algae

Hi averyone, So i had a ball of chaeto in my main tank for few moths, but it died due, i think, to the lack of light with coral growth, so i wanted to add a little "refugium" in my Max Nano (and i had my 1st nutrient spike because of the chaeto dying, i think) so i bought a Tunze Eco Chic and...

Hey all! So my tank has only recently been set up, it’s about a month and a half old. I used live rock that was being baked in a bucket for about 4 months prior to setting up, it only was ghost fed, no corals or anything on it, closed system. I’ve recently had this green slime algae pop up...

Hello! I have this weird brown algae growing on some of my corals. It looks like it could either be dinos or brown hair algae but it only grows on a few of my corals plugs and only a couple spots on my rockwork. The tank is about 5 months old. I run a protein skimmer just did a 20% water change...

Hello everyone! About a week ago I purchased a Zoa frag. And I have noticed it’s more or less encrusting around the frag unlike the normal Zoas that I have seen and purchased. The picture will be posted below. But since putting it in the tank it seems to have some sort of algae hairs growing...

So rn im having a huge problem with hair algae and Dino it is everywhere. I ran hydrogen peroxide for a today and now was told just to take it all out and buy pods so i bought pods and now we’re waiting. Had to take out peroxide bc it was hurting my corals. Does anyone have any other ways in the...

Hello everyone, I have a 7 month tank with which I always had an issue keeping my nutrients at a normal level, they were always low. About 2 weeks ago I started noticing what I believe was a type of algae I have not had before. Its ridgid and it really attached itself to the rock and now it...

So I got an algae problem and it slowly starting to spread faster. We’re thinking adding more filtration will work to compete against it. Like a skimmer, cheato, etc. What’s everyone thoughts on this? Sorry for the picture it hard to get a good picture.

I found this thing on live rock that I bought and I can't find what it could be. First, it kinda looked like regular red coralline algae but now it seems like some kind of macroalgae. It grows attached to the rock. Any idea what it is? Could it be harmful to the tank? Can I help it reproduce...

I changed my lights a week ago to a much better light and there are microbubbles and algae I think growing on the sand. Is this normal?

Hi all, I’m 3 weeks into cycling my tank. After week 1 I got zero ammonia, however, nitrite keeps getting higher even after doing 75% water changes. Yesterday, I noticed there are white spots on the heater holder, also, there are floating white stuff in the water column. This is how it looks...

Does anyone know what algae this is? It’s covering my top half of my rock. I’m thinking diatoms but not sure.

They seem to be pretty and harmless, I wonder if they are categorized as macro or not? How fast will they grow/reproduce and how large can they become? Thanks in advance!

Hey there, So we just got an algae for our refigum, but didn’t jolt down the name. We searched online to see if we could find it. However, we are having a hard time identifying it. Does anyone know what it is?

Hi. I have a Fluval Flex 123L which has been running for about 1 year now. I have always had a major green hair algae problem which I just put down to the fact the tank was new and going through the motions. I work offshore so I'm only able to do a water change once a month which is a 25%...

QUESTION: best way to get the HA in the sand bed? My siphon doesn’t seem to pick it up since it’s stuck itself to clumps of sand How it started: So back in December, I left my RODI unit outside and it froze and broke a canister. Took me over a month to fix that so I had not been doing water...

I have an algae appear that I need help w ID. It grows in a stringy reddish brown growth pattern. Also it may or may not have air bubbles within the algae . It may be clinging to it from my HOB SKIMMER. My tank is 2 years old. Thx

Using the movement of this beautiful algae I’m working on landscaping , Does this flow look good? It’ll be a softie & LPS tank. I was finally able to do some deep maintenance after some procrastination (and replacing my RODI canister) and I decided to swap out a smaller power head I had in this...

So a buddy of mine started a reef tank with fish after seeing mine for a while. They made a mistake and somehow something toxic got into the water. He gave me the dying stuff to see if I could save it. Most of the stuff was too far gone and everything died. I kept the corals incase they may be...

So I have a tank that's about 2 and I don't have any coralline algae, despite seeing good growth and healthy coral. At first I thought it was because I had a bunch of urchins but they were rehomed due to a lack of food and in the year they've been gone I still have none. I noticed patches that...

Title says it all. I've been in the fish game on and off for about 30 years now. I don't think my morale has ever been this low. I feel like my tanks are just becoming a source of stress in my life. My 20g reef (below) has been up since 2019, my FOWLR has been up since 2015, and I also...

I’ve had trouble keeping some snails alive for very long. Cerith and Nassarius seem to survive long term, however Astrea, Trochus, and Turbos seem to not do well. There is PLENTY of algae to eat. I suspect ingesting Dino toxins may be the cause, but I’d value a second opinion before I buy a...

Hello everybody, I have had my reefer 425xl running about a year now and my corals and fish are thriving. here are my parameters which remain stable: salinty - 1.026 KH - 9 Ca - 450 Mg -1280 Ph- 8.2 Ammonia - 0 Nitrate - 2 Phosphate - 0 I have an annoying algae issue which I believe is Dinos...

Scrubber was used only for a few months on my frag tank before I took it down for house construction work. Price is 300 firm. Pickup in North New Jersey. Shipping is available (not included in price).

What’s up everybody, just have a quick question. I am battling some sort of algae on my sand bed and have been for a couple of weeks now. They are like thousands of little individual balls of green algae, and I can’t find anywhere on what they might be. There is a ton of them and I do not know...
