algae

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...

Currently about to clean my tank completely to tear it down and set it back up after losing a battle with GHA and lobophora algae, that’s now in my equipment. What are the best ways to completely clean and sterilise my equipment so there’s no risk of transferring any algae spores or other...

Attached are images of the pest algae, which I’ve been dealing with for longer than I would have liked. It is comprised of singular stalks, which are filled with fluid (similar to bubble algae) and pop when broken. Any thoughts on ID? As far as treatment, I have upgraded flow and filtration and...

I have a reefer 250 v1 with a Red Sea reefer 300 protein skimmer that in my opinion sucks .. I was debating on removing it for an algae scrubber then I was wondering about removing it and just throwing a light and some macro algae there instead.it would save me some cash but would it be...

Hello everyone I have begun to experience algae in my first saltwater tank and was looking for advice for the next move I was thinking getting a conch since the one I had just died (not sure why) and also is there any sort of filter that could remove/reduce nitrates. Any advice would be greatly...

I think it's kinda neat/pretty and would like to nurture it into my new 70G setup; but want to make sure it's a friend not foe. This is growing out from a plate coral frag plug. It's light pink.

I come from freshwater fishkeeping. And always wanted to give coral reef tanks a try. I read guides and watch videos on how to set up a reef tank. Every coral purchased with research done before hand for best results. I started with corals that are listed as easy to keep. Mainly soft corals. For...

Hi there, have had slightly cloudy water and took a sample to find this guy. Not sure what type of algae this is. It has at least 2 Flagella, and is present when the lights are on. No sign of slime. Moves quickly as well. If anyone has any idea what genus this belongs to, that’d be great! Oil...

hey all, ive had some red/brown spots showing up on my sand, lately its gotten a little worse and I don't really feed a whole lot. I got a test done at my lfs last week and everything was zero, (except nitrate which was like 5ppm or w.e) which can obviously be a problem. ive started to feed on a...

Don't have much expectations asking this question, but when it comes to bubble algae, how do they grow? To give an example to my question: A couple days ago I found a fairly small shell covered in bubble algae. I removed it very carefully from my tank and looked around. I didn't see the algae...

The first thing you should do is slightly open the lid of the jar that the macroalgae is in. The reason for this is to adjust the pH levels slowly. With the lid slightly open, the carbon dioxide levels and oxygen levels will become normal, and the pH will gradually rise. Next, acclimate the...

Sorry for the bad pictures. It’s i. My fluval 13.5 and I didn’t scrape off the back side of it. You can kind of see it but they look like white webs all over the chamber in the back. Looks as if they’re keeping the chamber clean of detritus in the first one but the second chamber is a little...

Hi all, I have a 3x2x20” reef that has some persistent turf algae. I have a one spot foxface that occasionally eats some but not enough to make a dent. Other current fish include 2 clowns, a melanaurus wrasse, a flame hawk, and 5 small chromis. My nutrients are very low now, with nitrates...

Hi all Relatively new (couple of months) to the hobby and very new to this forum. I’ve been running my tank for a couple of months and have probably been dealing with all the things a new tank faces. I currently have a Fluval Evo and have got it to a place where, with a few fish and...

Hey everyone, I have been battling this stubborn algae in my tank for the past two years, and I want to finish it. I haven't been consistent with my treatments, which is probably why most of it is still here. Catch up on the progress from the previous thread about it...

I've had a nano tank running for about a year. I've had success with keeping most coral alive and some that are growing. Can anyone identify the formation growing on my top rock? I can't tell if it's an algae that has hardened or not. It looks cool, like a coral formation with "branches", but it...
