show me your ato setups
 

hi there everyone
looking at building a ATO for my frag system
i am thinking a gravity fed type thing
anyone got pics of there setups ?

You can usually find decent deals on used Tunze Osmolators which is what I did. No DIY (possibly cheaper) and it's rock-solid so far.

I use Tunzes on all of my tanks and have never had an issue.

I just gravity feed into a float valve. Simple and rock solid. Many people fear that a float valve will "fail", but float valves are used in household humidifier systems under household water pressure. We don't even come close to the pressure our tap provides in our aquariums. You can take a look at my build thread for pics.

Furnace humidifier float valve connected to ro/di. Was planning on getting a storage tank and place it between the floor joists to gravity feed it but works fine as is.

That works well too. I like topping off from a small reservoir because I know I can only ever dump 20 gallons into my system if something does fail. That might wipe things out too though I suppose!

i like the humidifier float valve idea
where did you find that!
i need to find a way to install it with out drilling holes or silicone due to the tank is running now

i used pvc primer and glue to mount my float (BRS model) to the side of my emergency overflow pipe which is also pvc. Works great if you have a way of mounting a piece of pipe (have bulkhead).

Valve was from Home Depot. No drilling to the tank, just a piece of plexi with a slot so could adjust valve height, then siliconed into the corner of the sump.

I've got the same home depot humidifier float valve for the ATO on my nanos ghetto sump. The valve is gravity fed from an empty salt bucket filled with RO/DI water weekly.
