Hi all I've got a 230l tank and want an internal filtet as I don't like all the pipe work external come with so could someone suggest a good internal I could use
Or rather than the aquaball, look at the eheim biopwer filters. They look the same as the aquaball from the outside, but have baskets of substrat pro rather than lots of sponges. The biggest one (the 240) is supposed to be for 240 litres but like star4 says, I'd go with more than one in your tank. I'm running the 240 in a 125 litre tank.
And it's very quiet.
