Are they coralline algae or nasty diatoms?

Hi,

My fish tank is now about two months. Now everything is fine and It has been great.  Now I see different types of green Algae from what I had before.  Could someone let me know what are they?

Thank you!  They are different from the green algae that I had before.  So, I was hoping but was not sure.  Thank you!  I hope they are green coralline algae.

Please don't. Products like this can have bad side effects like bacterial blooms which effects oxygen in the water and should only be done with a good skimmer. You can also get the water too clean and starve corals. 

 

They are not really meant for beginners. It only adds more complication and things to monitor for a new hobbiest. 

 

Water changes with GOOD water are what you need. You can buy distilled if needed. 

 

Diatoms will most likely be impossible to control with tap water. I would assume most tap has silicates. The product you linked will not help with silicates anyways. 

 

Get a RODI machine and not just RO. They look complicated but I found the hardware store people helpful when brought in parts and asked them what I needed to get it to attach to my sink. 

+1 try not to introduce chemicals too much into your system.  At cycling, there's a lot of things your bacteria is doing to balance the tank.  Your job is to keep parameters stable as possible.  I know it's 4 months ago, but look at your hardware and set up.  If it has few chemicals aside from (purigen, chemipure, filter media) and it is stable, you are off to a good start.
