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!
