Hey guys,

As the topic title says, I recently moved my tank ( about 2 weeks ago) to a new house. When I did the move, I left the old sand in the bottom of the tank while I did the move and reused this sand. Of course the sand got stirred up and the tank was 6 months from it's initial startup so it had some good life in it. There is also quite a bit of flow in the tank and in the area where there is this algae.

I was using supposed RO water from a machine at Shell, however I wasn't testing it. So this could have contributed to it, however I never had any problems before.

Since then There is one spot that seems to be growing rust looking stuff every day with a rust color on the sand, however in the morning after the lights have been out for some time it is gone, but developes again throughout the day.

I did purchase an RO unit and set it up and have done one water change with it so far, doing another on Friday.

Could this just possibly be a liberation of nutrients from the sand being stirred up and creating some nusence algae? Should I just wait it out to see what happens? I will get a full tank param tonight and post what it is at. Everything is still thriving and I have been feeding the same as usual. Oh and I also added a skimmer last week to the system.
