User questions & answers

Question:	How many do you put in a tank
Answer:	That depends on how big it is and your aeration set up I use the to increase the suction power of my two large sponge filters in a 55 gallon tank.
Question:	will this work for 1.5W airpump? It's what I have already
Answer:	As long as your pump puts out air it should work.
Question:	Does it need a air pump or anything? My boi Flynn the Beta would love this in his 3 gallon tank
Answer:	Yes it requires an air pump and an inline regulator or it may be to strong for your beta
Question:	How many do you put in a tank
Answer:	Only one; my best has a 1.5 gallon tank, which practically only holds one gallon. It's probably "too small" for him, but it's been his home for a year, plastic plants make his lounge chair and tunnel, and he loves his bubbles. He'll swim over, ride up the bubble stream, swim out and repeat over and over again. When I turn off the bubbles to keep his food from being scattered underwater, he will stare at the stone until I plug it back in. A happy Siamese Fighting Fish with an attitude. He knows.

User questions & answers

Question:	Will these float to the top
Answer:	no
Question:	Does this come with everything I need
Answer:	yes
Question:	what capacity air pump do you need to have full bar work rather than just by the end where tube is connected
Answer:	You can use any brand of air pump. I have 3 running and each one is connected to a different brand of air pump. It helps to have a flow control on your tubing to control the amount of air you want. The one thing to remember is to soak the bars for 30 minutes before using them. Each bar is unique with the style of bubbles that come out. Your fish will love it once they get use to it.
Question:	how can I mount this to the aquarium glass wall
Answer:	I used aquarium silicon. I adhered it to the wall before testing (my error). I have a 6.5 watt air pump and I get no bubbles. Zero! Waste of money for me.
