i also don know what type.. just small 1 cause just for 2 goldfish... ya the water should use clean water rite? i don dare use paip water..
I use overnight paip water, add some nutrafin water conditioner that all. As long as you get a clear and clean water from the filter it is a good filter. Don't change the whole tank of water unless you got a problem with water quality.
