Hello everyone. I have attached 3 pictures of this white stringy stuff that appeared two days ago in my tank. I assume it is bacteria? Can anyone confirm or correct this? Thank you!

What is this thick white spider web like stuff on the live rock? What can I do to rid it?

Hey fam! So I’ve cycled many tanks and this is the first time that I’ve cycled using ammonium chloride and Dr Tim’s… not sure if this is because of it but my tank is cloudy and has a white powdering kind of substance on glass walls and pump as shown in the pics. I know a bacterial bloom but...

Hello! I will summarize at the end and provide photos if you don't want to read my initial tank journey from start to now, but here we go! I included the journey only because maybe there was a misstep I took that can explain things. Look for the colored markers if you want quick notes, and...

Fairly new to hobby, have only had the 75g tank for about six months and have had two clownfish and a couple astrea snails and hermit crabs in the tank for about a month now. I have diatoms and little tiny white algae’s,(sponges?) on in the tank that’s a bit out of control in spots I’ve resorted...
