nuisance algae

I took a sample and put it under a microscope to see if it was diatoms. Definitely not diatoms. I used live rock and live sand, and it's cycled. If it's bryopsis I want to nip it in the butt ASAP.

About a month or so ago I had a small patch of this red colored algae pop up in my tank. Every time I try and vacuum it out it spreads slightly more and comes right back the next day. Color intensifies as the lights turn on and starts to disappear as lights turn off. It's a rusty red color - not...

I am trying to figure out what this algae is in my dwarf seahorse only tank. It is on fake plants, glass, and sponge filter.

I have a very bad cyano problem in my tank and I’m looking for any ways to deal with it. I’ve dosed chemiclean four times, my mother and I have spent hours manually removing it for weeks, I’ve lowered my nutrients since I assumed my phosphate being high was the cause (and now my nitrates are too...

Hello Everyone, I’ve been having a battle with what appears to be a wiry, clumpy, red turf algae for quite a while now in my nano tank. Parameters appear to be fine with nitrates around 2-3 ppm and phosphate around 0.05. I’ve been manually removing but can only get so much out, especially with...

Blade Hybrid Algae Reactor 16 • Purchased a turf scrubber to deal with a heavily polluted tank with nitrates of 55ppm and heavy hair algae. • Tank is 92g volume so I purchased the 16 version as headroom and the 10 inch might not benefit as well due to the tank being heavily stocked. Over the...

When I first put all the macros in this tank, a dino bloom quickly came about, and it was a mess. A LFS that I frequent told me to do a 48 hour total blackout, followed by 2 weeks of daily dosing of these three products: And it very much worked, the progress a few weeks later can be seen in...

I started up a 15gallon reef a few months ago and have found every inch of my rock is covered in this fuzzy growth. It’s over a good portion of my back wall and my algae scraper too. I’ve been using saltwater from the fish store and topping off with RODI. Only things in the tank are two...

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...

I've had a 13.5 fluval for 4.5 months and I feel like I've been making every single recommendation possible to get over the "ugly stage" but I'm not sure it's the ugly stage at this point, rather than just a nuisance algae and diatom or dino problem. So my sand gets real brown during the day...

Hello. I've been suffering from excessive algae growth on the glass for about 2 months. I'm not talking about normal green film algae that needs scraping every few days, but I'm getting this strange green "dust-like" algae on my glass that starts to come back 5 minutes after wiping! No...

I cleaned the glass a couple days ago and they seem to come back every time… is there something that eats this stuff?? Yes I know I need to clean out my back chamber area … will be doing that soon What is this stuff?

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!

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...

Hey R2R! I've been having some issues with this red "hair" algae lately. I've had it in the tank for quite a while, at first it was a slow grower and since the colour is quite pretty I left it be. Lately it has been growing more vigorously and overtaking some smaller LPS frags. I'm aware that...

Hello fellow reefers, I am having a big issue with dictyota taking over my rocks. I had a sea hare that I believed was keeping it under control but they seem to have a tendency to get stuck in my fans over and over. Is there anything out there that eats this stuff? I only have a 65 gallon so I’m...

Setup my first coral QT about a two weeks ago now. I've had my DT running for 6 months now. But I haven't had any lights on the tank, since I haven't had any corals. So I didn't realize quite how quickly nuisance algae can tank over a tank. Especially one that is fresh and clean like a freshly...

I have a 2 year old tank that looks amazing in the morning but by the end of the day each day is covered (not entirely but enough to be discouraging) in a brown-tinted algae of some type that I can’t identify or can’t seem to eradicate. My nitrates are at 2 and my phosphates are at .06. (Trying...

Hey everyone, I had this algae grow in my tank initially thinking it was Bryopsis. However, I'm not sure anymore. When I first spotted it during my water changes, I just sucked it out of my tank. I decided to go all out with Reef Flux for more preventative measures. However, two weeks later...

Anyone ever dealt with curly algae before? I am battling some hair algae as well but this is different, grows primarily on rock and is thicker like a macroalgae. If you have dealt with this before would appreciate an ID and any tips on how you beat it. This is a 8 month old setup still going...

I'm just past my second month with my 15 gallon cube and getting through the uglies right now with some bryopsis and gha on my rockwork and diatoms on the sand bed. To help clean up the uglies, I stocked my tank with 5-6 blue leg hermits (hard to tell what's an empty shell and a tiny hermit...

So a little background the tank is about half a year old now. I have higher than desirable nutrients Nitrate is at 19.5 and phosphate is at .07-.17 (Hanna issues) I have a refugium going below the tank in my sump i do weekly water changes of about 35 gallons. (the tank is a 90-gallon display and...

Please help me id this bacteria on my sand bed and any experience on eradication

So this has been growing in my tank for about a month now, deep green patches, not really hairy or overly slimy, it grows only on the rocks, and it grows in expanding circles like green coralline algae does, except this is a much deeper green than coralline (I've had some of that as well), and...

Anybody know what this might be? I’m thinking that it is Amphidiniums, but was curious what others thought. It’s stringy and some are on the sand bed I think as well.
