Tank going manky!?

[JadeandScott]

We have been doing plenty of water changes as we had sick fish but think they're on the mend now... But over the last few days we've noticed a cloudy/spider web fluff at the bottom of the tank n they're is brown patches on our rocks...(assuming that's left over food/ waste) the water is perfectly clear!
We are waiting for a gravel vacuum to be delivered.. Is there anything we could do? And what is it?

Do you have driftwood in the tank? New wood often developes this white fuzzy stuff....it's safe for the fish and it'll go away on its own after a while. If it bothers you just wipe it off. If there isn't wood in there it's likely uneaten food that's gone moldy and should be removed when you get your vacuum (and if it is food then you're probably feeding too much ). The brown patches could be diatoms.....common in new tanks and nothing to worry about; it should go away after a while. In the meantime you can wipe it off.

If you can post some pics that might help us ID it better.

We cleaned it out last night and I managed to get rid of most of it! I cleaned the brown spots off the rocks too.
No there is no wood in the tank x
