Help please

Hey there
I have a new saltwater aquarium that's been running for about 6 weeks. Just wondering if this is normal? And what I should do?

That is algae. Its normal in the cycling process.

Do you have live stock in it already?

We have a clownfish as of yesterday.
Do you know how long it takes for it to go away? Some say a week, and others say it might take months.
Thankyou for your reply 😀

I wish more people had Nielsen and Fossa's "The Modern COral Reef" Vol 1. It has a chapter showing the various algae cycles during the first 8 - 12 months while an aquarium matures. What you are seeing is to be expected. The only thing I would do is manual removal. Here's some videos I think you might find informative or helpful:

Your rock and sand (and water (if you didn't set up with ro/di water) ) can bring in phosphate, which is fertilizer for algae, which can start from spores on rock, or in water, or, I'm convinced, even in the air---I used to live on lake, and I swore it was the case. Every tank tends to get it and to get rid of it, you have to get it out of the water: use ro/di only. Use GFO (Phosban and other brands) and use a lot of patience. Forget getting anything to eat it: the poo dissolves and breaks down and your phosphate is right there---again. Has to be removed and kept out.


Salinity 1.024-6; alkalinity 8.3-9.3 on KH scale; calcium 420; magnesium 1300, temp 78-80, nitrate .2. Ammonia 0. No filters: lps tank. Alk and cal won't rise if mg is low.

Current Tank Info: 105g AquaVim wedge, yellow tang, sailfin blenny,royal gramma, ocellaris clown pair, yellow watchman, 100 microceriths, 25 tiny hermits, a 4" conch, 1" nassarius, recovering from 2 year hiatus with daily water change of 10%.
