The aquaball is fine in the 60 litre, though I've had to turn the flow down on the aquaball, but then that model was designed for 100 to 200 litre tanks. For the 125 litre, I much prefer the biopower. Then the filter in my 60 litre started to play up (it was very old) so I got a biopwer 240 for the 125 litre and put the aquaball into the 60 litre. I used to have an aquaball 2212 with an additional basket in my 125 litre. The power-diffuser is adjusted to regulate. The pump output and throughflow can be set by the control knob on the outflow nozzle. Thus the outflow of the filtered water can be aimed in any direction. The ball-shaped pumphead sits in a ball joint and can be turned all round. I may sound like an Eheim salesperson, but I do have both filters. Find helpful customer reviews and review ratings for Eheim Aquaball Powerhead Only 1212 170gph swivel NEW at . The EHEIM Aquaball Powerhead is a powerful ball- shaped universal pump. It has one basket with a sponge and one basket of substrat pro, The aquaball with the same flowrate as the biopower 160 is the aquaball 130 (2401), though the quoted tank size for that is 60 to 130 litres. The smallest biopower, the 160 (2411) is labelled as being for 80 to 160 litre tanks, but you can turn down the flow rate (and on the aquaball too). The water is drawn into this basket, through the sponge then up through several baskets of substrat pro, through the fine sponge and out.īecause of the amount of substrat pro the biopowers hold, Eheim are marketing them as an internal filter with external filter technology. Right at the top where the aquaballs have the small box, the biopowers have a small fine sponge. The other baskets are filled full of substrat pro (no centre core like the aquaballs). With the biopower filters, only the bottom basket has a sponge, the same type as the aquaballs. There are 3 models for aquariums from 80 up to 240 litres. The water sucked in at the bottom is pumped to the top through the various filter layers and after filtration directed back into the tank. Water is drawn into every basket, through the sponges to a central core, then up through the top box and back out. The inlet basket with filter cartridge for the mechanical-biological prefiltration is located at the bottom.
