Diatoms. Common in a new system.
Diatoms. Common in a new system.
Like they said in "Hitch Hikers Guide to the Galaxy" "Remain calm." They are a expected occurrence in a new setup. Just vacuum them out and soon they will have exported the material they are growing on. Keep up with the water changes. They will go away. Or if they persist, there are other remedies to go to. Be sure to use RO/DI water.
We can't tell you fore sure. What do your test kits say? How much are you feeding? Use your best judgement and come up with a plan. Meanwhile. diatoms come and go in new systems. No worries.
Not needed. It's funny how many people here have recently become alarmed about diatoms in new systems. Here's the story;
Silica is a major element is much of nature. It is present in all out oceans and as such in much of the life. Diatoms are a silica eating bacteria and that is what you are seeing. Diatoms don't eat other stuff, so once the silica is gone, the diatoms will dissappear. Snails, crabs and even corals eat diatoms. That means the silica gets into their shells etc. Arogate and other coral based sands are made of coral, therefore have silica in them. That is what the diatoms are eating.
Let the diatoms run their course. The more you see the faster they'll consume the silica. Eventually it (silica) will get out of your system via your skimmer or macroalgea or get bonded into your live corals and snail/crab shells.
Great fish absolute loved mine till I took tank down to move!
That blue starfish looks like a blue linkia, which from what I have read everywhere don't do well in aquariums. They need pristine water at the very least. Not to discourage you but it will probably starve to death over a couple months as no one is exactly sure what they eat. However, good luck with it.
