Habitat - Indoor :: How to work this airpump

[Simba]

I bought a new tank (used) and it came with an air pump. I have some pieces here and I'm just confused as to how it works and what to do with it.

I'm not sure if the blue thing belons to it, but it came inside the tank and I couldn't find anything else it belonged to.

The end of the hose has this weird hard thing in the end so I cannot figure out how it connects to anything or works.

Any help is appreciated. Thanks bunches

Nevermind, I just broke the thing on the end I thought it might come off but it just crubled in my hand

sweet. The little blue cylinders(2) are one way check valves so that only air can pass through and water cannot come back through which would ruin the air pump. When the pump is turned off, it could create a siphon affect, siphoning the water back into the pump. Thats why the valves need to be there.

The grey piece on the end you broke was just a cheap airstone, so no biggie. They can be had for a dollar or two at any petstore.

The blue one however, is a bubble curtain. Put the airline tubing onto the end with the nozzle like piece. Then put it in the water, bury it under your sand or river rock, or just let it sit on the bottom of your tank, plug in the pump and watch the bubble curtain come up.

Just put the pump in your tank stand, and if it is too noisy, you can put it on top of a cloth or rag to quiet it down.

Hope it helps.

you can bury them in the sand and still get bubbles? how big of a pump would i need for a 4' bubble curtain? thanks,

Thank you. I nearly cried when I broke that part because I Thought I ruined my deal of a purchase.

I figured out the other part and she seems to love the "bubble curtain" if biting at it is loving it but she seems happy It is obnixiously loud so only occasionally, but still...

Thank you so much!
