algae

Hello, I know it’s hard to see, but I have these little plants or algae or whatever they are growing on the glass in my salt water tank. Are they bad? Should I evict them? Or are they good for the tank? I honestly have no idea so someone please let me know. Thanks.

Hello all! I’ve attached some pictures below of an algae issue in my 75 gallon 7 year old reef tank. This issue has happened ever since we got a new light- the blade coral grow. We had no algae before this light. The tank experienced a whole lot of coral growth with the new light followed by...

Hello. I have this algae growing in my dt that glows bright red under blue light. Unfortunately i cant show this because my phone camera doesnt show colors in blue light, but photos in whiter-light are attached. I would like to get rid of it as it is growing all over my sand but i dont know...

Hi all, for the last 11 months I’ve been having serious algae issues in my tank that I just can’t pinpoint how to get rid of. It’s green/brown in coloration and will either appear as long hairs on the sand and rocks or just as a fine layer on the sand. Snails and hermits don’t seem to touch it...

Hey everyone! So this tank has been up and running for about two months now. Everything was going smoothly at first, but then my auto feeder accidentally dumped more food than it should have—and I didn’t catch it right away. Next thing I knew, I had a bloom in the tank. I added a UV...

Can anyone tell me what kind of algae this is? Its been growing in my tank for the last couple of years. Since it doesn't bother the fish and I was in college, I couldn't really keep up with maintenance so it is way out of control. It built up along the entire sandbed about half an inch to an...

What kind of algae is this?

What algae is this?

Hi everyone! Could I get an algae ID on these specimens I pulled out of my system? TIA!

Hey everyone does anyone have an idea what this algae is? Is very easy to pull off the rocks, but it also forms in balls on the sand. Don’t have any idea what it is and it just showed up about a month ago. If someone knows what it is, what is my best solution to fix it? It looks reddish...

Hi Guys have had this outbreak and been trying to get rid of this algae for 2 months. I have tried 50% water changes Reef Dynamics Vibrant Any advice or solutions anyone can offer. I added a video. Thanks

Hi all, I have been battling with nuisance algae for about 2 months now. I noticed it start to build up when I started to dose Red Sea Reef Energy Plus. I stopped dosing Red Sea Reef Energy Plus and began to dose Microbacter clean. I am on about 2 weeks of dosing MB clean. The past 3 days I...

I have this dark brown/black algae? On my rocks. I’m pretty sure it came in my system from a fragpl plug. It is encrusting and doesn’t come off easily when scraping. It does feel a bit soft to the touch but it doesn’t seems to be a sponge as it is not plump or does have any holes or intake on...

Hey everyone Ive been struggling to figure out what is growing on my live rock. I have a 150 gallon FOWLR with a 60-gallon sump that I've had for 2 years. I have a long spine porcupine puffer, red coris wrasse, harlequin Rusk, majestic angel, 5 lyretail anthias and a snowflake eel. My parameters...

I’m growing monti on the back glass and the algae had stopped it from continuing so I started to remove the algae directly above the monti. If I physically remove all the algae at once on the back glass are there any negatives that could happen?

So I've had this white/brown slime stuff for over a year now. It started as a thin layer of almost slightly fuzzy white slime on the highest rock surface in my tank. Didn't seem much to worry about at the time. It got worse over time, and for the year this stuff has been covering every single...

So I got a microscope because I have been dealing with what seems to be Dino’s on my sand bed. In the video there are these things racing around SUPER fast. Are those dino? If so. What kind?

Hello I have an 250 gallon fowler aquarium it's been up and running for about 6 years well this tank is a year old but the rock and fish were transferred from my last system of 5 years.. this started as a small dime patch a quickly spread. I did add an aqua uv 57 and started to lower my...

Alright boys let’s play a guessing game. I have some pictures and I’m wonder what you all think. I have a microscope coming tomorrow to confirm. DINOS? DIATOMS!?

Hello, I need someone's input. Been reef keeping a while now. But this is the first time I encountered this algae. The tank is a 155g shallow including the sump. It'sbeen up for about 2 months now. I know that diatoms are a thing for new tanks but this is the first time I saw this. it looks like...

So i have this algae that appears slimy on my rocks and kind of comes off in sheets. I was worried it was dinos but doesn't look like that. Under the microscope I see this: Can someone confirm whether or not this is some form of filamentous green hair algae? Just seems super small to be that

Hello everyone! Fighting my first Algae Bloom: Almost no visibility within the tank. Is this harmful to the critters? I was told blacklight can damage certain animals but was unsure. I replaced about 10 gallons of water today and did a 50% change yesterday. Was hoping one of these would...

It grows in small circular spots like this and is hard to scrape off. Only a razor works.

Tank is about 5 months old. Nitrates and ammonia are slightly high but nothing crazy. Are these Dino’s? It did get worse after a water change. My nem seems not to like it very much. What do I do?
