Help Identifying problem algae or bacteria

[smelton16]

I cannot figure out how to get rid of this stuff. Looks like long stringy red algae that will come off with a turkey baster. Problem is, it comes right back. I have treated tank with Chemi Clean and even tried Red Cyano RX. I do not think its Red Cyano but does look like some on the sand bed. I had this about 6 months ago, and chemi clean took care of it. I do not like putting chemicals in tank but will do anything to get rid of this stuff. After looking at parameters below, wondering if 0 nitrates and phosphates are causing any issues. Any suggestions to get rid of it? I know it takes time and patience, but this has been around for a while now. Tank is a year old. Do 30% water change weekly.

Tank is 15 Gallon Cube

2 clowns
2 hermits
Emerald Crab
Peppermint Shrimp
Few Corals which are covered in string algae as well


PH: 8.0
KH: 12
Nitrates: almost 0
Phosphates: almost 0
Ammonia: 0
Nitrite: 0

Stop doing water changes every week. Once a month may still be too often with such a small bio load. When the nutrients come up the diatoms will go away.

okay. thanks! What about the red string algae?

No such thing as red string algae. As the tank grows up something else will take the place until the tank grows up and hits cruising speed.
