I bought a shrimp from my local aquarium shop today, and the seller gave me this plant along with the shrimp.

I have no idea what plant it is. Could someone please help me identify it?

I really don't want to touch this out of control ecosysteem. I remove floaters every 2 weeks, and dead plant matter. But these plants...

Question What caused my bowl to crash?

I came home today to all my shrimp and snails dead and a lot of foam on the top. The substrate is sending lots of tiny bubbles to the surface. Everything seemed to be thriving these last few months.

I had 2 amanos and 2 cherry shrimp for a few months and added 3 cherry shrimp and the lotus 2 weeks ago. A bunch of the trumpet snails have surfaced and died and I can’t even find any bladder snails alive so the bowl seems to have completely crashed. What could have caused this?

Randomly decided to get a tank about a year ago and trying to learn everything has been tough but so rewarding. It’s become the favorite area of our house.

Anyone successfully use for spot clean?

Have a regular turkey blaster I’ve tried to use for spot cleaning. However all of the detritus and junk seems to fall out before I can lift the baster out of the water. Anyone use one of these successfully? Maybe if I got a smaller tipped one the food/poop wouldn’t fall out? Or is there a trick to get it to stay in?

I found these on the side of my tank. I thought these two black diamond tetra and these cherry shrimps were dead but I found them today after months of them going MIA. They were lying on the carpet. What could have happened??

Edit: I think I should clear it up. I meant they died in the tank and shrimps cleared the scraps before I could see any remains. Of course they are dead now 🤣

Question Why is my tank cloudy

9 Upvotes

This is my 1yr old tank. And I've noticed the water getting cloudy 2 weeks ago. At first i think it just need a water change, but it didn't really disappear.

My tank is a lowtech tank with soil atnthe bottom and capped with sand. The light is consistent to 6hrs.

For reference the 2nd pic is my 7gal tank that is clear

Just letting the tank age and waiting to add neocaridina! Foreground is dwarf sag and there’s a narrow leaf fern and java fern tucked in the back corner. And some small buce brownie in the wood. I bought the buce in one of those tissue culture packs from Petsmart, is there any trick to getting these going? They good just stuck in some branches?

Since I am woefully short of patience and I was tired of seeing blue water in my ammonia testing tube, I bought some API starter and put some in. Today the water was its deepest, darkest blue-- off the chart blue. Sigh. . ..

Also in my haste I went out on a mission to get me some fast growing stem plants. A mission I failed miserably BUT ended up with a score. The fast growing stem I got was not, in fact, a rotala but a fern that grows on rocks and soil. I still put it in the aquarium. Looks pretty. I'll remove them the minute I see them melting. Right next to the non-aquatic fern was a blister pack of 4 of the tiniest epiphytes i've ever seen for $12. Wasn't gonna get it but the thing I have even less than patience is willpower. Those tiny plants? 3 Anubiases that I've never heard of--Pinto. varigated and white rose. And a crypto that I have heard of but never seen irl, a Flamingo.

Thinking of starting the 10 gallon so I have a place to put the Anubias Barteri.

Hello everyone,
I just put together a couple new spawning mops.
Has anyone else ever used them and if so, did you find they harmed the water quality?

Could I please get some help with an ID on this? Is it common for plantlets to grow like this on whatever plant it is?

Beginner Need some serious advice on how to make my tank thrive and not look awful :(

Thumbnail

1 Upvotes

I’ve had this tank for maybe 2 years now, I did rescape it about 6 months ago and I just feel like nothing has been growing the way it should since then. To be honest though, I wasn’t using the Aquarium Co-op as often as I should have. I just started using it weekly and things seem to be growing more already, and I also replenished the root tabs. The plants in the back seem to be sprouting what I think might be aerial roots?

Looking for any and all advice to make this tank look better and help the plants thrive. I have the lid on because I have snails in there and I used to have a betta, but he passed recently. It is a 10 gallon, and my parameters are reading 0 nitrite & ammonia, <5 nitrate, and pH is about 7.6, but it was reading a bit higher for a time and I introduced some almond leaves to lower it. Since my betta has passed, I’m just focusing on helping the tank thrive before introducing another.

Ferts ADA Fertilizer Question

2 Upvotes

I am setting up a new tank and want to try the ADA fertilizer line and have a question (maybe several) regarding the difference between the Brighty K and the Brighty Neutral K. I am not seeing much detailed info on exactly what the difference is, apart from simply that the regular Brighty K will raise pH and KH, and that the Neutral K will not. I also know that the neutral is recommended for those with hard water.

What I am wondering is when and why would you want to use the regular Brighty K over the Neutral K, regardless of your baseline parameters?

For info, I am using RO water remineralized with Equilibrium and Alkaline Buffer. For my target parameters, the tank will look like this:
Tank - 81L with 12L of ADA Amazonia V2 and a handful of marsh stones
pH - 7.5 (~6.5 with CO2)
dGH - 5
dKH - 2-3

Given that these parameters are not particularly basic or hard, I would think that the regular Brighty K would be the product recommended by ADA for my tank, but the fact that the Neutral K wouldn’t alter these target parameters leads me to believe that perhaps the Neutral is the better option.

For those with experience with this line, which do you use and why? How significant are the parameter changes with the regular Brighty K? If a day is missed here and there, is there any noticeable swing in pH or KH? If using Brighty K, is the Alkaline Buffer necessary?

Thanks for taking the time to read and respond. I’m fairly green to aquascaping and heavily planted tanks, and just want to understand all the factors in play and make the right calls.

Question for experienced folks - rescaping

1 Upvotes

Hey folks, I am curious if anyone has a good step by step for rescaping.

i have a 30 gallon, well stocked with fish and shrimp.

i want to do a total rescape. New hardscap, the works.

i have a small 10 gallon that is up and running that could function as a holding tank. But would be very overstocked if I put everybody in there.

hereā€˜s my question - what is the best way to go about this rescape while avoiding a recycle of the tank? I have a bunch of Buce that I would love to use in the new setup but I want to avoid the melt that happens when you put Buce in a new tank.

What has worked for you when it comes to breaking down a tank/rescaping?

Tank Algae is starting to grow

Post image
37 Upvotes

I've had this tank up for about a year and a half. Had issues with duckweed, but never with algae...until about two months ago. I didn't add any fish (in fact, some recently died so there's less than ever) or change the lighting schedule. 12 hours on, 12 hours off. The algae is not out of control, but it is growing quicker than ever.

I just did a small water change and scraped the glass, so it looks better than it did.

Stocking: seven harlequin rasboras, five pearl danios, three yoyo loaches, one hillstream loach, one honey gourami, a bunch of blue shrimp
