spot algea I have a 26 gallon 4 foot tank with 40 wattts of light over it. I used to have brown algea about 4 weeks ago that covered all the plants and then I bought a bristlenose pleco and he cleaned it all up. I had bright green plants for about 2 weeks and now on the brazilian sword and the glass I'm getting blue/green colored spots all over and it is even hard to rub off with a spnge from the glass. How do I get rid of that. |
