Fish Fanatic
I have been getting red algae on my gravel for a few months now and at first I thought it was brown algae but thought maybe the lights or the decor of the tank is making it look a little redish but it started growing on the outflow of my filter and is actually becoming stringy and is definitely red. I tried to look up red algae but the only stuff I can find has to do with salt water tanks which mine isn't. I took a pic of it, the white stuff is just air bubbles caught in the water flow but you can see the red all over the plastic of the filter and the stringy stuff.
Any ideas on what it is and what is causing it? I know our water company had a problem around when I started noticing it and we weren't supposed to drink or cook with the water without boiling it first but that has since been fixed and I'm still getting this even after I have cleaned it. I also have problems with brown and green spot algae but have had those problems for years.
