diatom

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...

Hey everyone, I know this is a noobish question, but an answer would help heaps. Regarding my 240L Aquarium with a top filter (spray bar), running activated carbon (now expired), heater, 2 Aquael pumps each 2500L/hr. The tank is about 6 weeks old, has about 21kg of live rock, two Ocellaris...

Hello, I'M new to the forum but have been in the hobby for some time before quitting and coming back. I started a 20g IM nuvo over a year ago and have been battling with Brown Diatom Hair Algae. When I set up the tank I had (and still have) a skimmer, bio-pellet reactor, cheatomorpha carbon and...

I've faced this before and quite honestly didn't exactly pin down the problem. Basically I am getting a brown diatom on my sandbed and it's actually becoming somewhat solid in places. Alk=8.0, Cal=420, and Mag=usually at 1350. I don't overfeed (feed the fish not the tank) but I do feed corals...

I've been doing my cycle for a week or 2, a had a diatom bloom while back. I used LR etc. and live bacteria added to water. However, I noticed my Nitrite AND nitrate levels are rising at the same time. Is that normal? my LR ratio is 80% Live 20% dead I have some green algae growing few days...

I have a 75Gallon Almost 2 year old , I have GFO and CARBON running on my system. the light I'm using is T5 light bulb , they're approximate 8month old I leave my light on from 12Pm to 7Pm, I also do weekly water changer on TUESDAY. So I hear about the vinegar dosing, I don't really know much...

Day 17 of cycle. Tank has a lot of brown algae which I know is supposed to happen. I think I just need to hear it from someone other than the voice in my head. LOL Also, I've read so many differing opinions on cleaner crews I'd love to get y'alls opinion on how many, types and when to add...
