Predfan27 said:It is most definitely diatoms. They appear with newer aquariums. Although that last picture looks like your leaf may be dying.
I would be interested to know your lighting schedule also.

Bobbybillymike said:You have driftwood in your tank correct? The brown film is coming from your wood. The spike in temp caused the tannins and dust of the wood to spread throughout the tank quicker, like putting a tea bag in hot water. It then collects on the usually hard to see algae film that form in all tanks. All you need to do is a 25% water change and scrub of the films on the hard surfaces then add new carbon to your filter.

Borderlesscott said:It's just Diatoms - new set ups always get them, they not do any harm apart from annoy you. Easy to clean, though will probably be back shortly afterwards - they will go in there own after there food source is finished, usually happens close to the end of your tank cycle. IMO its nothing to do with your bogwood, you would have noticed the tannins in your water first if there was a huge release from the wood, boiling bogwood is advised though if you don't want tannins in the future.
