How To Perfectly Set Up My Sponge Filter?

In essence, the way you set your sponge filter matters a lot. Besides, you can locate your sponge filter under the substrate of inside aquarium walls. Similarly, setting up sponge filters becomes challenging for many, and you might destroy the entire setup with one mistake. Luckily, I have provided the below-detailed steps on how to perfectly set your sponge filter:

(1) First, ensure you got all the necessary components. And this comprises the check valve, air pump, airline best lift tube, sponge filter itself, or air stone. You should have every part because if anything misses can cause the entire structure to fail.

(2) Take your sponge filter apart; remove the plastic strainer located inside the foam. Besides, spreading everything on a clean floor /table will help you know anything missing.

(3) Now detach the specific bullseye right from the top of the strainer, followed by replacing it with a quality airstone right at the bottom of the filter. Further, connect your air stone at the center of the bullseye via airline tubing in short length. Besides, in some cases, the sponge filter might be too small for the tubing to perfectly suit in, so you should connect your airstone directly to the bullseye.

(4) Next, attach your bullseye to the strainer, followed by returning it to the bottom. And to ensure this foam will firmly stay on the bottom, consider connecting the specific strainer to the weighted base, which is usually delivered with a sponge filter. The sponge filters operate well right from the bottom, where more contaminants settle.

(5) Take the lift tube starting from a specific end of airline tubing; attach it to the center of the bullseye top. Attach it firmly inside out in order for everything not to loosen off after filtration begins.

(6) Now, immerse your assembled sponge filters in the aquarium, squeeze out the air bubbles which might get trapped inside the foam. And this aids the filter foam to eventually sink into the bottom because everything might fail if some air gets trapped within it.

(7) In this step, turn your attention right on the air pump. However, consider making detailed cuts on airline tuning that will enough to typically reach your sponge filter into the water. And after attaining the correct length, now connect the specific air pump to the sponge filter.

(8) Where you will position your pump is much essential. When located below the top of your tank, this means the water will effectively flow back to airline tubing when this pump is off. And to stop this, install the check valve to avert this backflow. Ensure the check valve end is typically indicated via colored horizontal line and facing air pump direction.

(9) Finish your set with the addition of the drip loop suitable power cable running your air pump. Essentially, this wills top moisture not to come into contact with your power cable because this can be disastrous. Now tune on your air pump, and see if bubbles will emanate from the sponge filter immediately, and this a sign that your whole setup is perfect and successful.

Why Are The Bubbles Coming Out On The Sponge Side?

There few reasons why this could happen:

(1) First, maybe you removed or shortened the lift tube. Generally, a shorter lift tube will not have enough suction to pull bubbles up on the center column; some bubbles will escape.

(2) When air pressure from the air pump is too intense, excess air will be forced into the sponge filter this causing extra bubbles to leak out on the sides.

(3) If the air stone is also crooked inside your sponge filter, you should shorten tubing, attaching air stone right to bullseye to eventually to hand is straighter.
