Brown Algae, I Think? Please Help

[thabigo]

So I have a 36 Gallon Cichlid Tank
Tank: Aqueon 36 Bow Front Tank
Filter: Aqua Clear 70
Water Temp: 76 Degrees F
Lighting: 17 Watt T8 Full Spectrum Bulb (Came with Tank Kit)
Current Stock:
1 Red Zebra
1 Electric Yellow 
1 Duboisi 
1 http/www.fishlore.com/profile-demasonicichlid.htm (Which isn't eating much but that's another issue)
3 Tiger Barbs
1 Bristle Nose Pleco
1 Rubber Nose Pleco

Tank was established on 06/09/2014 
With the 3 Barbs.

I started to notice this brown stuff on the Fake plants I have but only in the center of the Aquarium about a month and a half ago.

I Put two TF South Seas Marine Rock inside my tank and about a week and half later I noticed some Brown stuff on the rocks. There is also some on my Lace Rock. From what I have been reading it says it is Brown Algae but I wanted to confirm and see how to get rid of it because it looks bad.

Any Help I would greatly Appreciate it, Thanks

You can probably scrub it off the fake plants. 
How often do you do water changes? Any direct sunlight? Also make sure you don't overfeed, even the plecs can't clean up everything. 

 

[thabigo]

Water change every 1.5 weeks or every other week, no Direct Sunglight, and I don't over feed.

It can still happen. It happens in my bettas tank. Just try rubbing it off with a rag.

Here you can find some information that may useful.          
Brown algae (Phaeophyta). The brown algae, or Phaeophyta, are shiny brown seaweeds that are especially abundant along rocky coasts, although some float in the open ocean. Brown algae are large in size and include the giant kelps, which are located along the Pacific coast and form forests that provide habitat to a wide range of marine life. Some species of brown algae have structures called holdfasts that anchor the algae to submerged rocks. Attached to the holdfasts are stemlike stalks that support wide leaflike blades. These blades provide the major surface for nutrient exchange and photosynthesis and are lifted up toward the water's surface by air bladders. Brown algae contain an accessory brown-colored pigment that gives the plants their characteristic dark color. Other well-known brown algae are the common rockweed Fucus and Sargassum, which floats in a thick, tangled mass through the Sargasso Sea—a huge area of slow currents in the mid-Atlantic Ocean that supports a variety of marine organisms.
Yellow-green algae (Xanthophyta). The yellow-green algae, or Xanthophyta, primarily occur in freshwater. They can be either single celled or form colonies, their cell walls are made of cellulose and pectin compounds that sometime contain silica, they can have two or more flagella for locomotion, and they store their energy as carbohydrates. They derive their yellow-green color from the pigments carotenoids and xanthrophyll.
