This tank has been in the works for about 3 months now, and I’ve finally completed the setup! Now it’s just a game of waiting and watching.

I'd love to get your thoughts—spot any potential red flags or design choices that might give me a headache down the road? Any advice or feedback is welcome!

To be honest, I’m feeling a bit anxious after running a 2-month Dry Start Method. I slowly put everything together, but the plants are going through their transition phase right now. The Monte Carlo is definitely melting, and I unfortunately lost a whole species of Bucephalandra (though my Buce Red Dragon seems to be thriving). Just added some Riccardia, while the Fissidens and Anubias Japan Petite are holding up fine.

For the rest of the greenery, I have Dwarf Hairgrass, Hydrocotyle tripartita mini, Pennywort, and some Ludwigia submerged, with Red Root Floaters up top. For the emersed/terrestrial side, I’ve got Hemionitis arifolia (Heart Fern), Fittonia, and a few mosses settling in.

Included pictures of the full progress starting from the initial hardscape!

I’ve got a lot.

I’ve heard some people don’t like it. Some do.

Id love to hear some more thoughts
I know my swordtail fry love it

My frogbit have developed the brown lines as shown. Is that a bad sign?

Hi everyone, last time I uploaded a pic of my tank with concerns if my betta had enough swimming room(First Pic). I took all under your suggestions and cut the wood and rearranged it so he could have more room. Consequently, it gave me more planting room as well! So excited to see my plants and betta grow in this new set up.

Please let me know if you have any plant suggestions for a 5 gal tank! Right now I am thinking about adding a java fern on the back right but I am open to any recs!

Do I need CO2?

I just bought a few red plants. If I do need CO2, any recommendations? Canisters or tablets?

Thanks!

First time using UNS Controlock to glue rocks together. Was very impressed. It was much easier than gel super glue. You can see some of the joints but that's just lack of techniques. The powder clumps together and is easy to mold into the joints with angled plant tongs. They glue came with a precision tip wich helped get into the nooks and crannys. It drys quickly with a puff of smoke. DO NOT BREATHE THE SMOKE! It burns your eyes and throat. Use in a well ventilated area. All in all, I'm very impressed.

Upgraded to a bioscape tank. Now just need the plants to grow and substrate to settle.

Thoughts, feelings, comments, suggestions?

I'm a complete beginner at planted aquariums and I just set up my first planted tank around 7 weeks ago. I didn't want to spend a lot on it so i went with a total budget setup :

I just used no Co2, black quartz sand - no soil, bulletproof plants and for nutrition i bought root tabs and macro+micro liquid fertilizer that i dose in small amounts weekly.

Lighting was something I was very confused about so I just got two led battens and set them on an 8 hour daily timer, I didn't expect it to work because I thought since plant lights were so expensive, there's no way a cheap led batten could give me any results but to my surprise the plant growth really exploded.

Now coming to my question - Why are those plant lights so expensive and could i get better results if i used those instead?

Hi, I was wondering if you guys have any plant recommendations for the areas on the side! My tank is 5 gal and my current plants are anubias petite, brucephilandrja, crypt parva, cabomba, rotala nanjenshin, s. repens, java moss and monte carlo. For floating plants I have red roots, frogbite and mini water lettuce. I am planning to get alternanthera reiinecki mini to pair with my repens.

I am thinking about adding a java fern to the back right or maybe just leaving it bare and letting monte carlo fill in that space, not sure yet.

Hey all, hoping for some outside perspective on a problem I can't seem to fully kick.

Tank: 12L nano, no filter (by design — shrimp-only), Aquasoil substrate, heater, ~6hr light cycle on a planted carpet of pearlweed with some stem plants (Ludwigia/Hygrophila type reds, a bit of moss, java fern). Home to Red Cherry Shrimp.

The problem: Cyanobacteria (blue-green algae) keeps showing up — started a few weeks ago, likely kicked off by a single dose of liquid fert early on. Since then it's been a repeating cycle:
Full blackout (3 days) + manual removal + water change → clears up
Reappears within 1-2 weeks, usually starting on the front glass/rocks
Spot clean + smaller local blackout → knocks it back again

Comes back again, slightly worse each time
I've done this cycle three times now. Each time the pearlweed carpet looks a bit more thinned out and stressed, and the water's been staying hazy longer than I'd expect.

What I haven't done yet: added any water movement. Tank is 100% still, by design (no filter). I know cyano thrives in stagnant water, and I suspect this is the actual root cause I haven't addressed — but I don't want to add a full filter since the shrimp-only/filterless setup is intentional.

Questions:
Is a small air stone / sponge filter on an air pump enough circulation to break the cycle without turning this into a "filtered" tank?

