algae

Hi everyone! I've had this tank for close to a year now and recently this algae has popped up. I've undergone multiple water changes, but it keeps coming back. What is it and what can I do? Thank you so much!!

This morning i saw this green thingy on one of my plant, then i remove it by cutting the plant and take a closer look. I'm not sure if it's blue green algae (cyanobacteria) but i'm kinda pretty sure because it has a smell to it, it's like the kind of earthy smell. Right now i don't do...

Hi everyone. I have a Java fern plant in my aquarium and recently I noticed a few of the leaves have started to sprout these small root like sprouts. (Photos for clearer reference) upon researching online I have assumed the plant was producing new off shoots but these don't look quite like the...

I’ve only just started cycling my tank and today my partner noticed this white stuff on the wood in my tank. It looks like tiny jellyfish. Is there anything I need to do about this? I’ve been advised not to change the water until I’m done cycling. It was VERY green in there yesterday, looks...

I just clean the tank yesterday and this white dot appears all over in the tank. Is it just the algae or it’s something like germs or bacteria that are bad to fish? thank you.

I have been fighting to figure out what this black stuff on my Anubias is. I presume its algae, but i have 0 phosphate, Nitrate, nitrite, & ammonia. The canister filter has been cleaned and replaced with fresh media. Not Pictured: I have 8 Otoc Cats and a few Amano Shrimp that wont eat this...

What could this be on the glass of my tank? First time it has appeared. It doesn't move it anything. Is it just algae?

Hi Everyone I'm looking to build my empty nano (21 litre/5 gallon) into a potential shrimp tank. I'm looking to set up something simple so I can work on some core skills in the fish keeping world. I took a look at my local water provider and the stats they have on the water in my area. The...

Due to my disability I rarely do water changes but pay a good friend to do them for me. She's awesome. But she is out sick with a bad pulled tooth and 5 stiches so I have to start some of my water changes myself (it takes me about 4 hours - she can do it in 1 1/2 hours). We typically do a...

I just tested my parameters about 10 minutes ago so I know they’re pretty accurate. pH: 8.4 (tap is nearly 9.0) Ammonia: 0ppm Nitrite: 0ppm Nitrate: 5ppm It is a 20 gallon high with 6 corys, 2 adult Gardneri killifish, and a couple Gardneri fry. Relatively under stocked I think, but fully...

Hi Everyone! I'm pretty new to the forum - I posted once before to ask for help on my 21 Litre Nano, because every time I did a water change, my nitrites would go up! I've actually had to break down the tank and nearly gave up on it (and the hobby) altogether - but here I am. I started having...

Hi guys, Back again with probably yet another rookie problem. I saw some algae growing in my tank a week or 2 ago. Figured it was because I didn't have any algae eaters in the tank so I added some oto's to combat the algae. Fast forward to today and my oto's aren't actually eating the algae...

Sorry this is so poorly written but we're doing a water change later today and would like at least a couple comments: The first example is 'TANK A" the second example is 'TANK B" both taken today about 4 hours after feeding - the debris you see on the ground in both tanks is mostly empty snail...

So I was having some trouble in my 10 gallon with this algae, but I moved and then transferred the fish and plants to a new 20 high. The 10 now has a betta and snails. Anyway, on my amazon swords and a little bit on my cabomba and rotala indica, there’s this fuzzy algae. Diatoms? What do y’all...

Good day. I have this brown stuff- algae? Debris? on most of my plants and inside my canister filter and tubing. Help! What is it and what can I do about it? I have .... 20 gallon long tank with penn plax 500 canister filter with foam and sponge filter media. this week added fluval prefilter...

10 gallon cycled tank with 3 Gardneri killifish, 6 corys, and 2 nerite snails. Cycled, 0/0/15. It is only on my amazon sword plants. I’ve not noticed it until I moved today and had to completely redo my tank! what do you think? I have algaefix chemicals but that’s a last resort.

I had a bit of an algae problem recently, bright green growths on the glass, with greenish water. I've managed to settle that problem by reducing the amount of light in the tank. I haven't been able to get the growths on the plants under control. I've cut back/trimmed most of the plant due to...

Hi Friends I'm new to the forum, and excuse me please for skipping out on the introduction, but I've got a bit of an urgent problem I really need some help with. If you could read through and give me some advice, I'd truly appreciate it. First, I'll cut to the facts of my set-up: Tank - 21...

