brown algae

I recently started up my tank about 6 weeks ago and have now gotten this algae outbreak out of no where. It’s brown algae across the rocks and also across the sand which has been a nuisance since it’s constantly seems to come back. I also seem to see a weird haze in my tank but only really...

Hello everyone. I am currently dealing with a problem with my 48 gallon tank. The tank has been cycled for about 3 months now. I have 3 clownfish, 1 anemone, 1 mushroom and 2 acros....Since last week, my tank has been filling up with brown algae and i cannot get it to stop overtaking the tank...

Hey guys! I’m a new reefer and I believe what I’m experiencing is Diatom algae which I’ve read that just letting it play its course is what I should do. I do have some green algae starting to grow and hopefully that will cancel out the Diatom (if that’s possible). I’m just looking for...

I have a reef tank that most likely has either brown diatoms or dinoflagellates growing on the gravel/sand. Tank is at least a year old. Tests indicate excellent water quality with the possible exception - API kit shows nitrate @ 0 & phosphate checker shows it @ 0.03 so maybe too low? meaning...

Can someone help ID and let me know what I should do. I have this brown stringy algae on my tank bed, some pieces starting on my rocks and a little on my coral. How do I treat?

Hi there, brand new to the hobby. Bought a 32 gallon Biocube to “keep it simple” but have something fun and new during quarantine. But then when I learned about water changes and water parameters and such, bought the APEX system to automate the tank so I could take good care of the new pets...

I'm about to lose my mind over these dang diatoms guys! I'm a little over 2 months in now to my new saltwater aquarium and everything has been doing great, finished my cycle about a month ago, put a pair of clowns in a week after that and over the last few weeks have now gotten all the fish I...

Hello, My tank has just finished its cycling period and has perfect parameters to start putting fish in but I just noticed this brown diatom forming. What do I do now? New to this hobby and am posting this so I can learn from you guys! Thanks in advance.

shortly after I bought this Scolymia, it started to turn brown in some patches. Mind you, I've had the coral for months now and it hasn't died, but it doesn't look the gorgeous bright green that it did when I first bought it. Can I fix this? I've not had any brown algae issues in the tank, if...

Hey Reefers- Been battling BJD for about 3 weeks now on one of my Australian yellow hammers. It's been slowly losing flesh for a few weeks and looks to be coming to it's last days. This will be the 2nd yellow hammer I've lost to brown jelly. Weirdly enough, it's only been the yellow hammers...

I restarted my tank around 6 months ago and it is going well. Nice and stable, corals all growing well including SPS. No3 2-3 Po4 0.06, ICP all good ( except tin is a little high) NDoc all good. I have however, got this annoying brown fuzzy algae on just the rocks and the rear overflow box. It...

Hey #reefsquad, I noticed my grape coral frag had some of this brown algae stuff growing on it. It doesn't seem to be getting any better so I was wondering what I should do??? Nervous that it will spread to neighboring torch corals so please help!! Thanks so much!!

I've been battling brown colored hairy algae in my tank for a few months now. I need any advice I can get. My tank is a RSR250, originally set up in December 2016 (so 16 months old now). I have 2 Radion XR4 HD lights with a personalized schedule (mostly the coral lab LPS setting but added white...

Just a list of items I'm trying to thin out the tanks. The more you buy the more you save. If your not sure what a item is pm me for a reference.

Just finished a chemiclean treatment which (so far) seemed to work pretty well. No bright red cyano and the rocks look great. But, I'm left with this brown algae on the sand which I'm guessing is not cyano since it did not respond in any way to the chemiclean treatment which included a 48 hour...

Hi all. My IM Nuvo Fusion 20 gallon mixed reef has been up and running since its cycle completed in mid-October (~2 months). I have a pair of ocellaris clownfish and a handful of mostly LPS corals. All seem to be doing well. I also have 5 cerith snails which will come into play later. About...

I have recently had the emergence of brown algae on my sandbed that has coincided with some other inconsistencies in my 180. All within the past month, I have had: Emergence of Diatoms, mostly on sandbed. darker in some areas, non existent where there is no light (under rock/coral overhangs...

Day 17 of cycle. Tank has a lot of brown algae which I know is supposed to happen. I think I just need to hear it from someone other than the voice in my head. LOL Also, I've read so many differing opinions on cleaner crews I'd love to get y'alls opinion on how many, types and when to add...
