Aquarium Advice Newbie
hi all... please help... i love fish tanks had a big tropical tank when i was younger... now i bought a bigger tank from an old lady with back problems. This tank now is a coldwater tank with BIG goldfish and koi fish that came with the tank, i have added more fish,aswel as more plants(fake) and bubbles and rocks,a new filter aswel as the old one wasnt sufficient. It looks very nice now and i do a weekly water change with anti-chlorine. The water turns milky at about the 4rth day, and Yesterday i read on the net about "cycle" Now What do i do? how do i Cycle the tank without loosing the fish?
