algea

Tank has been up 3 months or so. Not quite sure what this is. Was hopping it was a quick and easy id lol. It’s not hairy or anything just turning the rocks green I was fighting off brown string algae for about a week then this started to grow. Cuc doesn’t seem to eat it and lawnmower doesn’t...

My tank has been up for almost 2 months. Went through a very short diatom phase, i still get some on the glass. Now there is some greening happening but there’s no algae coming off it. What could this be? Disc Mag 1320-1350 Calcium 440 Alkalinity 9 SG 1.0255 Phosphates 0.02 Nitrates 10 Temp...

I am new to saltwater my tank is a 55 gallon, it was set up with live sand, all dry rock, cycled out, then a green spotted puffer was added, a purple dottyback and a damsel fish. I use instant ocean reef crystals for my salt mix, my Temp stays at 81 degrees and my parameters are staying stable...

hello all I am new to reef2reef and I’m having a little trouble, I am dealing with some pesky, what I’m thinking is either Dino's or Calothrix. I’ve been trying to get nutrient levels up but can’t seem to. Can’t even keep Cheato alive which I’m assuming with a new-ish tank this is going to be a...

Hello all. I’m new to this hobby and believe me I’m in love. But being new I’m still trying to grasp the ropes. Definitely a learning process. I have a Fluval Evo tank. I’ve had this tank with fish in it for 2 months now. I’ve been struggling with this hideous algea red and green. On my rocks...

My corals have been looking rather sad for the past 1-2 weeks. Tank: 6-7 months old, 35 gals May 1: Bacterial Bloom. Cleared up and dropped nitrates to 1. They are typically around 10-12 since I mainly have LPS corals. May 12: 5 gal water change and cleaned all the algae off the back wall for...

Wanted to share the some hope. Bought a Craigslist reef with loads of algae and diatoms and nasties. Rip cleaning after reading threads on here. With peroxide scrubbing of rocks (not all at once) Raising nitrate but expected because I’m working on raising the good bacteria I lost. Here some...

What is this algae called and how would I get rid of it

Hey guys, So i have a 40B Parameters are ALK: 12.5 CALCIUM: 430 MAG: 1230 NITRATE: 11.3 PH: 8 PHOSPHATE: 0.33 I did just change from Cora life to red sea coral pro salt. And the only new addition to the tank is chaeto. I did have a coral that died but i took it out of the tank once it went...

These patches are popping up along the rock along with these new patches of white is also some coralline growing around the tank. The texture of these white surfaces is that of rock so not slimey at all. What do you think it could be?

My clownfish tank since day one has been overrun by green algae all over the glass even after water changes for months and less feeding it comes back within days i need help to what i can do to stop it. Ph-8.2 Nitrate-20 Nitrite-0 Ammonia-0 Salinty-0 Fish stock- pair of clowns, cleaner shrimp, 4...

So, I have had this 13.5-gallon saltwater tank kit for a few months now and its never stops having loads of algae in it. I do water changes every week from the water from my local Petco, but I also have my own ROM but it's too cold to use it since I connect it to my hose into my basement. I just...

Hi again. So my tank is around 4 months old now and been going through all the uglies. I am happy taking things slow and really not bothered about the uglies all that much. It recently went through a massive GHA bloom which I mostly left to its thing while manually removing some and it’s now...

Hey there everyone! I’ve had my mind made of for a while on getting a orange diamond foby for sand sifting. I’ve been told also that if I don’t have enough algae growth it could potentially die and rather fast in my 24g nano … what are some options I have besides snails. Which shrimp would serve...

I have some brownish stringy algae on the sand bed. Here’s some scope pictures with a link to the video. One person said diatoms already but I’d like to get that confirmed. Thanks! https://youtube.com/shorts/bIbPYK4BhB4?feature=share

Hello, I’ve had brown algae for months in my tank and I believe they could be dinos from all pictures and descriptions ive seen, however I’m still not sure. Can anyone help me ID these??

I have been consistently getting 0 on Nitrate and Phosphate. I have chaeto in a back chamber that’s literally doubling in size in about a weeks time. I give it 18 hours of light which I’d read was recommended. I also have green hair algae forming on the sand. As of yesterday, my ammonia level...

Ok I’m not sure what kinda algae this is. I was thinking dinoflagellates but I’m kinda puzzled though as I don’t have a ton of bubbles like traditional dinos and I have nutrients. I did a 10% water change last night I’m pretty religious on weekly water changes but this one was closer to 10 days...

I've had my tank for 5 weeks now, and I've noticed something growing on my xenia. Can any tell what it is?

I have a biocube 32 LED with a current cuc of 7 astrea, 4 cerith, and 5-8 nassarius (I have no idea how many I have they breed all the time), and 3 hermits (1 dwarf red leg, 2 dwarf blue legs). I have a lot of red slime and dust algea still and he hair algea is slowly being eaten by the astreas...

I have regular purple coralline growing on my rocks. I also have this very light blue colored algea that looks similar and a hard green algea on some of my other rocks. Are these coralline? Also some white colored areas on my back wall. Is that the start of coralline?

Hi all new to the forums. I've searched a bit, but have not found quite what I was looking for. Or if I have it's been worse then the stage I'm at. But as my title states, I have a BioCube 32 that's been up for just about 3 months. It's been a month since diatoms have disappeared and all seemed...