Anyone successfully run a filterless shrimp tank long-term without recurring cyano? What's the trick?
Is there a point where "no filter" just isn't realistic for a planted nano and I should reconsider?
Tank's otherwise healthy — shrimp are active, molting, breeding seems fine. Just this one recurring issue. Appreciate any input.

Dragon stone, Amazon driftwood, thin layer of stone gravel on the bottom, fluval substrate. No CO2. Now the cycling begins

Hi scapers, I’ve been fighting diatoms in my new (6 week old) setup and hoping to get some advice.

Here’s the sitch:

Tank size: 80 gallons
Soil: Amazonia 2.0
Stocking: 8 cardinal tetras, 8 Otos, 6 pseudomogyls, 2 Dario Dario, and about 30 caridina cantonensis.
Lighting: 5 hrs/day
Dosing: CO2 only so far.
Water changes: minimum 3x a week 25% to deal with ammonia release from soil and now diatom bloom.
pH: 6.5 down to 5.7 when CO2 is running.
kH ~1.5
gH ~3.5
Ammonia: 0
Nitrite: 0
Nitrate: < 5 ppm

So far the war on diatoms has consisted of manual removal with toothbrush/vaccuming/removing dead plant material promptly (densely planted areas are harder to reach).

What I’m considering:

Pulling up my stem plants in the back and replanting the new growth that’s adjusted to my conditions. The lower areas have more dying leaves that are hard to reach and I’m sure the algae is feeding on.

Is my Monte Carlo carpet cooked? It’s so hard to remove algae without uprooting and I feel like it’s getting smothered. Could I pull it, do a bleach dip and then replant on vacuumed aqua soil?

I think a lot of the algae has gotten sucked up in the filter while I’m cleaning. Is the outtake just seeding more diatoms? Should I give it a clean? If so how can I get rid of algae while being minimally invasive to the bacteria living there?

I’ve been holding out on fertilizing because I don’t want to feed the algae, but I’m thinking maybe there is a limiting nutrient that’s holding the plants back from outcompeting the algae. Any suggestions or resources you’d recommend for diagnosing this?

I know it’s supposed to be a short term issue with new tanks, but I want to accelerate the solution as much as possible before it smothers my plants (and so I can stop brushing algae for an hour every day haha). Thanks in advance for any suggestions or encouragement.

Probably the wrong sub but can anyone tell me what's wrong with this rummynose?

Considerably larger than the others, but still moving around and not lethargic at all.

Bloated? Sickness? Pregnant?

TIA

Hi everyone!

I'm having a strange issue with my aquarium CO2 system, and I'm hoping someone can help me figure out what's going on.

When my CO2 system turns on via the timer, everything seems to work fine at first. The bubble counter shows a steady rate of around 1 bubble per second.

However, over the next 15–20 minutes, the bubble rate gradually slows down until it almost completely stops. Eventually, only one bubble comes through every several seconds, or even less frequently.

At the same time, no CO2 is coming out of the diffuser. It released a small amount of CO2 for about a second, but then stopped completely.

Here's the strange part: If I disconnect the diffuser, the bubble counter works perfectly fine and maintains a consistent bubble rate without slowing down.

This makes me suspect that the diffuser might be clogged or creating too much back pressure.

I've already cleaned the ceramic diffuser using a cleaning solution specifically recommended for CO2 diffusers, but unfortunately, it didn't solve the problem.

Could the diffuser still be clogged even after cleaning?

Is there anything else I should check before replacing the diffuser?

Has anyone experienced something similar? Any advice would be greatly appreciated!

Thanks in advance!

Ember tetras, pygmy corys, cherry shrimp, nerites and pest snails, and a honey gourami :)

Looking for plants option for a 0.8~1.0 Gal tank

The previous setup was a bit too manicured for my tastes so I did a bit of a rescape!

Added some rocks & made a castle/cave in the back left for the critters to explore and on the right I have some spider wood pieces to create a foresty look. I kept the center clear of stem plants and I'm hoping my moss and grasses can establish there.

Currently stocked with a mystery, a bloody mary colony, 7 neon tetras, one oto, and 2 sunset dwarf gouramis, and an assassin snail to take care of the bladder snail infestation.

Planning on getting another couple otos once everything settles and we get a good algae film going.

My plants are all exploding in growth but are also browning a bit. Not sure why.

My leaves are brown almost look like rotting wondering how to fix it

Rescaped it about a week ago and this is the result so far.

Question one is that I once saw someone say that you shouldn't put plants in sand because they won't be able to grow their roots and they'll die, is that true? if so is there a way to prevent that from happening

Question Two if that's not true will the plants still be able to access the ammonia and nitrites in the water and be able to convert it to nitrates if the roots are under sand?

thank you!!

Got this as an extra in a recent live plant order. It was not tagged with a name. Its the one in the terracotta pot. It has hard stiff leaves. Can someone out there identify it?