So I’ve had my 40 gallon tank set up for about a month or two now. All the rocks and decorations were in my previous 20 gallon tank (besides one new one). I only have one goldfish in the tank at the moment. I recently removed all the gravel and ornaments to treat anchor worm for 2 weeks. I...

Hi, I’m still pretty new to the aquarium hobby. I have a 70L (18 gallon) tank that’s been running for 4 weeks. I was a told by my local fish store to do a fish in cycle (a mistake I have since found out) so I am currently nearing the end of that (I think). Recently there has been a load of...

My Cyanobacteria is somewhere between under control and out of control. After following advice from here including reducing nutrition, adjusting light, tweaking the plants and following a rigorous water change schedule that lead to massive die off of my creatures and plants, I am still having...

My tank has a serious algae problem. The only place to put my betta tank was by a window, and now there is a constant film of algae covering everything. Now, I wanted to add a nerite snail to the tank to help eat some of the algae, but, after moving around for a day, he stopped moving and died...

Hey everyone. I'm having an issue with my fish tank.. I recently noticed a white cloudy/fuzzy layer forming at the top of my tank water, on the surface and on the glass. It doesn't seem to be attached to any decor, mostly just the glass and water surface. I've actually been able to scoop it out...

Hello everybody, I have algae problems in two of my aquaria. I have blackbeard algae in my community tank, and cyanobacteria in my blackwater aquarium. The blackbeard algae has gotten completely out of control and is everywhere. The cyanobacteria is contained to lower parts in the substrate and...

I found this in tank this morning, is it dangerous? Can I let pleco eat them?

Ever since I put a rock (I forget what kind) into my Betta's aquarium, I've started having trouble with a grassy moss-like-algae. I'll include pictures of it but not only is it covering the rock but it's gone everywhere including coating all of the plants and the substrate in a weird gritty...

Ok, so I was cleaning my betta fish's tank and doing a water change when I noticed his rocks were slimy almost. Curious i rubbed the rock and all this green particles came up. Is this Algae? Is this good or bad for his tank? His tank is not over run by it. He is is a 5.5 gallon tank, water temp...

a small amount of white fuzzy looking algae has started to accumulate on some of my plants and around the intake of the filter. I recently re-aranged the plants and rocks to better suite the fish and I’m just wondering if this might be the cause, any help is appreciated

Hello everyone. My new 10 gallon divided low tech tank has been running about a week now. As the light was so poor on the hood I’ve put a tabletop led grow light shining into the sides. My plants look great, my weeping moss divider is filling out amazingly well with the directional grow lamps...

Hello all. Brand new here. I have a 20 gallon tank. Last night or of nowhere the beta fish we had developed very bad fin rot on his tail and he had white specs on him. The tetras we have also had white specs. Fearing the worst I assumed it was ich. Went to get ich medication from pet smart as...

This is from my 20long with penguin75 filter and 30”lifeguard full spectrum led light.

I just got 2 Marimo moss balls because they r beautiful & low maintenance live plants. I have no other live plants in my tank so I'm hoping these work out. Currently they r washed & put in a jar for a couple weeks because I'm paranoid to put them in my tank with my fish. I was wondering if...

Could it be a bacteria bloom / algae bloom? How can I tell the difference? This is in a 10 gallon tank. Not sure if this is a result of a water change (I do 15% every week) and a few weeks ago I had to replace the filter cartridge. Is that the reason why there is a bloom in the first place...

Hello all, Not sure if this is the right section to post this in but here we go, I have an African Cichlidé tank and my goal was to grow algae green on my rocks. Nows I am dosing Seachem flourish and Seachem phosphorus and have a power glo 18,000k t8. I took some rocks from my garden as I...

Hello! I have a common pleco in a 29 gal (along with just 1 female Betta because I have a sorority but she was too aggressive for everyone else but she's been good with Tom the plecosTOMus) anyway, recently Tom has been acting really odd. At times he will be super still, not even sucking on...

I have a 55 gallon freshwater planted aquarium in my high school classroom. We added a heater last week because the tank was getting too cold with the hvac being set to turn off when school is not in session. I guess one of us bumped the timer on the lights b/c the lights were on all day...

Hello, I've had a my tank since May of 2019 and everything was going great. Recently though (about a weeks ago) I noticed that there was some light green, spots of algea growing on the glass of my tank. It's there anyway to get rid of it? I've tried using an aquarium sponge to remove it but the...
