Is Rust colored spots on rocks and plant leafs an algae?

[betowess]

Here are the conditions. I am about 2/3 through the nitrogen cycle. Nitrites are somewhere between over 2ppm to 4ppm. I'm waiting for the nitrates to start clearing it up. This is a moderate/ heavily planted 26 gallon with 6.5 to 6.8 [acronym:51a0b33ae0="Measure of the concentration of hydrogen ions"]ph[/acronym:51a0b33ae0]. [acronym:51a0b33ae0="Power compact fluorescent"]PC[/acronym:51a0b33ae0] is a 65watt with 50% 10000k and 50% Actinic (spelling?) [acronym:51a0b33ae0="Carbonate Hardness"]KH[/acronym:51a0b33ae0] is around 3 to 4 degrees. I am going to try to find a source of less acidic H2O as my well water is in the high fives of [acronym:51a0b33ae0="Measure of the concentration of hydrogen ions"]ph[/acronym:51a0b33ae0] right now with this drought here in the West. I just introduced [acronym:51a0b33ae0="Carbon dioxide"]CO2[/acronym:51a0b33ae0] but am adding [acronym:51a0b33ae0="Oxygen"]O2[/acronym:51a0b33ae0] at night too keep the [acronym:51a0b33ae0="Powerhead"]PH[/acronym:51a0b33ae0] from plummeting. I also have put in an oyster shell to add a little [acronym:51a0b33ae0="Crushed Coral (if substrate) or Corvuscorax (if referring to person) or Counter Current (if referring to a Protien skimmer) or cubic centimeter (if referring to a measure of volume)."]CC[/acronym:51a0b33ae0] to help with the [acronym:51a0b33ae0="Powerhead"]PH[/acronym:51a0b33ae0] and [acronym:51a0b33ae0="Carbonate Hardness"]KH[/acronym:51a0b33ae0], though haven't noticed any improvement yet. I also moved all the fish except some tough Danios back to my other tank until the cycle is done.

Lots of new plant growth, but old leaves are dying probably from shock in a new tank. Have flourite and have supplemented a little Seachem excell and potasium. Haven't done a h20 change yet because I want to get this cycle over [acronym:51a0b33ae0="As soon as possible"]ASAP[/acronym:51a0b33ae0]. What is this rust colored algae? Its on the rocks too and the water is kinda cloudy with that tint abit. Should I think of a partial H20 change now, or tough it out. HELP! Betowess
