diatom

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%...

Are these diatoms still or could they be something different, or are diatoms dying and reforming? I'm confused. I'm at about.the 1 month, 1 week mark since putting biospira and first fish in. Some of this algae is Dark brown, some very light brown. Some rust colored (a yellowish rust) like...

Hi everyone, this is just an update on my tank 4 weeks in. I still have nasty diatoms, started getting alot of green algae. And it doesn’t look like it’s going anywhere anytime soon lol. My nitrates and nitrates are 0, and i use rodi water so i’m a little confused as to why they’re still here. I...

I know this diatom is quite common in aquaculture, mainly for shrimps, but I can't seem to find any decent source for a culture for me to start from. In addition, places like AlgaeBarn blend them in with their phyto feeds they sell.... but thats clearly not pure.The most promising seems to be...

So I’ve had my first zoanthids for a week and I’ve had plug with 2 different kinds of zoas and I noticed that the first kind on the plug were and still doing fine but the different kind has been closed for awhile and I noticed some brown algae most likely diatom on the two polyps. I found it...

Photos, video, and parameters below. Finished Chemiclean treatment and followed instructions closely, which completely got rid of my cyano problem and sand was super clean immediately after. However, 1 week later, I'm noticing this algae that is ONLY on my sand getting worse. I know my nitrates...

Hey everyone, I have a pretty new tank setup. 100 gallon DT, 32 gallon sump. About 120ish total volume. I used cycled media from a previous tank to help get this one going, along with Dr Tims bacteria. It is about a month old. Here's my stock: 2 clowns, 1 royal gramma, 1 BTA, 1 Rock Nem, lps...

Hey guys! I’m a new reefer and I believe what I’m experiencing is Diatom algae which I’ve read that just letting it play its course is what I should do. I do have some green algae starting to grow and hopefully that will cancel out the Diatom (if that’s possible). I’m just looking for...

Salinity 1.026 Nitrate 0 Phosphate bounces from 0 to < .02 PH 8.2 Alk 10 Calcium 440 Mag 1500 I use RODI water, 0 TDS. Tank Age: 6 Months. So this stuff has been in my substrate for awhile now, it was brown, but now is green. Substrate gets plenty of flow. I've had to adjust it a few times to...

Hey guys, here is my very first saltwater tank. I’m very excited!!! I’ve wanted to start one for years now and I finally did. Any advice for a new reefer? Especially on how to deal with diatoms? I’m on week 4 now and it’s starting to explode!

Hello! I have a newly cycled 40 gallon FOWLR tank that has a pair of clownfish in it. I started noticing these little brownish/goldish tiny spots popping up on the live rock and aragonite. I am wondering if it is the beginning of a diatom bloom? Not sure what else it would be. If so, what should...

I just got this tank from a friend about a month and a half ago and the diatoms just went crazy about 3 weeks after setting it back up. The tank has been established for well over a year. I got 2 oscelarous clowns a cleaner shrimp and a small goby, 5 astreas snail 5 nasarious and a few other...

Dear users, Suddenly out of nowhere my aquarium is covered with brown stuff. Snails died, and corals - especially polyps such as greenstar (which has been very thriving before), and zoa are retracted and seems to be very stressed as it is all covered by that brown stuff. It can be dusted off in...

Hey everyone I’ve had my tank cycling for 2 months now and I’ve been pretty on top of cleaning my rock scape of algae and watching my Params. Today after work I noticed a ton of rusty colored algae plus some bubbles trapped into them is this diatoms or Dino’s and what should I do to solve this...

I have brown dust algae on glass that looks like a diatom bloom but also green and purpleish hair/slime algae on live rock as well as what looks to be sea lettuce. Any ideas?

Hello, I'm new to the site. New to the saltwater hobby as well. Tank is about 2 months old. Waterbox 70g (45g top and 25g sump). I have 8 fish (2 mochavinci clowns, 3 cardinals, a flameback angel, royal gramma, and a lawnmower blenny). All seems to be going well. They all like each other...

Hello R2R! I currently have a 13.5g fluval tank mixed reef that I want to keep as many different types of snails as possible for collecting purposes. Currently this is the only tank I can keep right now. My CURRENT livestock is as follows: 1 Exquisite Firefish 2 Porcelain Anemone Crab 2...

Hi All, I've got this reddish/brownish thing that keeps growing in my sand. I stir the sand almost daily, but the next day it's back on my sand bed. It almost looks like diatoms, but I'm not sure that's what it is. My tank is a little over a year old. At this point I'm thinking either dino or...

Hey everyone :) Bought this LPS from the store, they said it was a goniopora but i cant find any similar images googling goni species. can anyone ID it? also I may have added him to the tank too soon. He's lost some polyps and is pretty retracted, looking quite miserable. and he has a lot of...

Hello all! So I used to have a reef tank and had a very “text book” cycle, ammonia rises, then nitrite, then nitrate, then a big diatom bloom and a die off. This time around I had the same chemistry, but no diatoms, it went straight to a dusting of green algae. It’s been about two months and a...
