algae

This is the back wall of my 120g (lights are off right now).I’m fairly new, only started a year and a half ago, and this tank has been up for just over a year. Whenever I preform a water change, my girlfriend says she doesn’t want me to scrape the back glass because she likes the look of the...

This white branching algae (almost helpfully displayed on the old frag plug) has popped up in my tank in a few places. I wasn't too concerned about it at first, but it seems to be irritating my zoas and ricordea. None of my CUC seem interested in eating it. Any idea what it is? TIA.

Tank is about 6-7 months old had my first Diatom bloom 3-4 months in and it went away. Shortly afterwards water got super cloudy and GHA bloom came overnight. Added a UV filter to my sump and beat the GHA. Now I have Diatoms covering the whole substrate surface... when I first setup the tank I...

USED for about 1 year. This is the PaxBellum ARID n24 Algae Reactor. This is the best algae reactor money can buy. An absolute beast. Also very visually attractive. I bought this used, but it worked too well! Decided to go a different route as a result. Specifications: Recommended Aquarium...

Hi everyone! Newbie to keeping tanks and about 7 months in to owning! I love it and my tank is doing great except for this pest of an algae problem. I do weekly water changes and clean up the algae on the sand but it keeps coming back. Could it be diatomes? I’ve included 2 photos one with blue...

I've been fighting a losing battle with hair algae for close to a year. The tank is a JBJ 29 Gallon nano. My brother had it setup for years and stopped taking care of it and algae took over. Hair, bubble, caulerpa, it turned into a refugium more than a tank. He finally broke it down and it sat...

Hi all, I recently have been trying to figure out a way to use an ultrasonic transducer to clean off year old coralline algae that is incredibly strong. Normal plastic scrapers don’t do the job and metal ones will cause scratches. Attached is a video of a test I did using a handheld dental...

Mods please delete this post, wrong forum.

Hi all, Here's a picture of our 4 month old tank at the moment. We have a lot of brown going on and I'm trying to figure out whether it's diatoms or dino and whether I should intervene or accept this is part of the ugly stage and let it be? We have corals in there so don't want them to be...

is this stuff just hair algae or something i should be worried about

I've had a huge buildup of green hair algae on the back glass of my tank. I scraped all of it off, and added some snails to keep it in check. I've noticed that the algae growth on my live rock and sand has gotten a lot worse, and the snails/hermit crabs don't seem to be helping. Any ideas how I...

I've had a Fluval 13.5 for exactly 1 year now. 6-8 months in, the tank was thriving. 2 snowflake clowns, several corals, inverts. On month 9-10, dinos hit. I mostly kept it under control but not before losing a few corals. Inverts died off quick and anything new I added was dying instantly...

Hello everyone, I've had the tank running for a year and I had a crazy high Phosphate 4 months ago. Hannah checker did not even read it as it was royal blue.(200+). Started running gfo and made water changes weekly. It got to a readable amount and ive gone as low as 40 on the checker but im...

Every few days my back wall is covered in these things & in a few small random sections of the tank and sump. They stick on as well. Is it a bacteria or something more sinister.

Hi everyone, recently I started seeing these red spots, then noticed these hair-like strands waving from my rocks, can anyone help point out what they are? They look a bit like cyano but I don’t know for certain. Thanks!

Unsure of where to post within a forum.. What snails are recommended for tanks? As a good CUC. What snails eat hair algae? I have been trying to find more trochus snails as they can flip themselves over, but I haven't found any the last few months. I have 4 and they basically stay on the...

I have an My friend has an IM 20P Pro AIO. It's been running for 4-ish months. I am having My friend has a diatom problem, been treating it for a few days. Of note, I also have My friend also has an EVO 13.5 that was set up at the same time with the same salt, water, etc. No diatom bloom. 3...

Will no lights kill bubble algae? I’ve tried everything to remove bubble algae and nothing has work so far. What I’ve tried Reflux Emerald crab Foxface And manually removing 95% of it Just for everything to rapidly grow again I have two more plans: 1. If I remove the rocks and scrape off as...

Can you please name and tell about these 3 guys, so if something, i can get them out before they spread

My parameters are all normal -0 Ammonia -0 Trite -0 Trate -1.025 -77.5 degrees -AI Prime HD set to SPS AP+ spectrum -AI Nero3 pump set to random mode between 3% min and 20% max with medium variance, and it blows straight at the back rocks and diffuses it everywhere along with return pump flow...

After cruising the internet looking for solutions to hair algae, I came across the seemingly magic solution known as blennies, and then realized there's dozens of varieties that all seem to be their own fish. As with everything in the hobby, there's no perfect fish, so I imagine there's pros and...

For those who don’t know, I recently got someone else’s established 20gal set up with two clowns and a blenny as a complete beginner. This forum has been a godsend and I appreciate you guys so much. Now for todays question: how do I clean these rocks? Will scrubbing with a toothbrush in clean...

So I used feed my whole tank Rod’s frozen food and then would put a piece of nori on a clip for my foxface, which would be the only thing that showed any interest in it. Now I have a pigfish (type of grunt) and that thing certainly lives up to its name. It will swim up and rip the nori off the...
