Hey guys thinking of buying a new filter for my 15 gallon tank. I have a filter in now which has a airflow which blows bubbles to oxygenate the aquarium. Like that about the filter so would like it to have that. Or is there a small external filter on the market...

Stick a corner Hamburg Matten Filter (HMF) in front of your current filter. It will dramatically increase your bio filtration as well as hide the current pump.

Have I got to build it myself dont see how it would work with my other filter. Was looking on upgrading the 1 i have. Do u use a power head with that 1.
Yes you have to add it to your tank, and then poke a hole or using tubing to extend the output of your current filter. Ignore the PVC tube that comes with it. You can use an air pump with that one or a powerhead.

......pair this with an under gravel sponge filter and u should be ok......
turn the filter to low and take out the sponge filter if u happen to be blessed with fry!!!!!!
be careful with the air pump......do not deathrow records urself!
