubing is like around 2 bucks. I'm all about ghetto cheap but keeping it looking pimp.

Okay, you're half way there .

Your next job is to remove the metal balls inside the metal tube. I used a cut-off wheel to remove 1/8" of the metal off the tube end. They should then fall right out.

Next, you'll need to position the bottle tube end at your optimum tank level so that the tube end is just barely fully submerged (like in the pic of the experiment above). From there it will automatically gurgle fresh water into the tank when evaporation occurs until the tube end is covered again by water.

thanks so much
i just did it
exept for the cutter wheel
i used pliers to widen the end
but it works!!!
thanks

I used a GHL optical switch connected to a Profilux Plus II

wow
fancy lol

Great! I'd like to see how this works out for you when you've got it set up on the tank.

I top off with water....wet water.

ill post pics when camera is fixed
lol

hey xenon,
have you had any trouble with the peristaltic tubing with the more caustic stuff (kalk, etc.)?

do you have a closeup pic and link for the optical switch? tyia

I just set this controller up a few days ago and have been testing to see if kalk can keep up with my calcium/alkalinity demands. It turns out it cannot so I will be dosing with 2-part recipe #1 from now on and top-off with ro/di.

I don’t have a close-up of the optical sensor.

By hand before i go to school and when i get home. i dont mind it no need for a system

JBJ ATO system with backup control by RKE. RKE float sensors monitor high and low levels in the sump while the JBJ monitors low water in the ATO reservoir and the sump. If the RKE float sensor's trip then either the return pump shuts off (low water in sump) or the JBJ is shut off (high water in the sump).

Think of it as being from the department of the redundancy department.

By hand. I need a budget ATO

If you have a skimmer that need to be at a specific water level to function properly you must have an ATO. I am blown away how productive my skimmer has been since adding my controller.

Budget ATO

Gallon plastic bottle with 2 holes in the lid. One tube goes to the bottom of the bottle. One goes in 1/2"
Air pump
Digital timer

This makes it possible to be away from home for more than a couple of days without worrying about the water levels.

Tunze osmolator pushing water threw a kalk reactor.

Every day I check the salinity with a hydrometer I top of my water with fresh RO water as it needs to be. Some days I get more evaporation then others.

Used to have a Auto top up but since I added a fuge and found it less reliable when two tanks are in the system as if I need to adjust the pump and normally do after a water change, the level slightly alters and if I forget and put my hands in the fuge lots of water goes down the overflow and changes it again.

So decided to use it as a safety cut off for the pump in case of a overflow block it will turn the pump off. I now check the SG every night before bed which has accually been eaiser as after a water change I no longer need worry about the exact water level. All I need to do is make sure the SG is right each night and before the water change.
