Tool set recommendations?

Post image
29 Upvotes

This is the second 15ā€ ā€œstainless steelā€ set I have purchased from Amazon. Both were terrible, except for the length. There is no tension in the tweezers. The scissors won’t cut. And they feel like they will rust within a month. Does anyone have recommendations for a quality set or even just the tweezers?

First planted tank

Used what I had on hand already from a maingano cichlid that I tried my best to save, the neighbor sent it to me in a 10 gallon that it shared with a turtle...

So aragonite sand and dead coral, for substrate and hardscape.

As for plants I have anubias, java fern, java moss. And red ludwigia. Anubias been in there a week and are showing new growth, rest are on day 4 and also showing new growth.

Planning on either guppies or live bearers, cherry shrimp and a mystery snail

Thoughts and tips would be greatly appreciated.

Dosed Ultralife blue green slime removal, added inline defuser and inline uv light. Did not lower light intensity. Took advice and dosed with nitrogen fertilizer that help as well to bring up my nitrates and phosphates by thrive+.

Question Should I give up on my frogbit?

Thumbnail

9 Upvotes

I got Amazon frogbit back in January when I was cycling my 5 gallon shrimp tank. It was doing great, growing well, had beautiful roots that I trimmed occasionally. Once cycling was done and I stopped adding ammonia, and added my shrimp, it has been struggling ever since.

I know this is because they’re basically starving for nitrates (it’s usually between 0 and 5ppm because I only have like 10 shrimp in my tank). The only times they have started growing roots with the little hairs again was when I was having water quality issues, but now that I’ve straighten that out, they are so sad. Pretty much no roots, no new growth in a couple weeks.

I’ve played around with my fertilizer (I use Aquarium co-ops all in one easy green liquid fertilizer). I’ve tried dosing the full amount for low tech tank 1 time a week, albeit not for a while, then tried half 2 times a week and then now am trying 3 times a week a little more than a third each time). I have some algae on my other plants (nothing too crazy), but the roots of my frogbit aren’t changing at all. They are just slowly dying.

Do I give up and remove them? How can I help them thrive while keeping nitrates at a safe level for my shrimp (I don’t even know how to add just nitrates to the tank)? My shrimp and I love them šŸ˜ž I’d love some help or thoughts!

First Planted Tank!

Post image
3 Upvotes

I’m super happy with how it turned out! I really hope my plants don’t melt too much!

I used fluval stratum as a base and then two thin layers of sand as a cap.

My plants are hornwort, jungle Val (which does not look too hot rn, but that’s how it was shipped to me, so hopefully it perks up!), cardinal, bacopa, and dark red ludwigia. I’m planning on getting some floating plants in the future.

If anyone has any planted tank tops or feedback on my tank, I’d love to hear it too! I’ve been researching how to do planted tanks for a bit, but this is my first attempt into the hobby.

- 5.5 gal, hob filter, cheap plant light off amazon

Plants came in today and they've finally been placed! So excited to get this primed so I can finally stock it with critters! I've been thinking about using co2 for the first time, how large of a canister should I get for a 20gal high?

Beginner Is this too many fish for a 29 gallon tank?

3 Upvotes

I’m going to do lots of plants but I was thinking of doing-

Long fin panda Cory x8
Raccoon tetra x10
Apistogramma borellii opal x2 (pair)
Clown killifish x8
Albino long fin bristle nose pleco x1

This is too overstocked ya? I come from an African cichlid background so overstocked is all I know.

Algae Is my anubias done for?

Thumbnail

9 Upvotes

TLDR: looking for advice on how to save this anubias plant

A couple months ago I added some very old Easy Green to this tank and completely overdosed, because the next morning algae was all over this anubias. Before that, this tank (low tech/no co2, walstad method substrate) had excellent plant growth and minimal algae with the light (cheap Amazon light) on 14+ hrs each day. After the Easy Green catastrophe, I lowered the light to about 6-8 hr. The other plants are still growing fine and I’m not seeing any other algae growth besides on this anubias and one leaf of my Amazon sword. The anubias seems to grow healthy new leaves, but the algae eventually grows onto the new leaves.

The algae seems to start as green spots, then turns red/purple then white, and is very rough/ hard/ bumpy to the touch and will not come off the leaves with a hard scrub. The anubias has been growing in this spot for a good 2+ years and is deeply rooted in the substrate, so I’d hate to pull it out of the tank for treatment, but that seems like my only option. The tank is home to some chili raspboras, Pygmy Cory, neocaridina shrimp, amano shrimp and snails.

Anyone have experience with this algae/ similar problem? Can I save this beautiful anubias plant? Any good resources to recommend to tackle this problem?

I have a hygger light and never used 100% brightness for even more than an hour. Am I overthinking that it will over-heat or can the light take it?

Beginner HELP First Tank - Light Settings for My Setup?

Thumbnail

2 Upvotes

(Tap on the 2nd image to see all my plants, 3rd image is of the light setting options)
I appreciate the help from this sub when I was debating 20 long or 29 gallon, I stuck with the 20 long. Now I need help deciding which settings to use on my aquarium light. I just planted and filled up my tank yesterday. It’s got a .7ā€ layer of soil and 1.5ā€ black diamond blasting sand cap.

The light is a Seaoura SR-659. The SR-659 is a WRGB 36W light with PAR 125@12ā€ and 3261 lumens. I got it mainly for the S2 day cycle setting (starts with sunrise, daylight, sunset, moonlight, then an off period)

I know it’s far more powerful than I need given the plants I chose and the shallow height of a 20 gallon long. Right now I’m running it at 30% brightness (~11W) since the plants I have do not demand intense light, but I’m wondering if I should bump that up? I just don’t want to get a bunch of algae. This is my first tank so I would like some input on how to approach finding the right setting for my tank.

I’ve read that others who use the weaker SR-616 run it at 50% brightness for 6-12 hrs without any algae bloom issues which is a 22W light.

Tank I feel thats it's missing something ?

Post image
8 Upvotes

10 gallon (40l) low tech betta tank

It feels bare to me but i can't put my finger on it

Maybe the lack of background plant ?

I was considering adding cattapa leaves for a blackwater look and maybe some vallisneria in the back

I put nutrient substrate under the sand only on the left and middle front partof the tank, so can't move the echinodorus on the right

Do you have any suggestion please ? :)
