Air pump/water pump?

    Hi everyone! Recently bought a new fish tank which is 93litres (20.45 gallons) and I'm keeping tropical fish. I have a silver molly and black molly in there at the moment. My tank came with 100g activated carbon+anti-nitrate resin in a net bag, 500g bio ceramic rings in a net bag, white filter foam and blue filter foam which all makes up the filter system. I have installed this into the side box in my tank along with a heater. My tank came with a water pump which was pumping water into my tank but I didn't understand how to work the pump properly and my mollies seemed to be gasping at the surface (I think), I then got rid of this water pump and switched to an air pump with an air stone and my mollies seem to not gasp at the surface much at all. My issue is the air pump is loud! I've tried tetra and other brands but I hate the noise. Do you think I should switch back to the water pump because it was less noisy or do I not need a pump at all?

    Sorry, I'm new to this and just want to make sure I'm doing everything right! Thank you all.

    does your water pump create water agitation? or break the water surface at all? is it a built in filter? to make it less noisy put a towel or sponge or anything that can absorb the noise....

    Hi, the pump did create agitation yes. And I could see the vibrations on the surface but it just seemed like my fish were having issues with oxygen. My filter is built into a box on the side of the tank. I've tried a sponge and a towel but the buzzing is just uncomfortable after a while lol

    i know how you feel,i have a tank with air pump but its near my garage so i dont bothered by it.One thing you should know is air pump doesnt provide oxygen to the water.It just help to breakdown the water surface so oxygen can easily diffuse into water and reduce CO2 in water.If possible,could u please show me picture? maybe i can find a way to get rid of your problem

    i see...i suggest u try to use water pump and see how your molly doing...livebearers sometimes spend most of their time at surface
