Not sure if this is the right thread for this (still learning to navigate this cite). So, I’ve reached the point in my young reef tank commonly referred to as the unholy stage and realize that there is nothing I can do to stop it. Have read hundreds of threads with great info, thank you to those folks. In the last two weeks diatoms began to spread on the rocks mostly, some on the sand which my diamond goby is taking care of. Some things that I have read will help is trochus snails, which I plan to get tomorrow ( my fish store is closed today), and RODI water for water changes. Which sadly I don’t currently have but working on getting. I have a coraline x12 36W UV sterilizer currently installed. My dilemma is, do I use seachem phosgaurd? I’ve ready that it can help reduce the growth and possibly eliminate. All that for my question. Do I use the phosgaurd or just let the tank be considering it’s new (just over 3 months). Thank you in advance.
