brown algae

Hi all I’ve recently cycled my reef and my water parameters are starting to settle I have been experiencing some brown algae on the surface of my tank and the substrate has been turning a brown colour only a day or so after cleaning I’ve read it could be diatoms but not quite sure if that’s the...

Hi all, I have this brown stringy algae growing on my rocks and my sand. I’m having trouble determining if it’s just a brown stringy algae or dinos. As you can see it’s growing in and between corals, likely irritating them. I tested nutrients yesterday and Nitrates are 9 and phosphates are...

Hello! I have this weird brown algae growing on some of my corals. It looks like it could either be dinos or brown hair algae but it only grows on a few of my corals plugs and only a couple spots on my rockwork. The tank is about 5 months old. I run a protein skimmer just did a 20% water change...

Tank is approx 1.5 month old. waterbox cube 20 Floss > chemipure blue > poly filter pad. Video for attention. Dragon Thorn Turbo snail putting in work on my first brown ugly phase. I only clean the 3 sides.

This is currently what my tank looks like Question 1) the brown algae -read a lot about it being good, but how much is to much? I also have green algae on my glass. Question 2) close up of rocks with micro bubbles - is this okay? Question 3) should I be running lights on a normal day/night...

Hi, I have a Tang and he's been in my tank for about 2 weeks now. He started getting discolored spots. I have done many google searches and can't seem to find a photo or description that exactly matches. I've seen that it could be ich, an infection or just from stress, so I thought I would just...

Hi all, I added some old dry rock a couple weeks ago and I started noticing a couple days ago a brown film on them. Today I can clearly see it is like a brown slime. They have some tiny micro bubbles starting to lift it so I can definitely see the slimey-ness. The rocks I added were some old...

Hello fellow reefers, I have what it looks a case of brown something. I believe is not Dino since I don’t see bobbles on the string and my parameters are Nitrates 11 , phosphate 0.18 alkalinity 11.3 and calcium 420. I know they are not the best. Any idea what is this and how to fix it

When i try to scrape it off it disperses like sand. Everything is turning brown, even the substrate and glass. I tried buying a phosphate test buy i could find it here so i’ll try and see if an aquarium store can perform the water tests. The ammonia is at 0.25ppm and salinity at 1024

So I’m new to this hobby , my tank is roughly 3 months old, besides having a big bacteria spike due to me over feeding *which I fixed with a HOB aquamaxx1.5 skimmer to assist my Fluval filter*, I haven’t had any other problems with the tank until now. 2 weeks ago I started noticing possibly...

I’ve set up a new 25g tank and I’m going through the dirty stage. Got like this brown algae first thought it was diatoms however when I turned my LED to a more higher whites I’ve noticed that the algae looks green? Is this still diatoms? Picture is algae under whites, looks brown under blues. ⬇️⬇️

It's all in the title. What brown macroalgae do you own? Please post pictures! Edit: Include those you have owned as well.

Hey another question, definitely have an emergency on my hands and need to know what to do ASAP. As much input as I can get would be appreciated. I have a 29 gallon tank about 3 months old housing two ocellaris clowns and a bunch of mushroom corals. 3 days ago we added some new tank mates 4...

Hello! New here and new to the hobby. We have a 33g Cube that’s been set up since January. We successfully housed 2 clowns and 3 hermits since March. At the beginning of May, we added a Pajama Cardinal, Sexy Shrimp and carpet anem. Last week, we went out of town and did a water change...

Hi.. My Biocube 32 tank was new and I added fish 3 days ago. While it was in cycling i did not turn on the lights. I am using lights for past 5 days and now i see brown algae on the sand bed and on the side glasses. Can anyone please help me to get this clean. .

Have some snot on the back glass, that's growing in an interesting pattern. It's ONLY growing on the glass, and both the turbos and nerites are eating it, so I don't think (fingers crossed) it's dinos. Some of the strings are nearly a foot long, but no bubbles. Where it's growing best is on the...

I have been extremely patient going through my cycle and it’s been quite fun but I’m tired of it! Does anyone know when the different types of algae will start to disappear? my tank is 6-8 months old and my nitrate is sub 5 ppm. Also, how can I control green hair? it’s getting bad..

I’ve been googling away trying to figure out what this could be with no luck.. one thing to note, the tank has been without water changes for a solid 4-5 months. That’s besides the point, I just want to know what I’m battling I do believe a shrimp/goby pair died in the tank shortly after I put...

I've had my tank running for a few months now. I cycled the tank with microbacters cycling kit, the cycle went great and was done within a couple of weeks. This sort of dust algae appeared about two weeks ago and then some GHA. I added 3 emerald crabs to keep up with the hair algae but now the...

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...
