DIY Simple PVC Sponge Filter for Aquariums!

Hi Everybody,

I Recently made a glass tank but the problem is that i don't want to spend too much money on those commercial aquarium filters .

So, I made my own PVC Pipe Sponge Filter!

With a Cost of Only Rs.60 = 1$

For only 1$ , I Had an Handy + A Little Big Aquarium Filter which saved my money.

And best of all PVC is Non-Toxic to Fish. Vote this Instructable for PVC Contest ^

* I Would not Recommend This for Fishes Like Discus , Oscar, Jewel , and Cichlid or any other fish which require Big Filtration Systems.*

* These are used as a replacement by many hobbyists to protect fish *fry* from getting sucked into those high power filters*

So Friends , Let me show you how i made it.

So First of all,let me Explain what a Sponge Filter is and what are it's Benefits:

Sponge Filter is a biological filter which needs an Air Pump to suck water from bottom of the filter and then passing the water through the sponge and exit through top. By this Simple Process Good Bacteria Grow in the Sponge and Helps to Convert the Fish Waste which passes through the sponge. We can simply say that we are making a Restaurant for Bacteria to EAT and EAT.. LOL

Sponge Filter Also Helps to Catch the Debris and clean the water in Aquarium.

*Do Not Use this Filter if your Tank has ICK Disease*

Because ICK Parasite Gets a Place to Live in the Sponge in this Filter and then it would take many days to treat this disease.(If you have fish in that )

Here's the list of Things we Need:

1) PVC Pipe (3cm Dia.)( Length should be 1 inch shorter than your water level )

2) PVC End Caps ( Not Rubber Ones)

3) Multi-Purpose Sponge

4) Hot Glue

5) Air Tube to Air tube Attachment.

6) Aquarium Air Pump

7) Drill

So First we would need to make some deep cuts and holes to PVC Pipe so that water could come in and Go Out from all Sides

I Used my Diamond Cutting Attachment to make some deep Cuts.

If you donot have this attachment then try to drill bigger holes .

I Used a Multi Purpose Plastic Sponge from bottom.

*I Recommend Plastic Sponge Only! Because Other Sponge have minute Fibers which could float in Aquarium.*

Now Drill 1 Hole at 1 End Cap

a 5mm hole would be good to fit the Air Tube Attachment.

Now pass that Airtube attachment half in and pour hot glue inside the end cap.

Make sure Attachment's Nozzel is not blocked by hot glue.

So We have to Create pressure in bottom so we would add an airtube till bottom.

Now Close the Pipe with end caps.

if you feel that end caps are not tight. then you might try fixing it with hot glue.

Now Supply Air At Nozzle wit Air Pump and Your Filter Starts Working!

Finished!
