algae

My first take is literally just algae, taking over the tissue. It’s still spreading like wildfire so not so much concerned just curious for knowledge.

Hi, recently I noticed some black stuff started growing on my rock. The thanks is around 6 months old. Should I worry? It’s pretty hard to the touch but feels more “slippery” than coralline.

I've got some algae starting on a few rocks. I purchased Sea Lettuce macro algae 8 weeks ago from Algae Barn, so I'm wondering if that stuff has the ability to frag and grow elsewhere on its own readily, or if this newly emerged stuff is perhaps a green shade of Dictyota. Do I keep it in place...

Hi all, I have a 75 gal with sump. Lots of macro in sump and some in main display. Tank is 120 days old. Went through the high ammonia phase, went through the high nitrates phase, the Dino bloom, then into the bright green algae phase. I feel like I should start to see the bright green about to...

Hi. I’ve been dealing with this for a very long time now with diatoms growing on my sand and I’ve even reduced lighting a lot and they still keep coming. Now I just decided to ask if anyone knew what was growing on my rocks and how I can get rid of them and maybe grow some corraline algae. I’m...

On my zoanthid very frequently I’ve had these bubble things appearing on my zoanthids. I’m taking them out and popped them and put the Zoas back in the tank. All they do is pop up and I’m not entirely sure what all of this is. I also cannot get my zoanthids to grow anywhere on my rocks. I’ve had...

This started growing in my refugium and has started taking over the entire fuge. It puts down roots that are attaching to all of the live rock and bio balls. Can someone help identify? Is it a good algae or nuisance/threat? Thx!

We have chaeto back in stock until it runs out. $15 for a good baseball size ball plus $5 shipping. $20 shipped.

Having a nightmare with the algae on the back wall. The rocks are cured that way and I’m not particularly bothered about them (I read that they should turn darker and purple as coralline takes over) This algae is so hard to scrape away, I press as hard as possible with my scraper but it just...

I'm selling some of my String of Pearls algae again! So, if you're interested let me know by sending a PM! If you're still thinking about it but are unsure and have some questions, feel free to post in the discussion section of the ad. Any orders placed during the week will be shipped the...

Hi all, I have had this algae in my reef for a few months now. I believe it’s mostly turf algae though some appears to be stringy like hair algae. It’s very difficult to remove from the rocks like turf algae. I have been treating with microbacter clean daily for probably about 8 weeks now but...

hello, I ordered some algae and it will come in two days. I don't have a refugium, so I am wondering if I could grow algae in the sump without using the reservoir... I have a heater, lights, 2 return pumps, 1 skimmer and 1 reef mat in the sump

Hey all! Upon starting my Waterbox 20 journey into reefkeeping, I purchased these turbo snails at my LFS. They were coloured brown, and inexperience made me not question it. I didn't know about peroxiding snail shells, and added them. Turns out they were covered in lobophora algae. After...

Hi guys, I'm starting my first tank. I got my tank, dry rock, live rock, live sand, heater, power head, filter. And I was planning on getting a clown fish and adding API quick start to start my cycle. However I got busy and put it off for about 2 months, not really thinking that it would cause...

I'm thinking about sealing the top halves of all the dry rock by soaking them with liquid super glue. I got the idea from another discussion on here and confirming similar observed results with another reefer. In my 250 rebuild, the connections where I heavily glued together and are under high...

I have 2 month old 35 gallon tank with 5 fishes and 2 corals. Nitrate is around 2. Haven't checked phosphates. Started noticing this greenish brown algae on my rocks. I am guessing it is the "Ugly phase" of my tank. I am treating the tank with a daily dose of Brightwell Aquatics Clean and Bio...

Hi everyone, I am new to the reef2reef forum and also reef tank. Recently I bought a maxima clam. But sooner or later, I found the phosphate level is too high (>2ppm), which kills the Duncan and hammer coral inside. I used phosphate removal to reduce the phosphate down to 0.25. My clam still...

So I'm currently fighting off detritus or diatoms. My lfs guy said diatoms. I can't really tell the difference as I'm pretty new to the hobby My current livestock (not cuc) 2 clownfish (one percula one ocellaris) 1 neon blue goby 3 blue sapphire damselfish (probably one, haven't seen the other...

To start off with what I know, I have been working with reef tanks for many years and freshwater tanks for much longer. My knowledge on the cycle is pretty good, but my reef tanks were never great, and now I want to change that. I am starting out with dry sand and dry rock which is very...

Newbie here. I have a Fluval 13.5. The tank is 7 months old, using ro/di. I went through an ugly phase and thought I was done with it, but now have something growing as you can see in the pics below. After the lights are on for a while, air bubbles show up. Mostly growing on substrate and walls...

Thank you everyone for your interest! We have enough takers for this batch and the next. Please message me if you would like to be added to a wait list since we need to harvest this macro every 3-4 weeks. Thank you! Gracilaria curtissae I’ve had this macro in my tank for a year and it readily...

Hi, Hi, i’m currently batteling dinos and I was wondering if you could help me id these. Zoom is 250x. My guess is amphidinium small cell.

Found the clearest jar I could. Placed in a piece of loose rock. Disassembled a USB LED. Soldered some spare wiring to the LED board while it is fixed in position to the lid ~ This step was quite intricate and the new circuit should be wrapped in thread tape/electrical tape and protected from...

Hello, I've been battling this algae for a couple months now and I can't get rid of it... I can really use some help, quitting this awesome hobby has crossed my mind.. It's a very slimy fuzzy looking brown algae/bacteria. I've tried sucking it of, which reduces it a lot but only the top layer...
