I have had a planted 150 gallon tank set up for 3 months now.3.5 watts per gallon pc lighting and they are on for 11 hrs.They have started developing a brown hair like algae. How do I get rid of it ? ;D ;D

Welcome to simplydiscus!

Hmmm! Check out this link:

HTH! Not exactly sure about the brown hair like algae! Maybe there is a pic on the link I posted. ;)

I have the same problem, and like the article says, I have to cut the plants way back, and hope they make it. My smaller leaf plants like Horn wart will not get it, but most of my very broad leafs will get it.

Good luck, and let me know what you do!

Is some of the algae pretty long (inch or so) and actually look like hair. Could be thread algae. Had something like that in my tank. Thought it was cat hair.

I have a low light tank, so different situation than yours, but you could try to post what fertilizing you are doing so someone on this board good with that could see if all looks in order. In tank, when I cut back from 12 hours of light/day to 10, the thread algae decreased.

Also, if it looks like one of the other pictures in the link Ronrca posted (e.g. the middle picture of red algae), SAE's might help get rid of it. I don't think they help much with thread algae.

Sounds like red algae. This is a tricky one. It usually comes with high temperature and too low lighting. Algae eaters probably do not eat them and algae fighting chemicals usually do not work. I will try to remember how I got rid of them. :-\
