algae

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...

Hello, I’ve had my tank up and running since the end of August. Around October I started seeing what I thought was diatoms. They started slow then exploded and covered my rocks and sand. The trochus snails are eating it which is making me believe it’s diatoms but at this point I would think they...

I have a 16 gallon biocube with some snails that don't eat a lot of algae, zoanthids and a blastomussa coral, and a citron goby. My question is, I have a lot of algae growth on my sand bed and it looks like I am getting some hair algae on my rocks. I just got the corals yesterday. If I were to...

Hello, I've went fallow on my tank for a couple months due to a velvet outbreak. During this time I started to get some GHA throughout the tank and it slowly turned into this webby reddish algae. I was thinking about getting some fish soon since the velvet is more than eradicated by now, but I...

Yes I know. GHA outbreak after the hurricane. Been battling it pretty well I think. Turned on whites to get better pics. it is a spongy red brown algae forming in balls before it spreads. It was only on the frag plugs of two Zoas, completely took them over. After a peroxide bath and a bit of...

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...

Hi all. I am having issues with my zoas. I noticed that they have started to not open up, some areas are disappearing and I am noticing a some are kinda turning black and disappearing. Can anyone hell. I have them in a relatively low flow and parameters seem good. Nitrates maybe a lil low since...

Hi All! Hoping to get some help with an algae ID. The pictures aren’t great but I have these small maroon dots that have shown up. I’ve dealt with Cyano before and though this is a similar color I don’t believe that’s what this is. While this new algae was in the tank I had a patch or two of...

These are sturdy, slow-growing sprouts that kind of look like leeks. What are these strange sprouts? Thanks for any help.
