Brown Algae On Glass

If this has been covered before (I'm sure it has) I apologize. I am new to the site and haven't been able to navigate it well yet. I have a 14G BioCube that has been up successfully for a couple months now. Live substrate, plenty of Live Rock, a feather duster, Ocellaris (1), Watchman Goby (1). I recently added a piece of Live Rock that was covered in polyps. My problem is, I am beginning to get a brown algae on the glass and I cannot figure out from internet searching whether this is a good thing or a bad thing. The shop sold me some Reef Accelerator I use once a week. I also add "Vitamins" and Cycle when I do maintenance. With the purchase of the polyps and Condy (Condy is dead now) I picked up Iodide as well. All "chemicals" are used sparingly. Lighting is stock and on from 530am-1230pm. The only water flow I have at the time is the stock pump output directed towards the polyps.

Ease my mind or let me know what may be causing this algae. It's not horrible just some dusting on the glass every few days I easily remove with a magnetic cleaner. Any help is appreciated, thank you.

 

I'm not completely sure what kind it is, but I have something that looks the same in my tank. I haven't seen anything that looked like it was bad, although it is ugly. Are you using RO/DI water or tap?

 

I wouldn't dose iodine.

It's likely diatoms, which will bloom and disappear once the silicates are removed. Anemones need a very established (possibly a year) tank, so that may have been its downfall. Either that or elevated iodine levels.

 

It's probably from the new rock you introduced, same thing happened to me. Just cut back on feeding and do some extra water changes. Also make sure you top off with RO/DI and not tap. Astrea snails take care of most of the algae.

BTW, I would invest in ATLEAST another powerhead (koralia nano 425gph is a good one). You shouldn't dose what you can't test for either. If you want to keep more anemones in the future, a lighting upgrade is neccesary.

 

yes, I would recommend to stop adding your extras - I bought some items in the beginning of starting my fish only to reef adventure and found out that adding them could cause more harm than good. The bottles make them sound good and necessary but they are not ....the brown on the glass is probably diatoms as others have said, nothing to be concerned about.....
