algae

So lol. My LFS sold me a dead sea hare. Didn't even bother placing it in the tank, it smelled rotten. So that was the only place locally that carries them. I asked in all the local FB groups if anyone had one in East Tennessee I could buy off of them - no luck. Does anyone in this forum know of...

So basically this tank was set up last 2 weeks ago i transferred the old medias and some of the live rocks from my 55gallons going into a 120gallons and i dont know what are these cause i think it is the reason why my water is a little cloudy because of these microbubbles coming from the rocks...

Hi all and thanks for the great read found in this community. I’ve been fighting with this brown algae issue for a while now, my tank is about 5 months old. Nitrate stable around 15, alk around 7, phosphates near zero but struggling to increase it, protein skimmer in action… not sure what my...

Hello! I’m new to the hobby, and have had my 40 gallon saltwater tank since October 2024. Recently I have had my first algae breakout and am struggling to identify the algae, cause, and next steps. My Nitrates & Nitrites are 0, I have no way of testing Phosphates at the moment. I was doing my...

Hello all, I’ve recently setup the tank of my dreams in my home 2 months ago. This past week, I noticed i’ve accumulated a brown algae that has taken over my whole aquarium. I just ordered a microscope to see what it really is up close, but was wondering if anyone could ID it, or give the best...

I know the pic is fuzzy. Noticed this fella cruising the glass tonight and definitely eating algae. A limpet of some sort I believe. Pretty sure I’ve also seen him stuck to the glass under the sand bed as well. Anyone know what he is and if I should be concerned?

So I noticed this blue squishy substance attached to the bottom half of my snail’s shell. The top is covered in coraline algae. After researching for quite a bit, I am now convinced that it may be some sort of blue sponge.. maybe a plated blue sponge ? Anyone have a clue?

After some travel (excuse the green on the back of the tank) came home & was looking at my rock & saw these guys?? Any clue what they could be? only have soft corals, snails, herms & clownfish in the tank, but got some corals a few months back from lfs & probably had some hitchhikers, help would...

Hey all. Can anyone id these green tubes and is the red on the rocks coralline algae or red slime?

I thought it was a bacteria bloom until I changed my lights to white. Ammonia, nitrite, and nitrate are all normal, as well as salinity and temperature. All my livestock looks healthy, and I do a water change with gravel vac and clean the filtration materials (in saltwater) weekly. Should I...

Hello, all I have had quite the GHA algae that just keeps coming back I am waiting on more test strips to get a better idea of why it keeps growing so bad. In the meantime what does everyone recommend for LONGGGG GHA like 3-4INCH I have big Mexican Turbos, Smaller turbos and the algae on the...

Hi all, This tank is new to me as of 3 months ago, but was up and running for over 2 years and i didn’t take it down. It’s a 10g jbj AIO with global nano 2.0 LED lights. I was recently gone for Christmas for 2.5 weeks and had an ATO failure. Thankfully i had a camera on the tank and a nice...

Hello Fellow Reefers Let’s start off with my story. I have a Waterbox 25 Peninsula. It is an AIO and has been up and running since late May/June. I have now stumbled across some sort of algae issue. I am unsure if it’s algae or dinos or something else? I’m going to be honest I got lazy with...

Hi all! I’m quite new to the reef tank world. So far I’ve kept a clownfish, favia coral and strombus snail on a 45 liter tank. All is well so far and water parameters are good. I’m now introducing a trochus snail, a skunk shrimp and a hammer coral. Different random algae has been growing on my...

Sorry for the crappy photo quality, looks like small plate like algae that is growing all over a rock. Also small strands coming off of it. Thanks for any help!

Hello, I started my tank in October and took a 45 day break as I was doing a fallow because of brook. I am using RODI water. Don't know where the start of the diatoms is so I am just planning to get a Clean Up Crew. I have 1 bumblebee Snail that was a hitchhiker from one of my coral. My tank is...

I am struggling to get my corals and rock looking healthy. Tank has been running for about 8 months. It took me awhile to learn about how to keep proper nutrients and for the first 6.5 month I was running with 0 nitrate and 0 phosphate. My corals were starting to brown and had no polyp...

I am running an Eshopps 9.5 gal. bi-level nano tank. This is my first saltwater aquarium and have had running for about 1 year. I started with live rock and live sand with two clown fish. All of the corals I have glued on the top tier have died. Usually within a month or two. In the...

Hi everyone was hoping to get some help on identifying this green leafy algae that been driving me crazy. It grows in short tufts and has a curved leafy appearance with a lime green color. It attaches very firmly to the rocks and won’t fully come off even when scrubbed vigorously. If I try to...

I have this algae (or possibly something else) that’s on my rock and on corals. It doesn’t easily blow off and in fact is very difficult to remove. It’s likely not cyano as I just did a treatment with chemiclean and it didn’t help at all. Any ideas and how to rid my tank of it? Lowering...

Hi! First of all, I would like to thank you all for your help! Whenever I have a problem with my tank, you help me solve it ASAP! Now to the issue: In the past few days, I noticed that a white spot appeared on the top of my clownfish. I have no idea what this could be, so I want to hear your...

Trying to overcome my agae woes. All (98%) of my long hair algae is gone in the display tank, but now I have a stubborn Turf Algae growing. I saw videos of people suggesting spot treating each day where roots are more stubborn, but some threads on here seem to have me believe there is no such...
