Tank hits one year tomorrow

[WIReefer]

So my tank hits one year tomorrow and I started tank with all dry rock and one seeded small live rock full of coraline algae. The rocks are slowly turning purple but not sure why I don’t have any growing anywhere else it’s doesn’t blow off the rocks so I’m not sure if it is or not and I can’t keep sps alive either I struggle with it but easy corals such as zoas and palys grow fine and grow heads like crazy even have an anemone in tank for 4 months and is doing great I love the tank just not sure why she is not thriving it’s frustrating.

What are you water parmeters? Lighting? Filtration? Waterchange schedule? RODI?

One year, it should be getting pretty stabile now. Good work!

Check your TDS. When I was running a mixed tank I would always get brown algae and corals just doesn't seem to be doing good in a 2 years tank. I never ran a rodi unit as I thought 11 tds coming out the tap was good already. Switched to a 4 stage RODI unit eventually and after a couple months of using it my algae was gone and my corals looked healthier.

Should also check your par too as and acros do best in 250-350 par.

What do you mean by your sps dying? Are they bleaching or browning?
