The only thing I can thnik of is algae.

Sounds like hair algae.
Nothing horrible, though the plants will get less light and potentially less CO2 and nutrients.

 

sounds like algae - how much light does that tank get in a day? would you be able to reduce that any if you needed to?

 

get some bristle nose plecos and it'll soon be gone....personally I like the look of it growing off the wood.

 

so its not too bad then, the tank gets 8-10 hours a day with the light on thanks gfor the advise guys
