75 gallons

  1. Beginner Freshwater Aquarium
    I have: -a 75 gal tank -2 koi's -2 heating sticks 150 w each. -1 eheim 2215 filter 2 airstones. Is this a good or bad set up, regardless of the tank size. Anyways the aquarium has been around for a while now( almost a year), and for the past few weeks i've been getting really cloudy water...
