algae

Hi everyone, So I’ve had this reef tank setup for slightly over 6 months; I had everything transferred in from my old tank 6 months ago, and for some reason I’ve had wave after wave of this algae come in. It’s a think jelly-like substance that’s formed on the rocks and sand bed. They don’t...

Hey guys, I just switched from a a80 tuna blue to an AI hydra 32hd. I know its overkill for a 20gal aio but figured it would be good as i plan to upgrade in the future. Besides the point the kessil was running at 100% i now have the hydra down to 30%. I have ran it at 75-80% for 1 day and corals...

Please help in identifying my algae. The photos are not the best, but it’s a dark brown almost mat like algae with the occasional bubble. Tank is a year old. Nitrates: 10-20 Phosphates: 0.25 Salinity: 1.026 Temp: 79 Thanks for the help!

Hello everyone, I am hoping to get some help with my Dino issue in my 38 gallon AIO reef tank. It has been about 2 month of having them and about 3 weeks of treating them. So far I have been dosing microbacter 7, microbacter clean, and phyto. Thus far I really do not see any difference in the...

Hello I have the RAIN 4 pole mount waterfall algae scrubber for sale. The pole mount is used, however the DOM and the gem lights (7 in total) are brand new. Asking for $500 shipped.

Hey all, I’ve been facing some cyano recently, seems pretty persistent and grows on my sand and rock. I just finished a flux treatment, and it started to appear in the end of my week 3 of treatment. It doesn’t hold any oxygen bubbles like Dino’s seems to typically, just grows over sand and rock...

We just got back from 10 days away to find this weird, thick white substance in our sump (pics below). It's pure white, thick and is mostly on the display drain tube, and on the bottom of the refugium. There is some in the crevices of the live rock that in the refugium too. It blows off in...

Hi hopefully someone can identify this for me. I’ve never seen anything like this before. I tried to manually remove it but it’s surprisingly VERY hard to scrape off even with a toothbrush. It’s a 6month old system 125 gal with a VERY LIGHT bio load(two clowns, a gramma, softies and hammers)...

Putting together a new system and decided on an algae reactor for nutrient export. Problem is my n24 is likely Overkill for what I'm working with.

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.
