Are Pellets compulsory?

I would imagine a gravel vac would be much cheaper and more efficient at cleaning gravel than the filter. It helps with your weekly water changes too.
 
yeah, its usually a plastic tube about 2 inches in diameter hooked up to a hose. If you have dirty gravel, push the tube into the gravel, let it suck out the brown stuff, pull the tube out of the gravel before sucking up the actual gravel, then move to the next spot.

After doing this consistently for awhile with weekly water changes/gravel vacs, your gravel should start to clear up.
 
If you have sand, the suction on the vacuum will probably be too much and you can't push it down too deep or else you'll be sucking sand.

I have fine gravel in my 120g. I push the gravel vac down into the rocks, the rocks start to move slowly up the tube, usually the top few spin and twirl in the suction. When the rocks reach about half way up the tube, I slowly pull the tube out of the gravel, the rocks in the tube fall back down into the tank. Usually during this whole process, dirt is being sucked out of the rocks. There's a cloud that appears in the gravel vac tube. If your tank is dirty, the darker the cloud.
 
All under gravel filters do is trap the crap in your gravel. If you know your tank is overcrowded, maybe you should solve that issue. If you dont push the tube in the gravel, how will you get the dirt out? or you can stick your hand in there, throw up the gravel have all the crap float around your tank and then do a water change.
 
no...its because its so convenient... you can just make a sump or an HOB and use the same media, or have a canister with crappy media or no media at all. TBH, not to be too blunt, but aros really shouldnt be your first fish...your 2 months of research are REALLY lacking and now is not the time to be doing more of it...
