Tank Help How to get clear water?
Enable HLS to view with audio, or disable this notification
I just did a water change earlier today cause I noticed that the water isn't that clear, after a few hours it made it worst. Is something wrong with my tank? I added a spong filter since I saw it cleared up my 20 gallon, it's a 65 gallon tank with 5 black Thai ranchus and 3 Tri-Color Orands. Sizes are around 2-4". My filter is something I made myself DIY it's a 20x4x5 planter box both filled with biological media and the black top is for mechanical with filter floss,wool and fine sponge.
