bacteria

Found these tiny critters under my algae scraper, not sure what they are. Does anyone know what they are? Hopefully you can see the video I posted with this.

Hey guys. I’ve noticed this white splotch on my purple tang recently but did not think much of it. Recently my powder blue tang died, i’m unsure of the cause, but I remembered that the powder blue tang had a similar white splotch a week or two prior to him dying. I’ve attached photos of both...

What am I dealing with here guys? It’s starting to take over the tank. Appreciate any help

Hi Everyone, I have been battling Dinos in my tank. I plan to increase my nutrients in my tank. I have Neophos and Neonitro. Brightwell recommends adding Microbacter7 with these products. Why do they recommend Micorbacter7 in conjunction? Can I still not add MB7 and have the same results ? Thanks

Hi guys can you help me identify what this is and recommend treatment? Currently it’s in a 75 gallon qt tank running some copper under .8ppm and I dosed knaplex and metroplex as well as prazi in the past 2 weeks, running carbon at the moment.

Hello reef friends and experts! I was wondering if anyone could help me identify this type of dinoflagellate. On the sand bed, it looks more like diatoms. No appearance of stringy/snotty bubbles, just brown patches that appear during the day and vanish at night. Under the microscope they are...

Why does Cyanobacteria get such a bad rap? I haven't dealt with it personally. From what I read it creates Cyanotoxins, steals oxygen, which in itself is bad. But people make it seem like it's the biggest nightmare of their lives! I've heard it can be caused by a multitude of reasons, ranging...

I have a 75g aquarium been running for a couple of months now, I cycled the tank with the microbacter starter kit and it went well. The starter kit also came with a bottle of microbacter clean, to use over the next few months to battle through the ugly phase. The ugly phase has begun and hasn't...

SPS tissue degradation and loss, whether its slow (STN) or fast (RTN) or associated with a brown gelatinous mass (BJS) are probably one of the more or even most frequently discussed topics here. A particular emphasis is given on the „help“ requests describing the fast peeling and patchy loss of...

So I had a green hair algae outbreak, then an ammonia spike, I dosed kordon AmQuelPlus ammonia detoxifier, it kills ammonia nitrite and nitrate, and chlorine. Things started to bounce back. I lost 2 cyphastrea, and a birdsnest, during that ammonia spike, it went to 0.50ppm. my xenia has been...

Need to know what this is so I can treat it correctly. It’s only a photo but they move around quickly. Thanks

Hello reef2reef community I recently made my dream transition from fresh to saltwater. My setup is a 14gallon (52L) IM peninsula with dry rock and live sand on day 34. The current equipment on the tank is an ato, biopure gems and recently added my skimmer to begin nutrient export and breaking it...

First post, need help.... Can anyone tell me what this is and how to get rid of it. My Phosphates .04 and Nitrates 5. Been doing 25% water changes weekly using RO/DI water 0 tds.

Set up my first saltwater tank, a 90 cornerflo! A little cloudy bc I only had one clarifier packet, but I’ve dosed it w dr tims ammonium chloride and microbacter7 started w 8.2-8.3ish pH and zero nutrient, what should I be looking for in this cycle to indicate it’s completed? Loving my rockwork...

We all know there are tons of additives/treatments/supplements in this hobby... Some have proven their worth and others have been branded 'snake oil'... Using the poll tell us what bottles are considered 'essentials' in your fishroom (pick your top 4). If there's one that's not mentioned in the...

I know I will need to test before doing additives. I don't have a LFS nearby and want to get some supplies in advance. My tank has been cycling and I want to be ready as I stock my tank. What additives should I have on hand for fish, soft, sps, and lps reef tank? I obviously won't have all of...

So I have lived my life setting up tanks the old fashioned way by adding bacteria and waiting for the nitrate spike after a few weeks / months. However recently my parents set their saltwater tank up in less than a few days using “Nano start prodibio vials”. They have used live sand, rock and...

I have a reef tank that most likely has either brown diatoms or dinoflagellates growing on the gravel/sand. Tank is at least a year old. Tests indicate excellent water quality with the possible exception - API kit shows nitrate @ 0 & phosphate checker shows it @ 0.03 so maybe too low? meaning...

Does anyone know what is on my sand and rocks? It is covering some of my softie corals at the back of the tank. GSP, Zoas and a toadstool coral. Any ideas what it is?

My clownfish has had this crater looking thing on his face the past week. I’ve been treating it was a medication for bacteria infections but I’ve had no success. I’ve piggybacked this with several 25% water changes, no luck. Since this has started, my poor guy has gotten popping eye as well as...

So I bought some aragalive sand and it came today. Problem is that the bags broken and i was planning on storing it and using microbacter start xlm+ quikcycle. What do I do... Add it eventhough it might interfere with the microbacters or just wait for a refund..

ok so i decided to feed a little be more mysis shrimp today like double what i’m used to because my nutrients were low but then my tank is now going through a bacteria bloom could that be the cause because if it is then i’m lost for words and how do i fix this

I just had a friend of mine cycle some of my bio media bricks in his sump for a few weeks and had picked it up today. My question is if I can leave the bio-media in a container for a few days in the same saltwater it was cycled in. Will it require a heater or surface agitation? My reason...

So I’ve been reading about the potential dangers to caring for a reef tank and i have read about palytoxins and Mycobacterium marinum. These are things I will worry about because I am OCD and can’t help it. If anyone has advice on how to safely care for a tank without having to worry about these...
