    Hello! I just started into this aquaponics thing and started off with a small growbed. Got the bell siphon going and everything works!
    Except that it drains down to the last inch of water and just stop filling the bed. So the water never drains comepletely. (Not sure if theres suppose to be leftover water all the time?)
    I can hear the siphon continuously suck up the water at the last inch so whatever water pumps into the bed is already sucked, so the bed doesn't fill... I'm so confused what I did wrong, please help!

    Welcome to the forum!

    Having leftover water in the bottom of the bed is fine, in fact most media growbeds are designed to have a layer at the bottom permanently flooded. No worries there! It sounds like your water flow into the bed is too fast for your siphon to 'break' (stop siphoning). If your pump can be turned down, try that; if it's not adjustable, get a T piece and split the flow so that some goes to the growbed and some goes back to your tank.

    What's your setup? If you post a diagram or some pictures we can probably give more detailed advice! :thumbsup2:

    Hey Lock_Chan, I got a notification that you'd replied to this thread but the forum was down when I checked, and now there's no new post from you - I think it got lost. o_O

    Oh! How weird. o_O well thanks for your advice! I'm definitely gonna get a t piece since I can't control the water flow.
    My setup is an ibc tank with my turtle and goldfish living in it. (Preparing for the green stuff to hit...>_<)
    the grow bed is an underbed storage with river pebbles and a bell siphon I made just like Robbob's from YouTube. I plan to have a a bigger bed once I'm confident enough.
    Unfortunately the site won't let me post links for my photo. D:

    Oh cool, RobBob's channel is an awesome resource. :D I've used a bunch of stuff I learned from him in my system-in-progress!

    If putting the T in doesn't bring the flow down enough, you can add a tap on the branch going to the growbed to get more control. For pictures, you can upload one directly - it has to be reasonably small, so you'll have to resize it - or you can link from Photobucket.

    A tap on the branch? Does that go over the top piece or the tube?

    Sorry, I wasn't clear - I meant an inline tap, like the ones that get used in irrigation systems. A lot of them have barb fittings, so you can just push them into the end of your pipe to get better control of the water flow. Like this one: https://www.bunnings.com.au/pope-19mm-poly-inline-barbed-tap_p3129110

    (It's always best to use plastic fittings instead of metal in an aquaponic system, it's safer for both you and the fish!)
