Help! My Fish Tank is out of control w/ green algae. [View all]
I've had a freshwater fish tank for over 20 years. A couple of years ago we did some remodeling which required moving the 20 gallon fish tank so I thought it would be easier to get a new tank for transferring the water & fish. I also wanted to replace the blue gravel to natural stone (which I rinsed & de-chlorinated thoroughly). Ever since I've struggled to control the algae on the sides of the tank.
My original 20 gallon tank had the old fluorescent tube lid, a bio wheel filter & a heater (don't know what kind). At some point we had to replace the flour scent bulb w/ a single strip LED light top.
The new replacement 20 gallon tank is the Top Fin starter aquarium from Pet Smart. I have the lights on a timer (there are 3 LED strips). I can't tell if the thermometer is adjustable. I don't know what is causing the excessive algae build up - if it's the filter, thermometer, gravel,....
I tried adding an air stone strip but that seemed to make matters worse.
I have a few plastic plants & a rock decoration. I only buy cheap Tetra's and they don't seem bothered at all by the algae. In fact, it's almost impossible to kill them. LOL
Thoughts or suggestions?
