algae

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...

My setut up is a planted Fuval flex 15 gallon tank with 10 Cardinal tetras, 10 Amano shrimp, 12 cherry shrimp and a Betta.. Water parameters are 5Gh, 5kh, Ph@ 7.0, Ammonia @ 0, Nitrites @ 0, Nitrates @ 10-15 ppm, TDS 380 ish....I have a growth in the Aquarium, that I cannot identify nor find...

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...
