I was wondering if this could be done. I guess you'd just have to add an air pump that was badass to make enough bubbles. I think I'd be worried that either the flow was too slow moving through the sump or that it would be too fast going through the skimmer.

oh your thinking 100% pump free skimmer. Mine is gravity fed by my drain line but the skimmer body does have a recirc pump on it with a needle wheel impeller.

Oh okay...yeah I thought Sanh meant completely gravity fed minus the air bubbles.

I did it before on my 366 dt. It did have a recirculating pump but the Bk 300 external only needs 300 gph so I knew it was draing more than that so it was cool. Worked out great and save electricity.

Don't have a tank right now or should say that is running lol. But when it's wet it will just have a bk double cone with a speedy pump in the sump. Not as exciting but it gets me all giggly lol.

A no pump, all gravity skimmer uses the drain to fill it, and then an air stone to make bubbles. Thats if ur trying to be all hardcore green and save electricity. I'm sure it's pretty crappy though

No no no. Most of u r to new in this hobby to have ever seen one of these in action. It's a special type of skimmer called a downdraft skimmer.

The one i seen modified to run off the drain (pump less) was modified. He cut the downdraft peace and added 5"s to it. Then had a 1" inlet not the 3/4" inlet that was stock. It worked really well but not as good as the cone skimmers that r on the market now. If I could have found a downdraft skimmer I would be running one right now along the side the ATS.

Aww ok. I almost bought a used downdraft skimmer off of someone before and didn't even know. It had bio balls in it as well. Forgot the name brand though.

you dont have to use an air stone you can make it circulate with a pump which makes it pretty dang awesome

Me for a long time I connected it to 1.5" drain and I feel like its not enough so I run a biopellets reactor in a wye so it putting 800- 1000 gph to the skimmer
All have gate valve so I can control the flow
I used to have gravity feed chiller, reactor and almost every thing I can run with it. My restart have 2 extra drain for future gravity feed reactors

It can't because you need pressure to make uniform bubbles .
