Ok i know you told me not to use an undergravel filterbut i had it before you told me that and theres alot of poop and old fish food gathering ontop of the gravel and i was curious why this is happening?

I still plan to use the ungergravel filter, but can anyone tell me wats the best filter that takes the stuff from the gravels surface

u see ive done that, many times, but it comes back too quickly, the fish even start to lose the activeness and lie around, thats common for oscars but they get really droopy

you could be over feeding, or could be to many fish, for that size tank, maybe!! a type of power filter, might help. whisper make good ones.

theres only three fish in the tank, i siphoned the crud out, and then i realised there was a unearth section of filter so i covered it and its working, im still buying a above gravel filter to be safe

You could also try using various types of catfish as bottom feeders. Depending on the size of the tank and the fish currently in the tank a group of cory cats may or may not work. This method has always worked for me.

in a previous community tank i had cory cats and they worked great, but this is an oscar tank, so i might get a larger pleco, possibly a sailfin

I had a pleco with my oscars and they all got along great. Although I started with the pleco larger than the oscars were.

How do you siphon? You should press the siphon down in the gravel about 1 inch / 2 -3 cm for better result. This helps you remove more "crud"

when i have the gravel cleaner i use that siphoning method william, but this time there was just "crud" ontop of the gravel so i just siphoned that off, the next day i did a full tank clean
