Jess Posted February 24, 2021 Share Posted February 24, 2021 (edited) I'm trying to run air to both my tank and my BBS hatchery. I thought this was a pretty simply endeavor: plug in Aquarium Co-op's AMAZING nano pump, then plug in two different outputs at the ends of the t splitter. But air only comes out one side (down to the BBS hatchery). I have checked that the valve is totally opened up....I clamped it all the way down and then opened it all the way up. So it's not that. Any clues? Is it because one is lower than the USB nano pump and the other is higher, so it doesn't send air up? Pictures below...I'm sorry they are pretty bad. 1. USB Nano connected to airline T splitter 2. One end of splitter goes into the tank: 3. Other end goes down to my BBS hatchery Edited February 24, 2021 by Jess clarification Link to comment Share on other sites More sharing options...
Lemon Posted February 24, 2021 Share Posted February 24, 2021 which ever way has less pressure will get the air. so if you get a valve you can adjust which side is getting more air 2 Link to comment Share on other sites More sharing options...

You may need to put a valve down to the hatchery. Their general locations are I think less important than the overall resistance. The pressure in the little hatchery is likely much less than at the bottom of your tank. I would think the pump should be powerful enough you just need to direct that power a bit better. 1 Link to comment Share on other sites More sharing options...
lefty o Posted February 25, 2021 Share Posted February 25, 2021 more than likely, because of the minimum size of the nano air pump, it does not have enough air flow to over come the resistance to flow from 2 tanks, and the hatchery. the hatchery having less of a pressure head/resistance, it gets the air flow. 1 Link to comment Share on other sites More sharing options...
Brandy Posted February 25, 2021 Share Posted February 25, 2021 (edited) I have a 4way gang valve with a single nano pump running my hatchery. It isn't the pump, it is the setup. You need valves. Edit to add: I can run 3 brine hatcheries with room for a 4th, or 2 large sponge filters off one pump. You should have enough power.

ElTigre Posted February 25, 2021 Share Posted February 25, 2021 Like @Brandy said you just need a valve. Id start by adding one to the line headed to the hatchery and close it until you get enough flow in the tank and hatchery. This way you can also close than line completely when you aren't hatching brine. 2 Link to comment Share on other sites More sharing options...

Daedalus Posted February 25, 2021 Share Posted February 25, 2021 The nano pump can not be split. It is only for one output. You'll need a bigger pump or a second nano pump. Link to comment Share on other sites More sharing options...

CT_ Posted February 25, 2021 Share Posted February 25, 2021 I'd also add a couple check valves if you haven't already. last thing you want to do is accidentally siphon your whole tank into the brine hatchery 3 Link to comment Share on other sites More sharing options...

Jess Posted February 25, 2021 Author Share Posted February 25, 2021 Thanks, everyone! I had an extra Ziss valve lying around (came with the Ziss hatchery, ironically I wasn't using it LOL), so I hooked that up and now it works perfectly. So, definitely the USB Nano pump can provide enough air at least to two lines, but you need a valve on each line. Also added the check valve down to the hatchery. Thanks for that reminder! 3 Link to comment Share on other sites More sharing options...
