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...

Newish nano tank, couple sps coral and few lps. Algae has gone bit nuts and is starting to go on my sps. Will update shortly with water parameters

Hi I'm going through the ugly stage now and my tank has 2 clowns and no corals (yet). Is there a way to end the ugly stage early or speed it up

How to best help this guy? How worried should I be? Seems like the only one truly affected at least to this extent

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...

Hi all just wondering if someone can identify this brown substance on my substrate I have tried removing it 3/4 times but seems to be coming back is it algae/detritus if so how can I get rid thanks

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...

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...

not sure if this is a hair algae. It seems to have leaves rather than just hairy. Also the second one is clear and just floats and moves with the current so it’s definitely not an animal or critter. But what is it? Any ideas? Thank you!

I just returned from a trip and discovered a lot of long algae in my reef tank. Could you help me identify these and advise on how to get rid of them? They are damaging my corals and clam. Thank you!

Looking for personal experiences of reefers who started out using tap water in their system and then switched later to RODI. Curious what problems you had before that the RODI fixed, issues you had that were not fixed, or even changes you experienced with your parameters afterwards. For me...

Howdy! I have these two Gonioporas and that have some algae growth happening around them. How do I remove it without being to invasive?

Can anyone tell what are these bubbles? You can also see then at the frag rack.

This orange Algae started growing and sprouting and bubbling all over my sand and now it’s almost everywhere. My protein skimmer it picking it up and starting to fill with the nice orange gunk. What is it and how do I clean/treat it. Also on this same subject what is the best tool out there...
