also starting to grow some on the glass

 

First thing I though of also. Normal for a new tank. Once the silicates in the water are used up, they will die off. The brown stuff you see are just the dead diatom skeletons. A good clean up crew will take care of that once your tank cycles. Now, during your cycling phase, remember not to skim and use only the actinic portion of your lighting.

 

sorry about that with the pics,

also are you saying my tank was not done or is not done cycling? cus i even had a dog face puffer in there live and well for about 2 weeks untill i took him back as i want to start getting some corals once my tank is up and ready and he had to go...

i do not have any tests or anything as my lfs dose all that for me each time i visit.....but they said everything was good to go with my water and was ready for fish....kinda confused now...
