diatom

For the last few weeks I’ve been reliving my annoying battle with diatoms and hair algae. Used to have a big issue with it in my 10 gallon even though it was about 7 months old and now it’s started up again in my new 30 though it’s a bit less intense. 30 gal has now been running for 2 months...

Hey sorry if this has been discussed before, but this has been popping up around my tank and causing me to panic. I can’t tell if they’re dinos or diatoms. Will it kill my corals and should I add a clean up crew to my tank? The tank is a little over a month old with currently no fish and this...

Hello everyone, I have a 30 gallon tank and it is a few months old now. I have one shrimp and one clown in there for now. I did not want to over do it starting off being this is my first salt water tank. Water was clear until this past Friday when I did a water change. I have been having...

Hello reefers! I am new to this hobby. My tank is around four months old. I am facing this brown algae situation where the algae blooms at day and disappears at night. This situation arise from the beginning of this month. I am not sure if its diatom or dino. Please note that My nitrates were...

I’m thinking this is just green hair algae and some diatoms, but just figured I’d check with some people who are more experienced. I also have hydroids which appeared two days ago. Any concern with them? I was told they would go away on their own?

Hey everyone, I am in need of some help here. I have been battling, what I believe to be, diatoms for close to three months now. I have recently checked my silicate level which was close to zero. I could not say exactly as it was a Salifert color comparing test. You understand these are not...

I have a pocket microscope Carson 250x. I made a videos of one sample of hair algae on different background. Can anyone identify which dinos are in the video? It all started when I had the stupidity to clean too much stone in the aquarium from algae with peroxide and vinegar and upset the...

Hi all, first post here, and relatively new to the hobby as well. My tank (25G) is a very, very new tank, being about a month old. My current Parameters are as follows: Salinity: 1.025 Temp: 27 - 29 degrees celcius over course of day Ammonia: 0.15 Nitrates: 0.25 - 0.5 Phos: 0.1 - 0.25 Mg...

Hello community, I am new to this hobby I have setup my tank 6 weeks before. After week 4 I introduced clowns and purple dottyback. Purple dottyback disappeared 4 days ago in my tank and from that day onwards diatoms start to appear and its growing quickly. I have waterbox marine...

Hello Fellow Reefers! I setup this tank about 4 months ago. I used all dry rock and dry sand. I went through the ammonia cycle within the first month. Since then I have been battling what I believe to be Diatoms, I am unsure what it is for sure. I knew i'd hit the ugly stage but this blew me out...

So, no matter what I do, I keep having this reddish/brown coating come back again and again. The system itself has been up and running for 16 months, and I transferred it from a 60-gallon tank to a WaterBox Marine X 110.4 in August of this year. I've tried vacuuming the film off of the sand...

For reference I’ve had my tank set up and going since august 20th. I noticed the diatoms about 3 weeks ago and as of Sunday cleared off the rocks almost completely. Now we’re right back to where I was before, just 3 days later. I have provided pictures of the tank when the rock was cleared on...

Hey guys! Well my 310gal has been up and running now since the Saturday of Labor Day weekend. I’ve had lights on it now for a couple of weeks. Just put my permanent light setup(coral cares) on it last weekend and have them on a 10 hour light schedule at only 20% intensity right now. I used...

So I'm currently fighting off detritus or diatoms. My lfs guy said diatoms. I can't really tell the difference as I'm pretty new to the hobby My current livestock (not cuc) 2 clownfish (one percula one ocellaris) 1 neon blue goby 3 blue sapphire damselfish (probably one, haven't seen the other...

I have been struggling to get my Nitrates above 0.00 for months. Even with tripling feeding to 100 small pellets and about 1.5 cubes of frozen a day in my 65, it hasn't budged. I previously used a Red sea test kei, but now use the Hanna HR nitrate and ULR phosphate and same results. 65 gallon...

Before this one i had diatoms (they’re not 100% cleared out but are practically only on the glass, before they were everywhere) Now this green algae is everywhere and it’s quite ugly. My tank is about 4 months old.

Hi all, hopefully you can help me!! I have a 24 gallon AIO waterbox peninsula, roughly 8 months old. I have been battling algae for the last 4-5 months. I believe its a combination of diatom, dinos and maybe cyano? the algae doesn’t completely disappear at night, but does reduce slightly. If...

Pictures are at the bottom will help with the context so yesterday morning all my coral were doing fine i was letting the week ride without dosing to see how much Calcium and Alk my tank would use. I tested my alk at around 2 Pm and it was low at 6.8 Dkh all my other parameters were pretty much...

This is my first saltwater tank and has been set up for 3 months now. It is a red sea 625xxl This problem started out looking like dino or diatoms. More brown in color with tentacle like balls of gas. I put an mp40 in the tank and the balls of air went away but the color turned more red and...

Hi folks, New to R2R and learning a lot from you guys. Thanks a lot. Started my cycle 4 days ago and spotted these orange spots on the sand tonight. Can you guys confirm those are diatoms? If I understand well its a good sign so I would be happy about it, just need an expert eye. The orange...

Currently have a 125g tank that was previously running at former owners home for 2+ years. Basically just transferred the entire tank to my house (minus the water). Two weeks ago, nitrates were sky high (150ppm). I dosed the tank with seachem prime because that’s all I had on hand. I did a 75%...
