hi, i am setting up a new 2ft tropical tank, but i have the choice of an under gravel filter.. (with gravel) or sand with fluval plus2 cartridge filter.
i already have 2 other tanks with sand and cartridge filters, and the sand stays very clean,
if i use gravel, will it require maintenance to keep it clean? and what is the best type of filter for gravel- cartridge or under gravel filter?
please help!!
thanx, giles
