algae

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...

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...

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...

Curious if this is Cyano mainly because it is a very bright and thick red, doesn’t seem stringy or dark red like Cyano usually looks. The hammer I picked up from somebody local, got scammed on it, and I believe that coral brought whatever tf that is into my tank I’m also confused because I...

I am considering adding a uv sterilizer to my fluval evo. I do not have any major algae outbreaks beyond what is typical such as some green hair algae (tank is 5 months) and normal algae build up on the sides of glass. I also have a BTA and one soft coral which are doing amazing. Should I add...

Is this algae? this growing on couple of dropped snail shells as well

I have had this tank for over a year and a half. I recently changed the aqua scape with Marco rock around two weeks ago. I went on vacation for 5 days and it was white before vacation and now it’s filled with some sort of algae. I had hair algae in the past, so I assume it’s partly this. But...
