Plants are probably the most expensive thing though, my success rate it pretty low. Although my Amazon sword is having babies.

Discussion Things you wish you knew when upgrading to a bigger tank.

I'd love to get thoughts about your first time upgrading tanks. 😊

We currently have a 6G for our betta and shrimps.

The shrimps aren't becoming snacks as Sushi is mostly chill (lucky us) and the tank is heavily planted. The shrimps have also started having shrimplets. šŸ™Œ

We are saving and planning to get him a 10G as it feels like 6G is small for him to swim around.

What should we be looking out for and anything we should consider trying for another low tech tank?

Also just want to say that this sub has been lovely IME. TY for everyone!

Bonus photo of a scrimp having an underwater Mulan moment. lol.

TYIA!~

Question Is my tank fish ready???

Jokes aside, running a pH of about 6.8 and only plants and pest snails in the tank rn, think the plants would benefit from a water change? I'm using a no filter setup and have tons of fast growers that just got set up, just want to see what the consensus is on water changes for plants only tanks

Showcasing my new farm tank, not a traditional Dutch.

I used to not like posing online but feel like this tank is starting to look gorgeous so want to put it out.

The setup is:
ADA 60P
Chihiro WRGB II 60
Daily dose APT 3
Lights from 9:00AM to 6:00PM
CO2 turn on 3 hours before light and off 1 hour before lights out.

This tank is a little bit past 3 weeks which feel in really quickly. Half pallet I got from trimmings half were emsered grow and I replant the top

This is my first plant tank five weeks old and some of the plants are yellow and translucent .Is it because of my sand cap being too deep or do I need some liquid fertilizers?

Discussion Here’s an answer for what to do with extra floaters.

Thumbnail

66 Upvotes

I feel like this question gets asked often, and some suggestions are to give them away, sell them or trade at your LFS.

I do all of those things but with 11 tanks I still generate a ton of excess floaters and sometimes they also look gnarly and aren’t suitable for those purposes.

So I keep European Nightcrawlers in a very simple setup inside my apartment. It’s a small 3 bin 15 gallon tote setup and It does not smell at all. 90% of their diet is used coffee grounds and floating plants.

I get amazing castings that I use for my indoor plants (pic 2) and make teas from (pic 4) and in collecting this small amount (9.5 ounces) I also get a ton of baby earthworms (pic 3) which are perfect food for a few of my fish.

It’s an excellent way to generate 0 waste, get some wonderful soil amendments, make a beneficial bacterial soup for inoculating charcoal to make biochar and feed live.

AMA if you’re interested in setting up your own bin!

So... this is my first tank, it's day 11 since it's been planted and it's still cycling. Can someone help me identify this black/grayish growth on my driftwood? Every day it looks like it's appearing in new areas, is it blackbeard, detritus from a few of my plants having died or normal, beneficial fungal growth or something else?

4ft low boy AquaOne OptiClear 120

Bought this the other day for a setup which will be viewed from both sides (in a wall cavity).

Question is…. What is a decent option for filters other than a canister filter? Im thinking one hang on the back (something like a fluval AC) on one end won’t provide enough flow. I have a Fluval AC50 on another planted tank and it’s been great tbh.

Would 2 HOB Fluval’s (one on each end) be decent enough?

Any recommendations is greatly appreciated.

By the way, the ā€œblackā€ dots on the leaf are actually dark green in person I’m pretty sure it’s just algae and harmless. I’m referring to the black patches at the base and possibly on the rhizome

Tank My 1 month old 15 gallon tank

About 1 months ago I tore down my old 15-gallon Dutch tank. I had started neglecting it a bit and felt like it was the right time to try something new.

This time I wanted to build a scape around hardscape rather than just plants. I always felt that rocks and wood give a tank a lot more character and make it look more unique.

The tank is running on DIY CO2, which I disperse using an internal filter, along with a SunSun HBL-303 HOB filter.

Originally, I had Bacopa on the far left and Monte Carlo as the carpet (mostly trying to save what was left from the previous tank). As the tank matured, I swapped the Bacopa for Ludwigia repens and replaced the Monte Carlo with dwarf hairgrass.

I’m honestly really happy with how it’s growing in. It’s still got a long way to go, but every week it looks a little better.
