algae

I have a new tank, around 3 months old with a handful of corals and 2 Clownfish. Within the last few weeks my Nitrates and Phosphates have both dropped to 0 (using Hanna checkers for both). These Dinos started showing up recently as well. I've been dosing NeoNitro and NeoPhos trying to get my...

is this Dinos or diatoms? It smothers my corals and comes back everyday.

Have a few clove polyps with this weird slime growing on them, had some back and fourth with a local seller saying its algae but i kight think its brown slime, need some help to identify it amd what i can do to remove it (if the photo isent clear its a lil green btw)

Having a hard time identifying what this is growing on my rock scape? Possible bubble algae? Any insight would be great.

Hello! Was curious if this was bubble algae that came with my Frogspawn frag I got today? If so, what’s the best way to get rid of it? If not then what could it be? The bubble like substance by my thumb. Dark in color. I didn’t dip my coral so maybe this was my first mistake..

Hi all, over the last couple days ive had this werid white algae form. its slimy to the touch and easy wipes off. My water peramiters are all within the good zones apart from a nitrite spike. it was zero now its around 2 - 4ppm it fluctuates over the last week. My bimedia just wasnt enough so...

I just cleaned a bunch of algae out of my sump and found these critters that look like tiny smooth (no hair or bristles that I can see) caterpillars. I’ve never seen these. In the photos they look flat, but they aren’t. They are nice and chunky. Any help on an ID is appreciated!

Hello everyone, I will be moving soon and because of that I am tearing my tank down and selling it. I filled up the 25 gallons of my tank with 1 pound of citric acid powder. All my rock and corals and fish were out obviously. I left water and algae to be killed my the acid. After about 24...

I've been battling algae back and forth since I set my tank up last December. It'll get really bad and then clear up really well for a few weeks and then come back. I'm curious what it is I'm fighting against and was hoping to get some help with ID'ing it. It gets really bad in the sand, I'll...

Hi, I’ve recently noticed this type of algae growing on my rock work and sand bed but I’m having issues identifying it. I has am appearance of bryopsis however looking under the microscope it doesn’t appear to look like it, I’ve also ruled out green hair algae as I have dealt with it before and...

Hi all, I’m having this type of algae growing all over my tank, majority of it is growing on the sand bed. It doesn’t look like green hair algae to me, this stuff feels more rough..Please help!

Hi Guys, Can anyone help ID the algae issue I’m having. I managed to get a video under a microscope, not the best of quality unfortunately. I’m thinking this is dinos and cyano but I’m not 100% sure. Thanks

For a little bit ive had this brownish red algae that has just covered my tank and some corals. Im very unhappy with the way my tank is right now and im unsure of what to do. I feel like ive tried everything so far for nothing to work. Below are pictures in normal light and white light. Ive cut...

Sorry for the noob question. Found this Algae growing on my rock when I came back from a trip. Is this green hair algae? Feels darker than that and under blue light it looks a bit more dark brownish red? The video I filmed under "Feed mode" on my Hydra 32s which is more of a white light. Thanks...

This algae been growing on my rock and back of the aquarium for the past couple month… it killed a lot of my zoas and mushrooms by covering it. I just don’t know what to do. I use chemi-clean couple month prior… I don’t know if that’s the reason why I got an outbreak like this. I don’t even know...

What’s an easy way to get this semi caked on algae off the glass? I’ve been slacking on taking the magnet to the tank. Any suggestions to get this cleaned and looking better. Obviously don’t want to scratch the tank

Hi! I don't know how to get rid of this algae (derbesia? ) when I tear it, it is like a sponge, it holds the shape of the hair. As it started to grow, my snails ate (probably low KH) I increased the triton KH is 8.3, and I am going to get animals, but I do not know what animals will eat these...

Hello my tank has been up for about 6 months now ita a 40 gallon breeder, is this cyano?

I have had recently dosed what I would call a heavy load of phyto. I dosed 50ml to a 36 gallon tank so probably 2ml/ per gallon of water volume. Also I have an oversized skimmer and only 4 fish with light bio load. I notice that usually the phyto will coat the glass and I scrape off no problem...

Hello, I’ve been batting with my tank for well over a year now. First I had the dreaded dinoflagellates specifically Prorocentrum which I beat using Silicon dosing. Since beating that I have now got GHA and it’s out of control can’t see rocks or sand bed anymore it’s just covered. Checked...
