A place to discuss aquaponics

I selected this pump based on GPH,affordability and efficiency (only 8 watts).I want to use it with a 30 gal. system!

depends on the head you have to push (measured from the water surface up to your height) its best to run a slightly larger pump with less load on it than max load on a small pump.

The pump claims 90 gph @ 3' head, I don't think I need to lift any more than that.I may consider the next size up!

I've tinkered with some of these tiny pumps. It would probably work but won't give you much room for expansion.

It may or may not give you enough flow to use a timer and you will be working with small tubing if you try to go with auto siphons so you may find getting everything flowing just right to be a bit fiddly.

Here is another option, it is the pump I have running my aquarium system, my quarantine wing, and even one running my solar heater even though I suspect the hot water isn't good for it. I have even tested one out to run the barrel ponics system and it is capable of pumping enough water up about 6' for that system.

And it is fish safe. Hooks up to 1/2" threaded fittings easy enough.
