Air Pump or water pump
5:28 am in How-Tos, kits by Herman Widodo
I just start building my windowsfarm.
Can I use water pump rather than the air pump ?
I found that aquarium water filter pump that lot cheaper than the air pump, and might be easier to build the water flow.
Thanks

V1 instructions used a water pump, but they found that too many of them failed. The nutrients clog the motors and they don’t typically last as long.
That being said, I do find they are more reliable for delivering water then the airlift design in V2 and V3. But I would recommend looking into what is being called the “T-lift” method in some of the older posts.
I agree, T-lift is key and you can run it all with a $9 aquarium pump (I have mine pushing water up 12 feet).
have a look at http://quasar28.dyndns.info/gallery3/index.php/my-own-windowfarm/airlift2 for airlifting and for a step by step lesson: http://windowfarm.tk/?cat=3
Thanks for all in suggestions, will go get the kits and build the air-lift this weekend
