algae

Hi all, I have this algae here and I got an urchin and 6 trochus snails to deal with it but they won't touch it. I had the urchin first and he ate some but then stopped. I got the snails and one of them had hair algae on it. The urchin destroyed the hair algae on his shell but still won't...

Hi all! I recently had a massive GHA or BHA? that I´m trying to control. But I noticed a neon algae between the Hair algae. I don´t believe its coraline since it seems hair-y like. Any ideas on what type of algae this could be?. My tank is a 15 gal running for 4 months now. Corals seem doing...

Hello, please excuse my English, it's not my native language. I'm seeking your help to obtain advice on improving my fight against derbesia, also known as GHA (Green Hair Algae) in English. Currently, my aquarium is equipped with a DSB (Deep Sand Bed) without a sump or skimmer, and I'm facing...

Hi everyone, hoping not to annoy asking this as I’ve seen similar posts. My tank is roughly 2 months old so very new and I am learning every day about the cycling and thank this group for so much info. Is this good ‘algae’ or should I be doing something different? My levels are great: KH -...

I tried manually picking off, buts it’s hard to get then used reef flux. But it didn’t work. Please help.

Need help not only identifying what kind of algae this is but also ways to help prevent and get rid of it. This tank is the Evo 13.5 with stock everything. I have added the FluvalSea Mini Protein Skimmer. Sand is Caribsea Fiji Pink. All of the levels in the tank look normal and the salt level is...

Looking for some help/advice with my mixed reef tank. Over the last month and a half I have been struggling with diatoms and cyano outbreaks, and the one I’m currently in right now is not getting better. This tank is exactly 1 year old and this is the first issue it’s having. Over the last year...

Hello all, I have a 10g fairly new tank. Worry not everything is cycled of course but I started noticing orange patches here and there on my sand. All levels are within normal ranges so I have no idea what this might be, but then again I still consider myself a beginner and I don’t know much...

I used it recently to help fight back against cyano, and I see it being used quite often to help with algae. How does it work? Why does it kill the bad stuff, but the tank seems to be perfectly fine? Why is the good bacteria spared? How is it affecting the inverts? Does it accumulate and need...

Hello I am running a Fluval 60. Have gone through green hair , then red Cyanobacteria and now have this lighter green covering that looks like the red cyno in terms of coverage on the sand bed. Tank is 6 months in with a couple of clownfish , snails and a shrimp. No corals currently. Stock...

Back in February I had a huge takeover of cyano, bryopsis and GHA. First photo, I know it was bad. I was in a bad headspace I know what happened: overfeeding, lack of maintenance & topping off with questionable store bought water and the occasional tap water top off. I’ve manually removed...

So I started my 55 gal tank up in the beginning of the month, and I’ve been posting updates every now and then. This is my third attempt at starting a saltwater tank, and so far I haven’t had any catastrophes yet. I just did another weekly 4 gallon water change, and all of the brown algae is...

Does anybody know what type of algae this is? And is it bad for tank?

My tank is starting to get over run by algae, I know there’s a lot of chemicals and additives to rid algae growth but what is a very quick for sure way to rid algae from corals Skelton, between polyps??? I’m dealing with very annoying hair algae no matter what I do I’m thinking turning off...

Hey, I know they aren’t the best pics but wondering if this is bryopsis. Just removed a rock that def had a quarter sized growth on it so wondering if this is it too. Hard to tell for me. One other frag has something similar.

I bought a sea sponge a few months ago. It was doing great for weeks, then fell over between some rocks for a few days. When I pulled it out of rocks, it has some white and brown goo on it. It looks like algae of some sort. I can see the orange flesh beneath, but the goo seems to be spreading. I...

Went away for a week and came home to this completely taking over my sump. Protein skimmer working very hard. Used up half my reef mat in 3 days. It feels very slimy and comes apart quite easily. The consistency almost feels like slime around a piece of string, but the second you touch it, it...

I just came back from a week long vacation and found this stuff has completely taken over my sump. Any idea what it is and how to get rid of it?

Hello! Rather new to the hobby here but my tank has been running for just over 6 months. I’ve had coral for almost 3 months. Went through a few different ugly stages already. I thought things were finally calming down where everything was clean again for almost a month and everyone has been...

So i have a 33 gallon long tank that is about 2.5 years old and I have never been able to defeat algae. The tank is overrun with bubble algae and GHA. I'm even dosing Vibrant (algaecide) but nothing seems to be working. Almost every week I have to clean pumps because they get clogged up with...

So I am starting up a new 22 gallon tank and planning on bringing my clowns and inverts over from my Fluval 13.5. Problem is the 13.5 has been showing signs of slight dinos from a rock that I had recently added to the tank after buying some anemones. I would love to move the anemones to the new...

The algae is green, i wonder if it's some caulerpa. I had some racemosa at the beginning but killed it (it bleached probably because of the lack of nutriments). Could you help me to identify this one?

Algae problem causes me to suffer after past 6 months and finally found out is my light is too long after chit chatting with in a fish shop. Anyway, recently the tank suddenly appeared many kinds of hitchhikers: a kind of algae,Vermetid Snail, one or two fireworms (At least looks like, it has...

I can't find any other algae that looks remotely similar. Has anyone ever seen algae like this? It grows in long vine like strands along the rock and has spread across all my rocks. Easy enough to remove with tweezers but can never remove all of it. Thanks.

@Randy Holmes-Farley Hello. I have a bryopsis and gha problem in my 150g dt and sump combined aquarium. I have tried manually scrubbing it off the aquascape however they keep coming back and now have taken over almost all the walls and rock. I have been reading. Lot about Fluconazole lately. I...
