How to Create an Undergravel Filter for Your Fishtank (versi bule)
Steps
-
1
Know the size of your tank. Measure its length width and height.

-
2
Plan. Try to think of a
design that would allow the PVC to make a closed circuit, and cover a
good amount of area. Also leave about a half inch from the sides of the
tank and the PVC tubing, as this will allow your substrate to fill in
the gap hiding the UGF. Making a closed circuit simply cuts a few
dollars off the price of the build by not having to buy caps. Double
check to be sure.

3
Go out to your local hardware store and pick up lengths of 1/2" or 3/4" PVC.
My local store sold it in 10' lengths, and it cost > $2.00. 1/2"
would be best for 5 1/2 - 20 gallon tanks. 3/4" would be better for 30
or more gallon tanks. Make sure you have all of the elbows and T
connectors you'll need. Take into account the lift tubes, which will
need 1 T connector for each lift tube
-
4
While at the hardware store, ask the clerk where you can get PVC cutters, I got a decent pair for $6.87. Try to get the kind that ratchet, it will make cutting easier.
-
5
Once you've got the filter pattern planned out, begin cutting and assembling the pieces outside of the empty tank.
-
6
After all pieces are assembled, use a hammer and nail, or a power drill to punch holes into the bottom of the PVC pipes.
This will allow water to be drawn into the UGF as it operates. Be
careful not to hurt yourself, or go through the other side of the PVC
pipe.
-
7
Now take the completed UGF and put it into the fish tank. Make sure the uplift tubes are not sticking out of the tank.
-
8
Run the air tube(s) down to the bottom of the uplift tube(s). For PVC pipe 1" or greater in diameter attach an air stone at the end of the air tube and drop that into the uplift tube.
-
9
Using proper techniques,
finish setting up the aquarium (washed gravel, de-chlorinated water,
additional power filter (if desired).
