I just did a 20 gallon water change yesterday and today i noticed the water looks cloudy. Is there anything i can do? I also feed my eel tuna chunks yesterday is this what maybe made my water cloudy.
tuna is fatty fish so you may have a piece not eatin or it may just be a reaction to the mess your eel made eating it if you run carbon add some fresh and rinse your sponges and water changes always do your tank good
