i bought an xp4 to replace my fluval 205 and 304 so i would just have 1 filter to maintain, the xp4 is new so what would be the best way to introduce the new filter to get it mature enough to take over from my fluvals ?
is there anything i can add to the water to encourage the BB to grow quicker ?
thanks
