Can someone tell me if this is brown algae? (See pic). It's developed since upgrading my lighting to one of these off ebay.

It's on everything!!
I've introduced some Zebra Nerite snails after taking advice from elsewhere. I've put 4 in a 110 ltr tank. Are they as good as people say at controlling algae? And how long does it take them to get it under control? If indeed they can.
